Because the reason that the technical staff understands easily, hub portion 5 preferably makes of the soft magnetic material with low magnetic resistance.Yet for the reason of making and assembling, top hub portion 5 can do with steel especially.
In addition, also comprise ten bipolar magnets that are designated by numeral 6 with logical at this routine rotor 2, each magnet be shaped as six cuboids, each magnet is fixed on the side in the side of hub portion 5.
These those skilled in the art understand easily, and its magnetic resistance of device that is used for magnet 6 is fixed in the hub portion 5 must be low as much as possible, and this device can have various characteristics and not shown on figure.
The magnetization axis of the magnet 6 that the arrow that is used for numbering in Fig. 1 is represented is all in radial direction, but has the direction of magnetization alternately.Magnet 6 on the periphery of rotor 2 is an even number, is 10 in this example, has south poles alternately.Therefore magnet 6 produces 10 radial magnetic fields that direction replaces in the outside of rotor 2.Have north magnetic pole or have south magnetic pole on the periphery of rotor 2 according to magnet 6, magnet 6 illustrates with compiling 6a or 6b respectively hereinafter.
The stator 3 of generator 1 comprises first and second stator plate, and they represent that with numbering 7 and 8 general shape of the two is smooth annular respectively, and its center is on pivot center A and perpendicular to this axis A.These stator plate 7 and 8 are spaced from each other, and wherein each plate is arranged in a near surface of hub portion 5 end surfaces at least approx, and these plates are all made of soft magnetic material.
In this example, stator 3 also comprises five profile of tooth bodies of first group, and these profile of tooth parts all are designated by numeral 9, and makes of soft magnetic material, and is arranged on equably around rotor 2 and makes in the space that rotor and stator plate 7,8 separate.This profile of tooth part 9 on angle, be separated by 360 °/N angle and be parallel to the pivot center A of rotor 2, these profile of tooth parts mechanically with on the magnetic are connected in stator plate 1 and extend along the direction of stator plate 8.
In addition, stator 3 also comprises five profile of tooth parts of second group, and these profile of tooth parts all are designated by numeral 10, and also make of soft magnetic material, also be arranged on equably around rotor 2 and make in the space that rotor and stator plate 7,8 separate, each profile of tooth part 10 is also between two profile of tooth parts 9.Therefore profile of tooth part 10 angle of 360 °/N of on angle, being separated by.In addition, they also are parallel to the pivot center 4 of rotor 2, and mechanically with on the magnetic are connected in stator plate 8, and extend along the direction of stator plate 7.
As can be seen, the sum of the profile of tooth part 9,10 of stator 3 equals the magnet 6a of rotor 2 and the sum of 6b, and when the latter occupied as shown in Figure 1 position, then each profile of tooth part 9 and 10 was positioned at towards the position of one of them magnet 6a and 6b.
Very clear, the various parts of above-mentioned generator 1 should be chosen its size and configuration like this, promptly make rotor 2 freely to rotate and do not touch any parts of stator 3, and the distance that makes magnet 6a and 6b and profile of tooth part 9 and 10 separate should make mutual inductance solenoid magnetic flux and magnetic resistance coupling all have favorable values.
Those skilled in the art find out easily, preferably for example adopt the suitable plate of material of cutting or bending and make the same single parts by stator plate 7, profile of tooth part 9 and arm 11 and by two unit that stator plate 8, profile of