In the paragraph number 〇〇4 of the Japanese Patent Laid-Open No. Hei 8-148360, it is described that the power transmission frequency can be selected. Other examples of the configuration described above are described in Japanese Laid-Open Patent Publication No. Hei 4-122007. This Japanese Patent Laid-Open No. 4122〇〇7 is incorporated. The self-loaded planar spiral coil forms a 25 ® winding with a straight lacquered copper wire enamel C〇PPer Wire to form an outer diameter of 80 mm, 319286 6 ^31432, an internal control of 24 mm, and no core portion. The coil was used as Comparative Example 1. When these coils are opposed to each other and connected to the power source, the primary side (input side) is used, and the output by the electromagnetic induction is used as the secondary side (output side). In Japanese Laid-Open Patent Publication No. Hei 6-2911-7, a coil formed by winding a conductor is described, and the eddy current loss and the skin effect (skineffeet) are described, and the frequency is increased. The technical content of the parent flow resistance of the V-body of the j-ring is increased. In terms of its avoidance method, it is described that a plurality of single wires are formed into a flat cable (flat == a wire forming a coil, and a frequency characteristic of an alternating current resistor compared with a coil using a % of other wires) is described. In the application of this application, 'the terms used will be different depending on the documents cited. Therefore, the first one contains the main 筮 面 surface, which is used to explain it.

If the electric power is not used, the system has Various applications of electric power At the time of the operation, the mutual inductance is used to transmit the electric power and the advantage. However, the configuration of the power transmission coil in the conventional technique and the characteristic and the effect is confirmed. Therefore, it is attempted to investigate the power transmission 7 319286 1331432. And the power receiving coil is a conventional example of a detachable power transmission device and a coil of a transmission device. First, the Japanese Patent Laid-Open Publication No. Hei 8-14836 公报 discloses that the power transmission frequency can be selected. It is a variable device (variable =). One time, (four) and second time line _ are not separable, but it can be seen that a transformer designed for commercial power supply of z to 60 Hz cannot be used at any frequency, for example, 5 Hz or 1 G kHz. The lower limit and the upper limit of the usable frequency are present as the electric system. However, the conventional technique in which the frequency range is used in the case of the electrosurgical ring is further described as 'inseparable in the primary coil and the secondary coil.

In the case of the air-core coils described in the Japanese Patent Laid-Open No. Hei 8-148360, and the Japanese Patent Publication No. 4-122007, the air core coils are all two parent cases. The flat spiral coil is not equipped with magnetic material, that is, the content of the performance improvement cannot be achieved. The right is not equipped with the machine ==^ lies in its shape, especially equipped with the title...: 溥 ' 即 即 即 安装 安装 安装 -6 内In the small-capacity portable machine of the secondary battery, it is required to reduce the coil volume as much as possible based on the 319286 8 ^ system. In order to increase the electric power, it is not necessary to arrange a plate made of a magnetic material on the opposite side of the opposite direction of the coil 2 as described in Japanese Patent Laid-Open Publication No. Hei 8-i4836g. However, at this time, there is a problem that the coil volume is increased and it is difficult to machine.泛, -円ί Γ 日本 日本 请 δ δ 请 请 _ 请 请 请 请 请 请 请 请 请 请 请 请 请 请 请 请 请 请 = = = = = = = = = = = = = = = = - = When the magnetic material shown above is not provided in the coil of the power transmission coil or the power receiving coil, the power transmission performance cannot be improved. This is based on the fact that the maximum value of the magnetic γ thickness is set to 5 nm, which is also described in Japanese Patent Laid-Open No. Hei 8-148, the entire disclosure of which is incorporated herein by reference. However, when the overall thickness of the coil is 5 mm or more, there is a problem that it cannot be equipped in a mobile phone. The method of comparing the comparative example with the embodiment is described in the Japanese Patent Application Laid-Open No. Hei 8-148360, and the Japanese Patent Publication No. Hei 4-122007, and the spiral coil of the plane is not effectively transmitted. Technical content of electricity. However, the reasons for this are not stated. In the Japanese Patent Publication No. Hei 8-148360, the disclosure of the air-core coils as exemplified in Comparative Example 1 is attempted. In the first application, the inventors of the present application made the same coil as that disclosed in Japanese Laid-Open Patent Publication No. Hei No. 8 14836 No., and measured the characteristics of the aforementioned coil. In the coil system described in the comparative example, only a bundle of 100 insulated copper wires having a diameter of 1 m and a diameter of 1.5 mm is formed as a thick wire having a wire diameter of 1.5 mm. . Therefore, the self-inductance (_ 319286 9 1331432 inductance) is small, about 〇_8 # Η, and the mutual inductance is also small due to the shape of the coil. Therefore, the power factor is lowered, and the apparent power and the reactive power become large. In addition, since the wire diameter is small and the number of turns is small, there is an effective series resistance of the coil in the frequency l〇0 kHz described in paragraph number 〇〇51 of Japanese Patent Laid-Open No. Hei 8-148360. A problem of too small of about 17m Ω. In the 38th aspect of the present invention, an equivalent circuit diagram of the coil of the comparative example 1 described in the Japanese Patent Application Laid-Open No. Hei No. Hei. As shown in the % diagram of the present application, two coils are used, and the coils are configured by the power transmission coils! And a transformer composed of the power receiving coil 2. When the frequency is 100 kHz, the impedance Z of the secondary side coil observed by the parent current source (10) when the load resistance rl is set to 忉 Ω is formed to have a very small value, which is Z = about 〇 · 6 Ω. In the % diagram of the present application, (the internal resistance of the AC power supply ν indicated by R3 is generally Μ) = Therefore, when the aforementioned under-current coil is connected to the AC power supply ,, the AC power supply V is nearly short-circuited. The resistors consume a considerable amount of power, and the internal source of the =^ source V cannot transmit power efficiently, and the power value that can be transmitted is also reduced. 、, σ Originally, the patent is opened on the special 8_14836 The coil is described in the opposite direction of the coil. The opposite direction (four) is opposite (four) and the coil is opposite to the 睥刼Mθ H card, and mi is used to increase the coupling coefficient. Therefore, In the case of an air-core coil, it is not the most optimized one. The 319286 10 1331432 material disclosed in the Japanese Patent Laid-Open No. 4/12 Supplementary Bulletin is discussed. In Japanese Patent Laid-Open No. 4_122〇〇7 j is compared with the example 1 in the case of the Japanese Patent Application No. 4,12 Coffee 7 = Report No. 7 for the rough calculation, when the relative distance of the coil is t, the frequency f = the surface z, the secondary side load current 12 = about 〇·5α 日日, can be transported efficiently; 7 = about 65% to transmit 2 The power of the side power, however, is incomprehensible in the measured results. In the patent special opening (10), the bulletin ^, in the same coil as j _, 2 as a variable, because the winding ratio is ι: ι : 2: The side voltage should only be below the } sub-side. However, when the meter is entered according to the above, the voltage value of the secondary side is V $ V2=2〇w = two. V' is in the 曰Japanese Patent Laid-Open No. 4/122. No. 7 of the Japanese Patent Publication No. 07: the voltage applied to the under-side coil is 29 V when V1 = 29 V. That is, the variable forming the winding ratio i: ! without the boosting action Crying is = "pressure V (four) V, _ ^ 2 = the effect of the boosting effect of the surgery; only in the comparative example 'in the first embodiment, if the second current of the current graph is about 〇.5A, the same is formed. The actual measurement (4) shows the day = the fourth side of the flat 4 side of the public can be seen in the above-mentioned Japanese Patent Special Publication No. 4_122GG7, "the theory", in addition to the Japanese Patent Special Open 4-122007? : If the coil of the comparative example i is empty, the reason for the poor regenerative energy can be added. The brother of the second paragraph is the paragraph number circle of the Japanese Patent Publication No. 6_29117. As shown in the e, the eddy current loss and the skin effect increase the equivalent series resistance of the coil when the frequency rises. It is known that the characteristic of the single conductor is 319286 11 thick and the effect is more obvious.

When the knots of the scorpion worm (10) and the tiantian feng 5 〇 kiiZ, the coil # effect string is 〇266 Ω, and the Ω is about 3 times or more. The DC resistance of the coil is about 0.08. The power failure control diagram in Figure 36 of this application is based on the AC power supply ν, which means that it is the I electric power; 'v this application, the third 8 R1 A - ^ ma The internal resistance of V. Is the equivalent series f resistance of = Han circle i. 4th series resistor for R24 power. RL is the resistance. The load circuit that is connected to the electric control circuit 4 is used in both the i-side and the secondary-side coils as a comparative example of the Japanese Patent Publication No. 4-122007, as shown in Fig. 38, etc. When the series is connected in series, the resistor R1 is connected in series to the AC resistor R2 and connected in series to the load resistor RL, because the power loss occurs in at least two parts of R1 and R2. In order to avoid the occurrence of 'reducing the frequency to reduce the aforementioned skin effect, eddy current loss'. But 7^, when the frequency is lowered, the reactance of the coil. As a result, the impedance 2 of the power transmission coil is lowered, and the apparent power is excessively applied to the power transmission line. Then, an excessive current due to the apparent electric power flows to the power transmission coil 1, and power loss due to the equivalent series resistance R1 and the internal resistance R3 of the parent current power source occurs. Therefore, in the embodiment of Japanese Laid-Open Patent Publication No. Hei-4-122007, the inductance and reactance of the coil are ensured, and the magnetic material is provided in order to reduce the apparent power. When using a coil with an air core, in order to ensure reactance, it is necessary to implement a coil that can be operated at a frequency of 319286 12 1331432. That is, a coil having a low series resistance R1 is sufficient.冋's rate and equivalent.

That is, when the improvement rate of the frequency characteristic of the equivalent series resistance is not higher than the rate of decrease of the inductance, it cannot be said that the coil having good performance has been realized. In other words, if the Q of the coil is not raised at a higher frequency, it cannot be said that the coil having good performance has been realized.

In addition, as for the example of the example of the Japanese Patent Publication No. Hei 6-29117, the following example is applied: ... = = load = 1 number of outer dimensions of the coil.

In addition, in the bA report, the Noro number 0020, 0021, and Tuling' have disclosed that the flat cable is wound into a flat spiral ring, but the coil of the third figure is formed into a spiral of the other plate by using other wires. The performance or function of the coil is compared; In addition, the coils relating to Fig. 3 can be used without any description. The content of Philippe Transport is also completed. In order to achieve a good performance of the power transmission coil, in order to protect the self-inductance, mutual inductance (face factor) and avoid the coil caused by the electric power To generate heat, it is necessary to select a properly constructed line 3 ° ^ 'The characteristic of the coil must be made to determine the operating characteristic of the coil. It is not sufficient to improve the frequency characteristics of the equivalent series resistance of the coil. As shown in the figure, the power transmission performance of the coil for winding a wire which is wound into a flat plate and has a single-layer spiral shape is a conventional technique: by providing a magnetic material or the like for power transmission performance, A conventional technique in which the relationship between the equivalent series resistance of the power transmission coil and the frequency, and the configuration of the power transmission coil, which are one of the factors of the right and left power transmission performance, does not exist. Also in the prior art, a power transmission coil suitable for use in a coil of a power transmission device and spiraled in an early layer is not realized. In addition, the winding 319286 14 弋= is not specified, and the power transmission of the power transmission line of the spin-shaped power transmission is not possible. [Inventive content] It is possible to provide power in a prescribed conventional technique. Transmitting _:: use; force =: sex = power transmission performance and operation method of the power transmission device. The power supply unit and the power receiving unit are separable power = and =, and the power transmission unit that converts the direct current power into the alternating current power η phase electric coil is included. And at least including the load power receiving unit, and the power transmission coil and the power receiving unit transmit power to the power receiving unit. Set the relative series resistance of the square coil I body to $ = resistance. The ratio of the equivalent series electric current of the one-to-one coil is n (Hz), and the electric power is turned to the "highest frequency of the intestine", and the η is the upper Hz or more. Line () square coil 'wire fa is set at a frequency that does not reach η. In the present invention, the power transmission performance can be improved more than the conventional technique by using a coil having a π of 100 kHz or more and a frequency of the power conversion means fa at a frequency less than Π. Preferably, the equivalent series resistance of the coil to the square coil when the coil is opened to the other side is set to Rn ( Ω ). When the highest frequency of RS > Rn_ is satisfied as f2 (Hz), the output frequency & 319286 15 is set at a frequency less than f2. , Rw = medium: by the frequency of the transmission of power, full ... & prescribed " μ plus select the equivalent series fia Rw smaller coil, and can be used to draw a frequency range suitable for power transmission. > Intestinal 1 = the coil that satisfies the Rs heart variable in the frequency used to transmit power, so that the coil unit and the two or two of the coils are close to the ideal theoretical characteristics, and It can make the power specialization more than the conventional technology. Preferably, the thermal resistance of one of the coils is set to be the ambient temperature of the place where the allowable operating temperature of one of the coils is set to be (c), and the one coil 5^^ is set to be a (C). When the power is transmitted, the current is set to Ia (A), and in the output frequency fa, the square coil satisfies the relationship of R to (Tw - Ta) / , and the power transmission unit Power is transmitted to the power receiving unit. As described above, by specifying the thermal condition of the equivalent series resistance Rw and the alternating current a', it is possible to specify at least the AC current_limit of the square coil, the upper limit of the equivalent series resistance of the square coil, and A frequency region where the series resistance Rw is small. In a preferred embodiment, the wire forming at least one of the coils facing the coil is a single wire to which the insulating coating is applied, and at least one of the coils is formed by winding a single wire into a spiral shape of a single carcass layer. When the maximum diameter of the body of the single conductor is U and the outer diameter of at least one of the coils is D, at least one of the outer diameters D of the coil is the largest diameter. At least more than this, and the number of windings of the wire is a predetermined number of E or more 'at least—the self-inductance of the square coil 319286 16 1331432 • is at least 2 # Η or more. By applying an insulating covering member to the wire as shown above, it is possible to prevent the wire from being oxidized and to prevent short-circuiting between adjacent wires. Further, by specifying the diameter D and the number of turns of the coil, the required self-inductance can be ensured, and the desired coupling coefficient can be secured in a predetermined relative distance between the two coils. In another preferred embodiment t, at least one of the opposing coils includes a plurality of wires, and each of the wires is formed by applying an insulating covering to an aggregate of a plurality of bare single wires having a maximum diameter of 〇3 inm. The at least-square coil system is formed by applying an insulation fracture to a plurality of bare single-conductor aggregates, and the wires are closely wound into a single layer or a plurality of spirals, and the maximum diameter of the aggregate of the plurality of bare single conductors is set. When d2 is used, when at least one of the outer diameters of the coils is D, at least one of the outer diameters D of the coils is at least 25 times larger than the maximum diameter, and the number of windings of the wires is a predetermined number of turns or more, and at least one of the coils has a self-inductance of At least 2/zH or more. In the present invention, the same effects as those of the above-described invention are achieved, and the eddy current loss due to the magnetic flux penetrating the conductor increases in proportion to the volume of the conductor, so that an aggregate of bare single conductors of less than 3 mm is formed as at least The wire of one of the coils increases the surface area of the conductor, thereby suppressing an increase in the equivalent series resistance due to eddy current loss and skin effect. In a further preferred embodiment, an insulator layer is disposed inside the wire in the wire forming at least one of the coils facing the coil, and the cross-sectional area of the insulator layer is 11% or more of the total cross-sectional area of the wire, and at least the square coil system is provided. The wire with the insulator layer is tightly wound into a single layer or a plurality of layers of spirals. When the maximum diameter of the 319286 17 words and the conductor of the color limb layer is set to be, the external control of at least one coil is set to D. At least one of the coil outer diameters D is at least the maximum diameter, and the number of windings of the wire is a predetermined resistance or more, and at least one of the coils has a self-inductance of at least 2 #H or more. In this example, the same effect as the above-described invention is achieved, and the (four) flow loss is increased in proportion to the volume of the conductor due to the magnetic flux penetrating the conductor. Therefore, an insulator is provided inside the wire constituting the coil, and the reduction exists in the through-hole. The conductor volume of the magnetic flux path in the wire increases the surface area of the conductor, thereby suppressing an increase in an equivalent string such as the resistance Rw due to eddy current loss and skin effect. The insulating material is provided with an insulating layer inside the wire, and the wire is made flexible, and the bending work of the wire can be easily performed. In the coil of the above configuration, since the equivalent series resistance Rw is low in the wide frequency range and satisfies the frequency range of Rs > Rn g Rw, the power transmission characteristics are excellent. In a further preferred embodiment, the wire is formed by an assembly of a plurality of individual wires respectively applied with an insulating covering, and when the maximum diameter of the conductor in the single wire is set to d4, d4 is selected as 〇 Below 3 faces, the thickness t of the insulating coating is (d4) / 3 〇 or more. In this example, the same effects as the above-described invention are achieved, and the eddy current loss due to the magnetic flux penetrating the conductor is proportional to the volume of the conductor. Therefore, an aggregate of bare single conductors of less than 3 mm is formed as at least The wire of one coil increases the surface area of the conductor, thereby suppressing the increase of the equivalent series resistance Rw due to the eddy current loss and the skin effect. 319286 18 1331432 - plus 0. The coils of the structure are respectively applied a plurality of insulating covering members; a single conductor assembly, and a gap between the conductors and the other conductors adjacent to each of the single conductors is formed by the insulation covering member, and the current flowing to each single conductor occurs. The magnetic flux density is V complex, and the volume of each single wire is small, so the thirst loss can be reduced. Of course, it is also possible to reduce the impact of the skin effect, and it goes without saying. The coils of the above description have a low power frequency characteristic because the equivalent series resistance Rw is low in a wide frequency range and a frequency range satisfying Rs > Rn^Rw is also wide. In other words, at least one of the coils of the guide wire is formed by winding a wire into a flat spiral shape. When the maximum diameter d of the wire is 0.4 or more, 02 mm is provided between the conductors of adjacent wires. In the above gap, when the maximum control d of the wire is less than 44 mm, a gap of d/ 2 (mm) or more is provided between the conductors of the adjacent wires. # When no gap is set on the right side, the magnetic flux generated by each wire runs through the adjacent wires. The undulating loss caused by the magnetic flux penetrating the adjacent wires increases the equivalent series resistance Rw when the frequency rises, but Since the gap is provided, the eddy current loss caused by the magnetic flux penetrating through the adjacent wires can be reduced, so that when the frequency is increased, the increase in the equivalent series resistance Rw of the coil unit can be suppressed. Further, in the coil of the same outer diameter, since the total length of the winding is shortened, the equivalent series resistance can be suppressed to be low. However, the eddy current loss due to the magnetic flux penetrating the conductor increases in proportion to the volume of the conductor, so 319286 19 1331432 5==:==::=::

When the gap width between the conductors of the adjacent conductors in the innermost peripheral portion of the one of the four inner coils is t2, i2 > tl > G, the gap width increases with the == circumference toward the inner circumference. The gap width U provided between the adjacent wires of the innermost peripheral portion is at least 〇2 mm or more. The magnetic flux density generated by the coil is low in the vicinity of the outer peripheral portion, and is on the inner circumference. Therefore, by closely surrounding the outer peripheral portion and unwinding the inner peripheral portion, the magnetic flux density can be set as much as possible on the coil surface. - can prevent and reduce the transmittable power when the relative position to the coil changes. Since the magnetic flux density in the inner peripheral portion is high, eddy current loss can be prevented by providing a gap.

Further, in at least one of the coils, the outer peripheral portion of the lead wire has an insulating layer, and at least one of the outermost peripheral portions of the outermost peripheral portion of the coil is in contact with each other through the insulating layer. Compared with the one set in the inner peripheral portion, since the line length of i匝 provided in the outer peripheral portion is long, the effect of increasing the inductance of the coil is large. Therefore, the inductance of the coil can be ensured. In addition, the 周 在内 在内 在内 在内 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 319 The reason for the increase is to increase the loss, so the ° is 1 gap. The effect of the voids is as described above. In the coil of the above configuration, since the equivalent series resistance Κλυ is low in the wide frequency range, β D is generated. ρ brother two thousand special, ., foot RS> Rn$ Rw also has a wide frequency range, so the power transmission characteristics are good. In a better implementation, the ^ D squares the coil to deform and the coil is formed! It is fixed on at least one of the edge plate or the insulating member. The coil is disposed on the side of the insulating material to protect the coil = edge layer constituting the coil. If an insulating material is placed between the opposing coils, the insulation resistance of the two, '·, ... can be improved. In the case where the two coils are fixed and used as a transformer, the insulation is also improved by providing an insulating material. In the preferred embodiment, the at least one square coil is used as the power transmission line Z or the power receiving coil. One of them is used, and the power transmission coil and the power receiving, the ', and the ring are formed as inseparable, and can be used as a transformer. Among them, unlike the general transformer, the characteristics of the power transmitting f-ring unit and the power receiving coil unit are measured before fixing, and (4) the characteristics of the two coils being electrically opposed. In the case where the transformer originally designed as a whole structure is not in use, the performance cannot be confirmed. However, in the present invention, the characteristics can be measured, and the coil is fixed after actually confirming the power transmission performance. Then, = the transformer with good characteristics of the ratio of the winding of the power receiving coil and the receiving coil to the winding ratio of the receiving coil and the receiving coil can be set at any ratio. According to still another aspect of the present invention, the power transmission device of the power transmission unit 21, 319286 1^^1432, and the power transmission unit, the power transmission unit, the frequency f machine, and the output frequency are included. In the present invention, when the other coil of the one coil unit or the other is short-circuited, the til = equivalent series resistance is set to Rs. The use satisfies Rs > Rw is a coil of 100 kHz or more, and the power is transmitted by the power transmitting unit as shown above, and the electric coil can be used. The electric motor of the electric power can be improved by the electric power. Another other aspect is a power-receiving device including the fork electric power device of the power transmission device described above, and the power receiving unit outputs a frequency fa to go to the α-square coil, and the driver 1 is smashed again. The power transmission unit that does not reach the frequency of fl receives power. In the present invention, the equivalent series resistance w of one of the coil units is the equivalent of the line when the short-circuited another-and-circle is opposite to the square coil. The series resistance is set to ~. By using the frequency that satisfies Rs > Rw The upper coil drives the power receiving c-ring to receive power at a frequency less than η. By the power-receiving unit as described above, the power-receiving power can be used to make the power transmission performance of the power receiving unit (4). The aspect is a power transmission reverse operation method in which the coil of the power transmitting unit and the power receiving unit are dreamed... and the power is transmitted from the power generating unit to the power receiving unit. When the opposite coil is in the square coil unit 4: t is set to Rw (8) The opposite series resistance of the square coil is set to RS (D), and the frequency of the foot Rs > Rw When the frequency of the driving rear ring is set to fd (HZ), the other coil of 2 319 286 22 above (4) is used. The power transmission device sets fd at a frequency less than fl and operates the power transmission operation. When the coils are opposed to each other, the equivalent series resistance RS of the other s1 square coil opposite to the at least one of the wishing μ coils when the coil is short-circuited with the at least one square coil is greater than the equivalent f-connected resistance Rw of the sigma-square coil precursors, Therefore, it is possible to select a coil with a smaller equivalent series resistance Rw, and == is suitable for power transmission. The frequency range of the transmission. Next, as described above, it can be confirmed that the coil having a lower efficiency and the series resistance Rw has a higher q. Here, by using the frequency fl of the full SRs > Rw It is better to increase the power transmission performance than the known technology. It is preferable to open the other coil opposite to one coil and set the equivalent series resistance of the square coil to Rn ( Ω ). When the highest frequency satisfying h GRw is set to f2 (Hz), & is set at an unreached frequency to operate the power transmission device.

When the outer diameter is set to 〇, the outer diameter D of the coil of the hollow core coil u is > is the maximum passing d^ 单 of the single wire 12, and the number of turns of the line π is a predetermined resistance number, for example, 8 or more and 2 3 degrees 2 When the guide shape is other than a circle, the shape of the coil: the two-replacement coil is that the minimum outer dimension map of the coil to the third map is at least 2# Η or more. Furthermore, the core of the core coil 1a from the coil body (four) " the frequency of the power of the air core is just the same as the equivalent of the other coil of the coil is shorted to the highest one at this time, one coil or the other coil is tied "".

The reason why the number of turns of the control = 11 is 8 or more is to obtain a self-inductance of 2 a Η or more.

At this time, the highest frequency satisfying rs > Rn ^ Rw is set to (Hz) One of the power coils or the other coil is driven by the AC power source Va at a frequency fd that is less than f2. In addition, the thermal resistance of the air-core coil 1 a is set to 0 i / W ), the allowable operating temperature of the air-core coil 1 a is set to Tw (t:), and the ambient temperature at the place where the air-core coil la is placed is set. Ta (£>c), when the alternating current flowing to the air-core coil 1a when the power is transmitted is set to la (A), the relationship of (Tw-Ta) / (ia2x0i) is satisfied when the air-core line la is transmitting power. . The air-core coil 1a, which is not configured as described above, can be used as the power transmission coil 1 or the power receiving coil 2 in which the 1 - human side coil and the secondary side coil shown in Fig. 1 are separable power transmission devices.

Further, according to the above circuit theory, as shown in Fig. 7, it is known that when the secondary side coil is short-circuited, the pure resistance value of the secondary side is increased to (μ + A2R2). Here, 'R2 is the equivalent series resistance of the secondary side coil. When Μ is set as the mutual inductance between the primary side coil and the secondary side coil ', 〇 is set to the angular frequency 2; rf'f is the frequency, Ηζ) , set 2 is set to: times; when the coil is self-inductive, A2=^mV (〇2匕22 money 22), 20, L22&gt;〇, R22&gt;〇' is therefore obviously A^〇. In the inductance of the primary side, if the self-inductance of the primary side coil is u, as shown in Fig. 7, it is known that when the secondary side coil is short-circuited, the inductance of the secondary side is reduced to -A2L2) . However, referring to Fig. 9 to Fig. 12, in the region where the frequency is high, the case where Rs is smaller than Rw can be seen. As can be seen from Fig. 9 to Fig. 5, the frequency at which Rs &lt; Rw is formed is about 67 kHz or more in the air-core coil 1A. The air-core coil 1B is approximately 2 〇 8 kHz or more. The air core coil (1) is approximately 82 octaves or more. In the air-core coil in which the enamel wire is wound by a flat plate spirally attached, as shown above, the thicker the wire diameter of the enamel wire, the lower the maximum frequency fl of the RS &gt; Rw is satisfied. Further, according to the ηth diagram, 319286 34 1331432, in the air-core coil 1D which uses the same single wire as the air-core coil le and is wound into a 3 OD outer diameter 30, the highest of Rs &gt; Rw is satisfied: f 1 Higher than the air core coil i C. ’, 卞 From Fig. 9 to Fig. 12, the increase in the equivalent series resistance of the air-core coil with the highest frequency R which satisfies the highest frequency of Rs&gt;Rw is also high. According to Fig. 15, even if the enameled wires of different diameters such as 〇2mm, 0.4mm, 〇.8, l.〇mm, etc. are formed as hollow core coils having different coil outer diameters of 25 under = area, The aforementioned characteristics are also the same. It can also be seen that the thicker the wire diameter of the enameled wire, the higher the rate of increase of the equivalent string lightning with the increase of frequency. Further, it can be seen that in the coil wound with the same wire diameter, the number of windings is small and the outer shape is small, and the coil has a higher ancient frequency fi satisfying Rs &gt; Rw, and the equivalent series resistance R is also caused by the frequency rise. small. In other words, if it is in accordance with the circuit theory, it must be full of sRS>Rn=R relationship', but the null _1A to the air-core coil 1D is used to form the variable device + as shown in Fig. 6 and Fig. 7, In the higher frequency region, the relationship of RS &gt; RW is not satisfied. For example, in the air-core coil ib, as is understood from the first diagram, Rs &lt; Rw is formed at a point having a frequency of 2 〇 8 kHz or more. In the frequency region where the relationship between Rw and Rs is Rs &lt; Rw, the positive A2 will become negative. In Figs. 9 to 12, the actual value of the commutating resistor RUR2 shown in Fig. 8 cannot be obtained in the frequency region where RS &lt; Rw is formed. The examples are shown below. In the basin, since the equivalent coefficient is approximated by the equivalent series resistance, the light-weighted number is 5 匕. As will be described later, the coefficient (4) calculated by the inductance is marked as 319286 35 1331432 • ki. • According to the known circuit theory, if the coupling coefficient is set to kr, the mutual inductance is set to 馗, will! When the self-inductance of the secondary coil is L1 and the 'from f' of the secondary coil is L2, the relationship of M2=kr2·LI·L2 is established. If the same coil is used for the primary side coil and the secondary side coil, since R1==R2 and L1=L2' are formed, when 〇2l22&gt;&gt;R22 is satisfied, α2=0, 2 / C ^2L22+R22 is obtained. ) = ω2Μ2/ ( W2L22) = kr2 · Ll/L2 = This, from (R1 + A2R2), forms (Rw + kr2Rw) with kr 5 (Rs - Rw) / Rw *, approximates y, and is satisfied &gt;TCC Rs Rw) / Rw). : 中―'About whether the heart is satisfied or not, if it is the same coil, since R1 = R2, L1 = L2, yLiVRw2 is calculated, and the value of the (four) combination coefficient is judged as the error at the 50th or more - at the 9th In the figure to the 12th, 16th, and 17th, _ to 30kHz or more, then ^liVRw2&gt;5() ^ 2 k rate area, as above, f gentleman d Rs> Rw^^ V RW, Rs approximate to obtain the light-combination coefficient. However, in the frequency region where Rs &lt; RW is formed, the bins are merged into a bin, and the τ... A/Bema positive A2 becomes negative. The coupling coefficient 匕 can be squared. =: two and seeking (four) combination coefficient = before the big brother 8 picture, and can not find ri, r if RS = Rw 'light combination coefficient kr will become zero, when Rs < r, only the value. Learning, The light-coincidence coefficient Jcr will become an imaginary number. In fact: 'There is a mutual mutual inductance M $ M Yin 〇, but ^ is relatively zero or imaginary 36 319286 Ϊ 331432. It is theoretically impossible. In the frequency region where the condition of Rs &gt; Rw is not satisfied, as described above, the values of the series resistances R1 and R2 are unknown. Further, the coil 丄: effect: the coupling resistance R w becomes large, that is, The current J flows to the i-second side and the second-order side (fourth) circle. The power loss caused by the (4) 2 and the coffee 2 will cause the overheating of the hot plate. Because of this power loss, the effective power transmission efficiency is reduced. The same coil is used on the primary side and the secondary side. When 2:R; = Rs, the light combination coefficient ^ becomes i, so the heart can be used. First, the air core coil 1A is used in one (10) comparative example. To explain the air core coil: use both the t-square coil and the other-side coil. At this time, according to Fig. 9, the second highest frequency, 1A satisfies the highest frequency (R) of Rs &gt; Rw is about 67. , ========================================================================================================= The same power transmission performance of the coil of Comparative Example 1 is carried out. The ratio described in Japanese Patent Laid-Open Publication No. Hei No. Hei. No. 7 is the winding of a 1 mm enamel single copper wire 25 times: : plate and spiral shape' The inventor of the present invention is substantially the same as the empty material ring 1A. The inventor of the present invention satisfies the air core coil 1A with Rs &gt; Rw ^ inch open 2-4-122007 Seoul described as a power transfer frequency "and into the Ding additional testing. When the opposing distance between the two coils is zero, the effective power of about i〇w can be transmitted to the non-inductive resistance of the sensible 319286 37 1331432 1 connected to the power receiving coil. It is possible to confirm the power transmission performance of one of the power transmission performances described in Comparative Example 1 of Japanese Laid-Open Patent Publication No. Hei 4-122007. In the Japanese Patent Publication No. 4-122007, the same coil is used for the secondary side coil and the secondary side coil. Therefore, the air-core coil 1A shown in Fig. 9 of the present application is used as one coil, and the air-core coil 1F shown in Fig. 16 which will be described later is used as the other coil. As a result, the highest frequency fl of the air-core coil 1A satisfying at least Rs &gt; Rw rises from 67 kHz to 1 丨 0 kHz. As a result, the power transmission performance can be improved more than the comparison described in Japanese Patent Laid-Open No. 4-122 G G. Therefore, even in the air-core coil 1A of Fig. 9, by selecting the opposite coil, the power transmission performance can be directly improved by the air core without using a magnetic material or the like. Secondly, according to the actual test, regarding the air-core coil 1A, the stop of the Rs&gt;h=frequency is the air-core coil 1AHf in the opposite coil, according to the figure 9 &quot; Z, when the opposite coil is the air-core coil 1G, Although not shown in Figure j, it is 15. By selecting the opposite-side coil, the highest frequency η of the conditions of ..., amRs&gt;Rw is increased. The factory makes the air-core coil 1A and the air-core coil 1F

In the area, the air-core coil 1A and the air-core coil IF both satisfy Rs>Rw. That is, the comparative example described in Japanese Patent Laid-Open No. Hei 4-122007 is for power transmission. Both the coil and the power receiving coil use substantially the same coil as the air core coil 1A. At this time, the highest frequency Π of the condition that the air core coil 1A satisfies Rs &gt; Rw is about 67 kHz. The air core coil 1A and the air core coil are used in combination. 1F, even if the air core coil is used in the power transmission coil, receiving power In any case, it is also possible to transmit power at a frequency of 67 kHz. It is also possible to improve the power transmission performance in the 50 kHz described in the comparative example i described in Japanese Patent Laid-Open No. Hei 4-222007. When the air core coil 1A and the air core coil U are used in combination, the fl of the air core coil is increased. In the present invention, when the fl of the square coil is low, the Π of one coil is selected to be higher than a predetermined frequency (for example, l The coil of 〇〇 kHz) is used as the other coil. The green coil selected as shown above is combined with the other coil to form a power transmission device. The configuration described above can be used at a higher frequency. Coil. Moreover, the power transmission performance of the power transmission device is also good. First, select one coil and the other coil. Measure the frequency characteristics of RW, Rs, and Rn in the - square line. According to the measurement data, know, The circle satisfies the highest frequency fl of Rs&gt;Rw. The frequency characteristic of the power transmission performance is 319286 39 丄&gt; by the second diagram of the coil combination of the horse, and then the output frequency fa of the AC power source is set to less than fl. .Such as Power transmission devices with excellent power transmission performance are not available. ^The coils 15 to 1D with single wire, the full HS> RW: the other: more than 100 kHz. The coil 1 is (1) as the square coil, and the other - the square coil is used as the coil 1B to the middle, and the highest frequency that satisfies RS &gt; RW = any = is obtained. The square coil includes the six', and the output frequency of the power transmission device 乂m original Va is exempted as It is not possible to achieve a power transmission device with excellent power transmission performance as above. &gt; Rn ^ sink satisfies the case of RS &gt; Rn^RW, and the difference in W^ shape in the Rs ring unit is not satisfied. As mentioned above, 'in the empty anger line # constituting: the equivalent series resistance Rw is correctly obtained for the measurement, ': the variable order shown in Fig. 6 is as shown in Fig. 9 to 13 = no Only the secondary coils are opposite each other, and in the higher frequency region, the magic is 5^ to Μ.

Here, in the air-core coil 1F, the coupling coefficient kr is about 〇9 when it is 1 〇〇 kHz, and decreases as the frequency increases, and decreases to about 〇65 in 1 MHz. Therefore, it is preferable to change the frequency of RS &gt; RngRw as high as possible. The coil is used in the frequency region satisfying the condition of RS &gt; RGRW, so that the coil unit of Fig. 5 and the variable arrangement shown in Fig. 6 are close to the theoretically ideal characteristics.

In the respective embodiments of the present invention, the electric power between the two coils is realized by the air-core coil which is not provided with the magnetic material, and in the state of the sparse rotation of about 0.9 or less. It is difficult to carry air cores that can transmit large power, such as: As described above, although the power factor is 〇5 or more, the ineffective power of the slanting surface into the primary side coil sometimes exceeds the effective power. When the power factor is reduced from 1 to 0.5, the loss caused by the equivalent series resistance Rw of the W coil is doubled by the fact that the electric power f to the coil is doubled. Moreover, when the current flows to the negative interceptor connected to the coil of 2 times 44 319286 1331432 • I, the resistance is %, and the current flowing to the secondary coil is generated, and the magnetic flux will be formed once. The wire of the side coil generates eddy current loss, and the primary side coil generates heat. Therefore, the inequality RW$ ( Tw - /( X Θ i ) preferably satisfies the practice of the present invention, and if it is not satisfied, it is difficult to implement the present invention. a, wherein, in the frequency of transmitting power, if Rs &gt; Rn2Rw is satisfied, In Fig. 38, if the internal resistance R3 of the power supply is equal to or less than Rw, the secondary side coil viewed by the load resistor is short-circuited as the secondary side. gj This R2 is substantially equal to Rs. Therefore, it is preferable to satisfy Rs$ (Tw_Ta) / 犄 in the 1st-order side coil. Further, in Fig. 38, although the value of R1 is unknown, it is satisfied in the primary side coil. Rs$ (TW—Ta) / (ιΛθυ is better.

In the coil, since the phase of the I is slower than the phase of the V by 9 degrees, the moment of V is When the one-time integration is multiplied by the instantaneous value of I, the power becomes zero. Therefore, the coil as the reactive element does not consume power. In this field, the leakage flux occurs and energy loss occurs. The literature on the improvement of the flux-to-chain ratio 'the shape of the coil has been seen, but as mentioned above, the leakage flux does not consume power. 45 319286 Π31432 * Therefore, assume that the equivalent series resistance Rw is small enough There is no ratio of the leakage flux, and the degree of the privateness of the 'opening' is as follows: Patent No. 8: Transmitting large electric power.

In FIG. 2A, although a single-cone 12 is used as a circular cross-section, it is possible to use an insulating coating 13a applied to a single-conductor 12a having an elliptical cross section as shown in FIG. 18A, or as shown in FIG. 18B. In the example of the figure, the insulating member 13b is applied to the single wire 12b having a polygonal cross section. In this example, the insulating covering members 13a and 13b may be either a thin but strong covering member such as a stencil wire or a coating thick like a vinyl wire. 319286 47 U0U32 . However, in Figs. 18A and 18B, the line indicating the maximum outer diameter dl • is preferably parallel to the surface of the wound wire. This is also the same in other embodiments of the present invention. Further, when the adjacent wires are closely connected, it is preferable to determine the direction of the cross section with respect to the winding surface in such a manner that the "joint of the line is a point." The 19th ® is a cross-sectional view of a coil in which a wire is wound into a cross-section umbrella type. The air-core coil shown in Fig. 2A "winds the wire u into a flat core single-layer spiral shape. On the other hand, the air-core coil ratio shown in Fig. 19 is formed such that the = surface becomes an umbrella type. It is a single-core spiral of air core. The winding width of Figure 19 is D1, the inner diameter is j)2, and 2χ D1 + D2 is the condition of the maximum outer diameter of the wire & 25 times or more. The angle 0 of the line showing the two winding widths D1 is preferably set between 180 degrees and 9 degrees. However, in the 19th figure, the winding width m ^ is: D2 t is about 1/4 or less. Moreover, when the short-circuited coils are opposed to each other, if the above Rs &gt; Rw is satisfied, a spiral shape of 0 close to zero can be formed. # - Figure 20A is used to wind the hollow core of the sectional umbrella type as shown in Fig. 19. The magnetic field strength of the coil ib is compared with the magnetic field strength of the air-core coil 1a of the cross-sectional plane type shown in Fig. 2A. As shown in Fig. 2B, the air-core coil u shown in Fig. 2A is in the plane. The strength of the magnetic field at the position will become stronger at the central portion and the strength of the magnetic field will become weaker. In contrast, in Fig. 20A, the winding shown in Fig. 19 is shown. The magnetic field strength at the plane position when the air-core coil ib of the profiled umbrella type is opposite to the upper and lower sides. As shown in Fig. 2, the air-core coil lb that is wound into a profile umbrella type can be roughly obtained on the entire surface of the coil surface. Uniform magnetic field strength 319286 48 丄川432 In addition, the hollow core coil lb can also be wound and wound in the form of a wave line. The external image is a cross-sectional view of the coil wound around the insulating material. The air-core coil 1a shown in Fig. 2 is disposed on the insulating material 5, and the insulating resin 6 is applied to the single conductor 11 of the air-core coil la. In this case, the insulating member is insulated. The resin 6 is filled in between the wires i! and is fixed so that the hollow core coil la can be prevented from being deformed. It is also possible to replace the aluminum coil 5 on the insulating material 5 with an adhesive. By the configuration of the above, the thermoelectricity (4) i can be reduced, and the coil heat can be suppressed. 'Specifically, an insulating material 5 of about 5 mm is placed between the two coils, even if it is on the 1st side and 2 times. There is a potential difference of about 10,000 volts between the sides, which will not cause problems. The thermal resistance is lowered to reduce the heat of the coil. Therefore, a large power can be transmitted. FIGS. 22A and 22B are diagrams showing the air core coil of the power transmission device of another embodiment of the present invention, and FIG. 22A is a diagram showing In plan view, Fig. 22B is an enlarged view showing a section along line 2b_2b of Fig. 22A. In the embodiment shown in Fig. 22B, a single wire 12 having a maximum diameter di of 0.4 mm or more in a single wire is applied. The wire 11 having the insulating covering member 13 is wound into a spiral shape of a flat plate, and as shown in the figure, a gap t of two or more faces is provided between the adjacent wires U of the air anger coil lc. Unwinding. In this example, the insulating covering member 13 may be a thin but strong covering member such as a fonnal wire, or a coating member such as a vinyl wire thick. Further, since 319286 49 ^^1432 is provided with an empty 35t between the adjacent wires 11, a bare wire to which the insulating-edge covering member 13 is not applied can also be used. When the maximum outer diameter dl is less than 〇·4_, the gap of dl/2 is set. In the present embodiment, the wires of the real surface state described later are also the same, and the maximum outer diameter dl is denoted by d. In the present embodiment, the air core coil 1C is configured such that when the outer diameter of the coil is D, "at least the outer diameter D of the coil is more than υ times the maximum diameter di of the single wire 12" and the number of windings of the wire 11 is 8. the above. In addition, it is conditional to satisfy the self-inductance of the air spring ~ coil 1 c at least 2 # H or more. In addition, the equivalent series resistance of the air core coil 丨c in the frequency at which the power is transmitted is set to Rw (Q), and the two air core coils U shown in FIG. 22A are opposed to each other and will be opposite to each other. When the other line of the coil is short-circuited, when the equivalent series resistance is set to (8), if the frequency of satisfying Rs &gt; Rw is set to n ', the square coil or the other coil of the power transmission coil is not reached. The frequency fd of fl is driven. In addition, when the relative resistance of the other coil in the frequency of transmitting the power is turned on, the equivalent series resistance of the other coil is set to Κη (Ω) = 'right will satisfy the highest frequency setting of Rs &gt; Rn^Rw In the case of f2, the square coil or the other coil as the transmission coil is driven at a frequency fd which is less than f2. In addition, § set the thermal resistance of the air-core coil 丨c to θ丨(/w), = the allowable operating temperature of the air-core coil le to Tw(t:), and the ambient temperature at the place where the vacant coil c is to be placed. It is set to D &amp; ( ^ ), and the AC current that is caught to the air-core coil lc when transmitting power is set to (4) 胄, that is, the relationship of Rwg (Tw-Ta) / (Ia2x Sichuan is satisfied. 319286 50 丄丄. In Fig. 2B, when the poor junction is 仏 + • the magnetic flux generated by the current.:; two =, due to the wire flowing in the Φ θ bei tooth adjacent to the wire, the eddy current occurs in the phase wire, And because the current is affected, the equal current is caused to increase the m-connected resistance RW flowing in the wire. In the fourth embodiment of the present invention, an air barrier is provided: thereby, due to the adjacent one-sided wire The magnetic flux 1 generated in the vicinity of the current flowing through the current does not pass through the adjacent guide, and the spring is suppressed by the magnetic flux Φ passing through the adjacent ¥ line. Eddy current loss occurring in the connected wire. Since the eddy current loss increases in proportion to the frequency, it is adjacent A gap is provided between the connected wires to prevent an increase in the equivalent series resistance Rw due to an increase in frequency. Among them, the magnetic flux 1 near the wire u is strong, and slightly away from the wire U, the magnetic flux Φ is rapidly weakened, so even a small gap is It has the effect that the gap width can be expanded to any size. However, if it is too large, the number of times of winding 8 times cannot be ensured or the self-inductance of the coil is 2/ζΗ or less. 9 shows the equivalent series resistance Rw of the closed core of the hollow core coil 1 and the frequency characteristic of the equivalent series resistance of the coil of the hollow core coil 1 shown in Fig. 14 Fig. 23 shows that when the frequency rises, the unwound hollow core coil 1E can suppress the increase of the equivalent series resistance of the coil compared with the closely wound hollow core coil 1A. In the coil, since the total length of the winding is shortened, the DC resistance can be suppressed to be low. Fig. 24 shows that when the 漆4 mm enameled wire is wound into 25 turns, the frequency characteristic of the equivalent series resistance of the coil depends on Difference in gap width As 31,928,651

One by one, the resistance of the operation / see the I gap can suppress the increase of the equivalent series resistance accompanying the rate of loading. Among them, the -r W electric life width, 绫 &amp;, and the number are formed the same, so the outer diameter of the gap width coil is larger, and the total length of the copper wire constituting the coil becomes longer, so in the (four) rate, the equivalent series resistance If you do not set a gap =. Since the eddy current loss is caused by the volume of the conductor through which the magnetic flux penetrates, if the maximum diameter of the single wire is not more than 02 mm, even if the space and the gap t are provided between the wires, the increase rate of the equivalent series resistance of the coil due to the frequency rise is Will not fall so low. The relationship between the frequency of the air-core coil unit and the equivalent series resistance of the intestine made of the m-wire winding diameter of mm is also known as the wire diameter 〇2mm, due to the frequency increase (four) effect series electricity (4) The increase rate will be less. 'If the single wire of the wire diameter 2.2 depends on the gap, the frequency characteristic of the equivalent series resistance Rw is not improved. The self-inductance of the coil 1D having an outer diameter of 30 mm was made to be approximately the center H by using a single wire having a wire diameter of 3 mm as shown in Fig. 12 and winding into a 31 # region. The self-inductance of the coil in which the coil 1D is wound into a double layer is about 7_H, and the obtained result is compared with the self-inductance and (four) flat; the material A of the JL ratio is (4). The frequency characteristic of the series resistor is smaller than that of the single layer winding, and the southmost frequency fl satisfying Rs &gt; Rw is also low. However, in the low-frequency region where the equivalent series resistance is low, since the reactance can be ensured, there are cases where a double-layer winding is formed and the user is advantageous at a low frequency. Among them, a coil in which the coil 1D is wound in two layers is used in one coil and the other coil. The coil formed by winding the coil 1D in two layers satisfies 319286 52 1331432

Rs&gt;Rw之最高頻率為550kHz，由於電感較高，因此即使 .以未達250kHz的頻率來使用，亦可確保所需要的電抗。 - 於第15圖中，將線徑G.2mm的單導線予以密繞時， 在5kHz的等效串聯電阻^為〇83Ω。在1MHz的等效串 聯電阻為2.16Ω，且等效串聯電阻的增加率為216/〇83 =2_60,小於將後述之線徑lmm之單導線設置空隙而捲繞 成的空芯線圈1E的增加率7.6。但是，在線徑〇 2111111的空 芯線圈中，由於RW的絕對值會變大，熱電阻會變小， 因此必須選擇適合所傳送之電力值的導線徑，以滿足Rw S (Tw-Ta) / (la2x0i)的關係。 以下參照第14圖說明作為本實施形態之一例之空芯 線圈1E的特性。於空芯線圈1E中，雖使用直徑imm的 漆包線’但是可知在5kHz至約3 7MHz之間，滿足Rs &gt; Rn = Rw的條件。觀看第2 3圖可清楚得知，即使使用完全 相同的漆包銅線，藉由設置空隙來繞線，使因頻率上升造 _成的等效串聯電阻的增加率明顯改善。 由於由圖中難以讀取，故以具體數值表示。5kHz時之 空芯線圈1A的RW約為〇.〇8 Ω，空芯線圈1E的Rw約為 〇·〇5Ω。1MHz時之空芯線圈ία的rw約為3 8Ω，空芯 線圈1Ε的RW約為〇38Ω。若由因頻率所造成的增加率來 看在空4線圈1Α為3.8 Ω / 0.08 Ω = 47.5，在空芯線圈 1E為0.38 Ω/〇.〇5 Q = 7.6。如上所示，空芯線圈1E單體 的等效串聯電阻Rw的頻率特性大幅獲得改善，即使為高 頻率’由於等效串聯電阻Rw較低，因此若使用空芯線圈 53 319286 1331432 1E，即可以高頻率來傳送電力。由於上述實施形態的線圈 之等效串聯電阻R w在寬頻率範圍較低、滿足R s &gt; R n ^ r w 的最高頻率f2亦較高，因此電力傳送特性佳。The maximum frequency of Rs&gt;Rw is 550 kHz. Due to the high inductance, even if it is used at a frequency of less than 250 kHz, the required reactance can be ensured. - In Figure 15, when a single wire with a wire diameter of G.2 mm is tightly wound, the equivalent series resistance at 5 kHz is 〇83 Ω. The equivalent series resistance at 1 MHz is 2.16 Ω, and the increase rate of the equivalent series resistance is 216 / 〇 83 = 2 - 60, which is smaller than the increase of the air-core coil 1E wound by a single-wire gap having a wire diameter of 1 mm to be described later. Rate 7.6. However, in the air-core coil of the wire diameter 1112111111, since the absolute value of RW becomes large, the thermal resistance becomes small, so it is necessary to select a wire diameter suitable for the transmitted power value to satisfy Rw S (Tw-Ta) / (la2x0i) relationship. The characteristics of the air-core coil 1E as an example of the present embodiment will be described below with reference to Fig. 14. In the air-core coil 1E, the enamel wire ' of the diameter imm is used, but it is understood that the condition of Rs &gt; Rn = Rw is satisfied between 5 kHz and about 37 MHz. It can be clearly seen from Fig. 2 3 that even if the same enamel-coated copper wire is used, winding is provided by providing a gap, so that the increase rate of the equivalent series resistance due to the frequency rise is remarkably improved. Since it is difficult to read from the figure, it is represented by a specific numerical value. At 5 kHz, the RW of the air-core coil 1A is approximately 〇.〇8 Ω, and the Rw of the air-core coil 1E is approximately 〇·〇5 Ω. The rw of the air core coil ία at 1 MHz is about 38 Ω, and the RW of the air core coil 1 〇 is about 〇38 Ω. If the rate of increase due to frequency is seen in the empty 4 coil 1 Α is 3.8 Ω / 0.08 Ω = 47.5, in the air core coil 1E is 0.38 Ω / 〇. 〇 5 Q = 7.6. As shown above, the frequency characteristic of the equivalent series resistance Rw of the single core coil 1E is greatly improved, even if it is a high frequency 'because the equivalent series resistance Rw is low, if the air core coil 53 319286 1331432 1E is used, High frequency to transmit power. Since the equivalent series resistance R w of the coil of the above embodiment is low in the wide frequency range and the highest frequency f2 satisfying R s &gt; R n ^ r w is also high, the power transmission characteristics are excellent.

In addition, the 'inductance is not described in the Japanese Patent Publication No. 6_29ιΐ7, but the self-inductance of the air-core coil π in 1 MHz is about 6.MH, the reactance Xi is about sen, and the equivalent series resistance Rw is about 〇.

In the wire nd shown in Fig. 28A, the ratio of the cross-sectional area of the conductor 15 to the sectional area of the insulating covering member 16 is determined by the wire diameter or the wire. Since the number of conductors of the crucible is determined by the number of conductors, etc., the conductor jld is constituted by an assembly (e.g., seven single conductors 8) to which the insulating covering members 16 are respectively applied. When the maximum diameter of the conductor 15 other than the insulating covering member 16 is d4, it is preferable that the thickness of the insulating covering member is "(d4) / 3 〇 or more. Since the air layer other than the insulating covering member 16 is also an insulator layer, it is considered that as shown in Fig. 28A, (4) the smallest circle containing 7 single wires 8, and 7: two rounds of the first six (four), if the above-mentioned regular hexagon is calculated When the area and the total cross-sectional area of the body i1 body 15 are the same, the ratio of the edge layer of the wire to the air layer is about 11%, which is as shown in Fig. 27.

This: When the power is to be transmitted The one of the relative relative coils in the frequency is:: the equivalent series resistance of the other coil is set to Rn (Q). The highest frequency of the wire H /> RQRW is set to f2, and is driven as a drive. In addition, when the thermal resistance of the air-core coil le is ΘΚΪ =, the allowable operating temperature is Tw (t), and the ambient temperature of the empty space is Μ), When the AC current of the transmission power to the four coils is set to ^(4), Rwg (Tw - Ta) / (Ia2x0i) is satisfied by Η.

Even if the Li gap is wound into a flat single-layer spiral, the Rw (four) rate characteristic of the air core coil unit is not improved, and conversely, the self-inductance of the core coil unit is reduced. Between the enameled wires: the mutual inductance between the wires, and the change in self-inductance when formed as a coil. 2, according to the 搓捻 method or 搓捻 spacing, burning line (close winding, entanglement, 曰 曰, v 〇 line) 'E number, shape, etc., and make the characteristics change. The wires used in the air core coil 1F shown in Fig. 16 and the air core wire 1G shown in Fig. 17 are the same as the outer diameter of the conductor 〇〇5 mm and the thickness of the insulating coating member is 0.05 mm. The Litz wire 'air core coil 1F which is bundled with 75 wires with an outer diameter of 〇〇6 faces is densely wound around 3 times to have an outer diameter of 70 mm, and the hollow core coil 1G is wound twice to become an outer diameter. 5〇mm. If the frequency characteristics of RW, Rn, and Rs of the air-core coil and the air-core coil 1G are compared by using Figs. 16 and 17 , the point where Rs &lt; Rn is formed in the air-core coil is 78 〇. kHz or more, but in the air-core coil 1G, the condition of Rs&gt;Rn^Rw is satisfied up to about 2.1 MHz. The reason cannot be determined whether it is related to the 搓捻 mode or the 搓捻 spacing, or 319286 60 1331432. The resistance or shape and the winding method are related. However, if at least the frequency characteristics of the Rw, Rn, and Rs of the coil are measured, it can be judged whether the coil is applicable to the power transmission device. The specific method is as follows. The first system describes the air-core coil 1B, the air-core coil 1F, the single-body inductance Lw of the air-core coil 1G, and the inductance Ls of the same air-core coil that is short-circuited with respect to zero in the respective frequencies from 5.0 kHz to 1.0 MHz.

As described above, when the self-inductance of the coil in Fig. 5 is set to Lw (Η) and the inductance of the primary side coil in Fig. 6 is set to Ln (Η), 61 319286 1331432 is shown in Fig. 5, In the picture of the younger brother, the relationship of L1 = Lri is established, as shown in Fig. 7, when the short-circuit of the secondary side is short-circuited with the secondary side coil of the side of the side of the side When the component is set to Ls(H), the relationship of ^(1) - Ah) is established. It is not the same as the equivalent series resistance, and u = Lw = Ln is also formed after the actual measurement. The u, L2, and a2 are as described above. When the same coil is used on the primary side and the secondary side, since L1 = L2 and R1 = R2', Ls=(Lw~a2Lw) is established, and if it is 5嶋 to 100kHz or more, ^L2Vr2, 5〇 or more Therefore, it is regarded as A and ]α2. So formed! ^= (Lw—Ls)/Lw, ki=/(

Ls) /Lw)，而近似求取耦合係數ki。如前所述，將如 上所示由電感之變化Lw、Ls所求出的耦合係數標記為ki。 若將標繪在第16圖及第17圖的匕及ki相比較，可知於 第17圖中，kr及ki係大致一致。 然而’在第16圖中，並未見到kr及ki 一致。此外， 以比較例而言，於空芯線圈1B中，在第n圖、第12圖 _雖標繪有前述kr及前述ki，但是於第12圖中可知以成為 Rn &gt; Rs之頻率為界，kr係急遽減少。實際上，當使用2 個第17圖所示之空芯線圈1G時，由於至2 1MHz為止均 滿足Rs&gt;RngRw、至ιοΜΗζ為止均滿足Rs&gt;Rw，因此 可利用高頻率、高電力因數、高有效電力效率來傳送電力， 且電力傳送性能非常好。 亦即，滿足Rs &gt; Rng Rw之最高頻率f2較高，若為高 頻率，Rn/Rw的值愈接近1則線圈·性能愈佳，因頻率上 升導致Rw的增加亦較少。如上所述，藉由觀察頻率及 62 319286 1331432 二：Rn、Rs的闕係、或者藉由將由Rw與心求 率特性相與^求出之衫係數ki的頻 z= 二可得知僅以空芯線圈單體之等效串聯電阻 =頻率^並無法判斷之使線圈相對向之作為電力傳送手 &amp;的變篁器的性能。 Η距㈣Λ 、線圈之李兹線的適當搓捻方式或搓捻 %線方式係當形成複數個線圈，且測量線圈的Rw、Ls) /Lw), and approximate the coupling coefficient ki. As described above, the coupling coefficient obtained by the inductance changes Lw and Ls as shown above is denoted as ki. Comparing 匕 and ki plotted in Fig. 16 and Fig. 17, it can be seen that in Fig. 17, kr and ki are substantially identical. However, in Figure 16, no kr and ki are consistent. Further, in the comparative example, in the air-core coil 1B, the kr and the ki are plotted in the nth and twelfth drawings, but in the twelfth figure, the frequency of the Rn &gt; Rs is In the world, kr is in a hurry. In fact, when two air-core coils 1G shown in Fig. 17 are used, since Rs&gt;RngRw and ιοΜΗζ satisfy both Rs&gt;Rw up to 2 1 MHz, high frequency, high power factor, and high can be utilized. Effective power efficiency to transmit power, and power transmission performance is very good. That is, the highest frequency f2 satisfying Rs &gt; Rng Rw is high, and if it is a high frequency, the closer the value of Rn/Rw is to 1, the better the performance of the coil, and the increase in Rw due to the increase in frequency is also small. As described above, by observing the frequency and 62 319286 1331432 two: Rn, Rs, or by the ratio of Rw and the heart rate characteristic, the frequency z = 2 of the shirt coefficient ki can be obtained only by The equivalent series resistance of the air-core coil unit = frequency ^ can not be judged to make the coil relatively opposite to the performance of the power transmission hand &amp; Η ( (4) Λ , the appropriate 搓捻 mode of the Litz wire of the coil or 搓捻 % line mode is to form a plurality of coils, and measure the Rw of the coil,

This method is not limited to the Litz wire. It can also be applied to a single steel wire, a urethane baseline, or a wire of another embodiment to be described later, and a coil suitable for power transmission can be selected. That is, by changing the wire, the wire diameter, the size, the shape, the winding method, etc., it can be judged that the frequency characteristic of the equivalent series resistance of the single-core coil unit alone cannot be judged to cause the coil to be relatively transmitted as power. The performance of the variable device of the means can provide a coil with good power transmission performance that cannot be realized by conventional techniques. For example, since the air-tolerance coil 1E in which a single conductor of 1 mm is used and the gap is wound up to 3.7 MHz is satisfied to satisfy Rs &gt; RngRw and to 7.7 MHz, it satisfies RS &gt; Rw ', and therefore, compared with the air-core coil 1G, The rules of RS &gt; Rn2RW are not much different. However, the RW of the air core coil 1E in 4 MHz is 〇.87Ώ, and the Rw of the air core coil 1G unit is about 2 Ω; the Rw of the air core coil 1E in 10 MHz is 2 9 Ω, the air core coil 1G The Rw of the monomer is 17 Q, and the high-frequency characteristic of the equivalent series resistance Rw of the coil unit of the hollow core coil 1E is better than that of 319286 63 1331432 compared to the hollow core coil. Therefore, 'by Rw $ (Tw—Ta) / ( Ia2x 0 i ), the air-core coil IE formed by a single wire can be higher than the frequency of the air-core coil 1G formed by the Litz wire. To use. As described above, the present invention is a hollow core in which Rs &gt; Rw, Rs &gt; Rn g Rw, Rw g ( Tw — Ta ) / ( Ia2x θ i ) are not realized by conventional techniques. Since the coil is provided with a frequency region which is most suitable for use of the coil, it is possible to realize a power transmission device having excellent power transmission performance as compared with the prior art, and achieve excellent effects. In the prior art including the above cited documents, only the specific configuration of the coil is specified. Next, by showing only one embodiment of a specific configuration, it is claimed that the emphasized characteristics, such as the frequency characteristics of the equivalent series resistance, have been improved. However, as described above, even if the outer diameter or the inner diameter are formed to be the same, the characteristics of the coil are completely different depending on the wire diameter and the number of turns. In addition, even if the same wire is used, the characteristics of the wire loop will be different when the composition (outer diameter, number of turns, etc.) is different. That is, even if a specific configuration such as a wire or a winding method is specified, the coils actually produced have various configurations, and there is no guarantee that the coils achieve the same effect. Therefore, only the specific configuration of the coil is specified, and it is impossible to realize a coil having a sufficient component as a coil of the power transmission device. At present, the power transmission of the power transmission of Xiao Power, which can be effectively transmitted at 8 G% as described in the Japanese Patent Laid-Open Publication No. 122-7, has not yet been implemented. As shown in the present application, the change in the characteristics when the configuration other than the specific configuration of the coil is changed to 64 319286 I33l432 is clarified, and the coil having the power transmission performance cannot be realized as long as the operation strip of the coil is not specified. Power transmission performance is good. On the other hand, the present invention is directed to a coil having various configurations capable of sensing, and stipulates operating conditions of each coil, whereby a power transmission device having excellent power transmission performance can be realized. As described above, the present invention achieves It is not known that the technology is extremely excellent. The coils of the power transmission device of the other embodiments of x ', 30, 31, 32, 33a to 3 are empty = in the tube = = edge material 18, when the tube 1 is in the middle, the mu can not be processed. The bending process. When the tube "tr or the thick wall of the tube" makes the tube itself portable, it is shown on the insulating material 19 to form a conductor. ,! In the drawing, the insulating material 21 is divided to form a conductor. The inside of the material 21 also forms a conductor. The two-section material j Puyi® is the (four) conductor and insulation material overlap, the line. That is, the guide member 25 is formed in the same manner as the first embodiment, and the box-shaped conductor 24 and the insulating member 24 and the insulating material 25 are fed into a lung, and the laminated foil-shaped conductor is spirally wound. % 'formed as shown in Fig. 33C is a section from Fig. 3D to Fig. 32, although there are 319286 1331432 on the circumference of the single conductor constituting the wire, and there is a conductor layer 'except that the insulating layer is applied or not applied to the conductor layer The article 'may be any as long as it is suitable for the embodiment as described. As described above, FIGS. 30 to 32 are embodiments in which an insulating layer is provided inside the conductor forming the coil, and the insulating material is provided with an insulating layer inside the wire, and the wire is made flexible, and the wire is easily bent. By. In addition, the air layer existing in the wire formed by bundling the single wire shown in FIG. 28A, and the air layer existing in the coil profile when the wires shown in FIG. 28A and FIG. 30 to FIG. 32 are multi-layer wound Also considered as insulation material. In the embodiment of Fig. 28A and Fig. 30 to Fig. 32, the surface area of the conductor constituting the wire can be increased, and the eddy current loss due to the magnetic flux penetrating the conductor increases in proportion to the volume of the conductor. Therefore, since the conductor volume of the magnetic flux path existing in the conductor passing through the conductor can be reduced, the increase in the equivalent series resistance Rw due to the skin effect and the eddy current loss can be prevented. The embodiment of Fig. 28A and Fig. 30 to Fig. 32 is merely an example in which the conductor constituting the wire is divided and the insulating layer is provided inside the wire. Of course, there are other embodiments, and it goes without saying. Each of the above-described coils is used not only as a power transmission coil or a power reception coil in a separable power unit but also as a transformer (variable transformer) in which two coils are inseparable. In the air-core coils of the above-described embodiments, it is not necessary to use the same air-core coil as the primary-side coil and the secondary-side coil in each embodiment, and the hollow core coil ia shown in the embodiment of FIG. It is also possible to use 66 319286 1331432. Air core coils with different numbers of turns or different shapes are used as the secondary side coil, the secondary side coil, or the air core coil of the embodiment of Fig. 2A] and the implementation of Fig. 22A. The form of the air core coil 〗 C is combined. The winding ratio can be arbitrarily set by forming the configuration as described above. Next, a power transmission means for the air core coil that can be used for boosting and stepping down can be realized. In the above case, Rw is measured by each air core coil unit, and Rn and RS are used to make the two coils face each other, and the coils are measured in each coil as long as it is confirmed to be full; I Rs &gt; Rw, Rs &gt; Rn ^Rw's relationship can be. By observing the frequency characteristics of Rw, Rn, and Rs in each of the primary side and the secondary side, it is predicted that the power transmission performance when the two coils are combined is as described above. Alternatively, a plurality of different types of coils may be produced, and in each of the coils, the same-coil is used to measure the frequency characteristics of the core, and the coils with good characteristics are used in combination. After the combination, it is more preferable to measure the frequency characteristic of the core in the secondary side coil and the secondary side coil. Next, the coil is recorded 8 times and the lowest value of the inductance is 2#h. The coil described in Japanese Laid-Open Patent Publication No. Hei 8-148360 is recorded five times. The Lw of the coil in 1 MHz is 〇 79 # H, and Ls is 〇 45 private η.

Further, the aforementioned coil satisfies the highest frequency fl of RS &gt; RW is _Ηζ. Using the same wire of the above-mentioned coil, the coil is wound 8 times into a coil of the same shape [Μ = .^H, Ls is approximately the center H, the approximate calculated lightness coefficient η, ,, spoon is 0, 8 3 〇 wire As described above, the coil obtained by winding 8 times as described in Japanese Laid-Open Patent Publication No. Hei No. 8-148360 is actually the same as the equivalent series 319286 67 1331432. In addition, the frequency characteristics of RW are also poor, and it is ensured. The fully reactive • rfj frequency region does not satisfy RS &gt; Rw. Therefore, although the 'inappropriate method and the winding method are not selected, the minimum inductance and coupling coefficient used in the high-frequency* rate region can be ensured. Therefore, the minimum of the above-mentioned measured results is specified at least 8 times. The number of windings is specified as the lowest value of the inductance.

When it is 8 times, the outer diameter becomes 3 times χ 2 times χΐ. 5mm + 30mm = 39mm. Therefore, in the coil constituted by the wire described in Japanese Laid-Open Patent Publication No. Hei 08-148360, the coil outer diameter D and the line k d3 # are 39/1.5 in order to ensure the lowest value of the inductance 2/z H and the coupling coefficient. = 26' coil outer diameter d must be at least 25 times the wire diameter d3. However, as mentioned above, the characteristic structure of "D must be at least 25 times that of d3" may change the minimum value of inductance by 2/z due to changes in other components such as wire or number of turns. H and the transfer coefficient. For example, consider a case where the diameter of the wire is made thinner, and a space is provided between the wires. Therefore, in order to ensure the minimum value of the inductance 2 # Η, it is necessary to have more than 8 windings. In order to ensure the lowest value of the inductance, the number of windings of the wire is used, and finally, the frequency characteristic of ==n, Rs in the coil formed by the single (4). The so-called "unified" === coil_, is self-evident. Therefore, it is prescribed that a is the operating condition of the aforementioned coil derived from the characteristics obtained by the actual measurement of the coil 319286 68 1331432. * Repeatedly, the coil system only specifies, for example, a specific configuration, and t-he constitutes a factor change, thereby having an infinite configuration substantially. Compared with the second invention, the invention whose specific constitution is defined as the gist does not prove that the specific configuration is specified, and the circle achieves the effect of constantly exhibiting excellent power transmission performance. In addition, it is virtually impossible to prove. Only by the present invention, the lowest value of the above-mentioned inductance is 2# Η and

As indicated above, the present invention is not the same as the prior art, and is a material showing the measured characteristics in various embodiments. A coil system having a structure that can be inductively coupled has an indefinite change. Therefore, it is impossible to ensure power transmission in the coil of any configuration. Further, in the prior art, it is not even possible to judge a coil which is specifically constituted by a single meaning to ensure power transmission performance. The coil selected by the above method can realize the performance of the coil of the power-supplying device of various configurations (four) power transmitting device only by specifying the operating conditions generated by the characteristics specified by the purpose of the invention. This superior effect is not achieved in the conventional technique of specifying only a specific configuration of the coil. In addition, one coil satisfies the highest frequency of RS &gt; Rw, and is preferably 500 kHz or more. The same coil is used to ensure that the frequency of the reactance uses a coil that satisfies the highest frequency fl of Rs &gt; Rw. For example, driving at less than 250 kHz can be confirmed to ensure power transmission performance. Alternatively, one coil satisfies the highest frequency f2 of Rs &gt; RngRw is 5 〇 this edge is 319286 69 1331432. The above is more preferable.

In the frequency region of 隹φ<6〇, the power factor is %%, the frequency with the highest force factor is lower, and the higher the factor, the higher the frequency. It can be seen from Fig. 34 and Fig. 35 that when the load resistance value is low, electricity is obtained. When the load resistance value is high, power. In addition, when the load resistance value is low, the maximum value of the power factor is large. When the load resistance value is high, the maximum value of the power factor will be small. If it is 5 Ω or less of the minimum load resistance value generally used, the frequency with the highest power factor is less than the 线圈 of one coil. In Fig. 34, when two air-core coils are used, the load resistance value that satisfies the power factor of 50% or more is less than or equal to 1 Ω in the maximum frequency fl = 67 kHz of Rs &gt; Rw. In Fig. 35, when the air core coil 1A is used in the power transmission coil and the air core coil if is used in the power receiving coil, the power factor of 5 〇% or more is satisfied in the maximum frequency fl = 11 kHz which satisfies Rs &gt; rw The load resistance value corresponds to 50 Ω. Further, comparing Fig. 34 and Fig. 35, in Fig. 35, as the enthalpy rises, the maximum value of the power factor also rises. 70 319286 1331432, even if the relationship between power transmission efficiency and frequency in Fig. 9 and Fig. 13 is observed, it can be known that fl will rise and power transmission performance will increase. In particular, when the two frequencies are above Π, the power transmission efficiency π is extremely deteriorated. In the power transmission device of the conventional configuration of the coil of the prior art, such as the Japanese Patent Laid-Open No. Hei 8-148360, Only the embodiments that earned at a specific frequency are described. The frequency already stated is not limited to lGGkHz. However, as described above, the power factor and the equivalent series resistance Rw of the coil vary depending on the frequency. If the frequency is not set at the maximum point of the power factor in the minimum value Rm of the load resistor RL, the power caused by the equivalent series resistance Rw is lost due to the invalid power. As described above, the frequency characteristics of Rw, Rs, and Rn are measured to obtain 〇 and f2. The frequency at which the power factor is the highest is preferably less than ^. In autumn, when the load resistance value RL becomes larger, the ratio of the equivalent series resistance of the coil to the front: = Rw/RL becomes smaller. Therefore, due to the power loss caused by the load, the load power is relatively small. Therefore, even in the case where the load resistance value is large, the power factor becomes small, but power transmission can be performed at an unsuccessful frequency. The effective power transmission efficiency &quot; frequency characteristics of Fig. 9 and Fig. 13 will be described below. Connect the Η)Ω non-inductive load resistor to the power receiving coil and measure the impedance on the power transmitting side. The phase angle is obtained on the power transmitting side by measuring the impedance: and the power factor c 〇 W at each frequency is calculated.

The effective power Pr of the power generation side is formed by the pr=c〇s furnace and is long. The effective power Ps on the secondary side is obtained by taking the non-inductive load resistance of 1 Ω. The effective value Ve of the voltage across the two ends is obtained by forming Ps=Ve2/1〇. The effective power transmission efficiency of each frequency is determined by forming π = Ps/Pr. This measurement method is different from the Japanese Patent Laid-Open No. Hei 4-122007, which does not take into consideration the change in the power factor due to the load resistance value or the frequency. X Try to obtain the load resistance value from the power that must have the actual electrical machine. The electric power of the electric machine must be equal to the voltage Vs=5V, the current Is?=0.5A, and the electric power of about 2.5W. Therefore, the minimum value of the load resistance value is about 10Ω. In an electric machine that must have a power of 1 〇w or more, the voltage Vs is increased and the current Is is decreased. Even if the actual circuit power is about 5V, most of them use a buck-type ρ·(10)% widthmodulaton’·pulse width modulation converter. For example, a personal computer such as a computer that has a power of about 30 W is used as a power source for i5v and 2a. The minimum value of the load resistance value RL at this time is 15/2 = 7 5 〇 left # right. When the voltage Vs is further increased and the current Is is decreased to be about 3 〇 v and 1 A, the minimum value of the load resistance value RL is about 3 〇 / 1 = 3 〇 Ω. In terms of the approximate target, the minimum value of the load resistance RL is about 2 〇 to 5 〇 Ω. Therefore, in order to suppress the power loss due to the equivalent series resistance of the coil to about 20% or less of the received power, if the minimum value of the load resistor RL is Rm, the equivalent series resistance Rw of the power receiving coil must satisfy Rwx5 S Rm. That is, in the output frequency fa of the AC power source, the Rw of the power receiving coil is preferably 0.4 Q to 1 〇 Ω or less. According to the actual measurement, the resistance component on the power transmission coil side is implemented in the above-mentioned embodiment 72 319286 1331432. Although the frequency varies depending on the frequency, it is equal to or less than the load resistance value RL. Therefore, when the minimum value of the load resistor RL is Rm, the equivalent series resistance RW of the power transmitting coil and the power receiving coil is preferably 〇 4 Ω to 1 〇 Ω or less. When the upper limit of the equivalent series resistance RW is determined, Rs and Rn are actually measured and found. In fl, the equivalent series resistance is preferably 〇 4 Q to 1 〇 Ω or less. Therefore, in the frequency at which the coil is actually used, Rs and Rn are preferably 10 Ω or less. As shown in Fig. 2, in the above, the power transmission causes the loss of the eddy current loss caused by the magnetic flux generated by the current flowing to the power transmitting coil and the power receiving coil to pass through the other coil. The loss increased. As described above, when power transmission is actually performed, the values of R1 and R2 in Fig. 8 are not known. Therefore, the above-described actual equivalent series resistance Rw is the same as that of the intestine $(Tw-Ta) / (Ia2x0i) depending on the conditions of use of the power receiver. Among them, the magnetic material plate or the metal plate is sometimes brought close to the air core coil for the purpose of shielding the magnetic flux. In the case as described above, the proximity of the general magnetic material plate or the metal plate deteriorates the power transmission performance of the air core coil. For example, a case where a magnetic material plate or a metal plate is provided on the opposite side of the opposite surface of the coil of the slab 21, the embodiment of the 22A, or the wire of the 28a is wound into a spiral of a flat core single-layer spiral. Wait. Alternatively, in the embodiment of Fig. 27a, a magnetic material having a low magnetic permeability is provided in a bobbin-shaped inner diameter cavity, or a cylindrical metal ring is provided in a cavity. Further, in the embodiment of Fig. 22A, a metal plate having a width equal to or less than one-fifth of the outer diameter of the coil is formed into two crosses, and 319286 73 1331432 is affixed to the insulating material. Even in the case as described above, it is also a right-handed hall that satisfies the obstacle shape of Rhe&gt;Rw or Rs&gt;RgRw in a certain frequency range, but is plugged into a 'magnetic material, a metal plate If the performance of the air core coil body of the present invention is not the same, the coil is substantially regarded as an air core. '·' &quot; The air core coil of the embodiment of the present invention has a high magnetic field strength generated by the coil. Because &amp; ^ single H, therefore, for example, as shown in the paragraph number 〇〇〇8 of the Japanese Patent Laid-Open No. 00-263, in order to shield the electronic components of the machine by the magnetic field, when facing the opposite side of the coil When the opposite side is provided with a magnetic material, a metal plate, or the like, the opposite side of i1, the purpose is not to improve the power transmission performance of the air-core coil, but only to be provided as a magnetic shielding material. The case as described above is not an invention made up of one configuration, but is based on the invention, and is intended for other effects. That is, the improvement of the characteristics or performance of the air-core coil of the non-inventive embodiment is aimed at, and the power transmission performance of the empty 4-core coil in the embodiment of the present invention when the magnetic material or the metal material is close to the embodiment of the present invention is not itself empty. The coils are considered to be hollow cores and are included in the scope of the present invention. For example, even if the inductance is increased, if the equivalent series resistance Rw is increased and the performance is not improved, the above-described embodiment of the present invention can be used for the coil characteristics. The deterioration occurs, that is, it cannot be improved. In the embodiment of the present invention, the conductors forming the conductors of the wires are not limited to each other. However, in the hollow core coils described in the present embodiment, steel is used for the conductors. In the case of a conductor, it is preferable to use copper having a smaller specific resistance, but other metals or alloys having a smaller specific resistance can also be used as a guide 74 319286 1331432

此外，在進行上述說明之各空芯線圈的等效串聯電阻 或電感的測量時，至1MHz為止係使用安捷倫（Agilen〇 公司的LCR測試儀4284A，測量1MHz至10MHz時，係 使用惠普（Hewlett-Packard )公司的LCR測試儀4275A。 其中，1MHz至10MHz的量測係僅可在i、2、4、1〇MHz 的各點進行量測，因此，例如當在4MHz滿足Rs&gt;Rw， 在10MHz不滿足rs&gt;Rw時，藉由插值（imerp〇iati〇n)， 來推定滿足Rs &gt; Rw的最高頻率fi。 如上所示，根據本發明之實施形態，將一方線圈單體 的等效串聯電阻設^ Rw。冑當與一方、線圈相對向的另一 方線圈短路時之-方線圈㈣效串聯電阻設為&amp;。將滿足In addition, when performing the measurement of the equivalent series resistance or inductance of each of the air-core coils described above, Agilent (Agilen® LCR Tester 4284A) is used up to 1 MHz, and HP is used when measuring 1 MHz to 10 MHz (Hewlett- Packard) LCR Tester 4275A. Among them, the 1MHz to 10MHz measurement system can only measure at various points of i, 2, 4, 1〇MHz, so for example, when Rs>Rw is satisfied at 4MHz, at 10MHz When rs&gt;Rw is not satisfied, the highest frequency fi satisfying Rs &gt; Rw is estimated by interpolation (imerp〇iati〇n). As shown above, according to an embodiment of the present invention, the equivalent series of one coil unit is connected in series. The resistance is set to Rw. When the other coil that is opposite to the coil and the coil is short-circuited, the square coil (four) effect series resistance is set to &amp;

By using a coil with a higher fl, the output frequency fa of the AC power source is set to a frequency less than fl, whereby the power transmission performance can be improved more than the prior art. Next, when the other coil facing the one coil is opened, the equivalent series resistance of the square coil is set to Rn(Q), and observation is made.

When connecting the load resistor, the secondary side coil is connected! The ratio of the reactance X to the pure resistance R of the secondary side coil to the opposite side of the secondary side coil is such that the phase difference between the AC voltage and the alternating current of the coil becomes extremely small ° = (4) becomes extremely large, and the equivalent series resistance is compared Small frequency, use coil, hunting this can get the accumulation rate (- "Μ.. Good with 319286 75 1331432 'high power transmission performance, power transmission device can also be used at high frequency. How to coil. Results ' Since the I-effect power and the apparent power during power transmission can be reduced, the power loss due to the equivalent series resistance of the coil can be reduced. Furthermore, the equivalent series resistance Rw(d) of one coil unit can be specified. The thermal condition of the current Ia(A) flowing to the square coil can specify the upper limit of the current value la of one coil, or the upper limit of the number of turns of the equivalent series resistance of one coil, or the equivalent series resistance Rw. In the frequency region, when using a collection of bare single conductors of 0.3 mm or less, the hunting improves the power transmission performance by suppressing the increase in the equivalent series resistance of the coil due to the skin effect and the thirst flow loss. Structure An insulator is disposed inside the wire of the coil, and by reducing the volume of the conductor passing through the magnetic flux passing through the wire, the increase of the equivalent series resistance due to the skin effect and the eddy current loss can be suppressed. Moreover, the wire can be made flexible, and the wire can be bent. For example, by measuring the frequency characteristic of the human Rn, the frequency range of the second power transmission can be specified or even if the actual upload is tested. It can also predict the performance of power transmission. By using the coil shown above, it is possible to transmit large power at a high frequency. . . . 'When using an air core coil without magnetic material, the coefficient is about 0.9 to *7 The human I7 enables the coupled state and the coupled state to ensure that the power is detailed.
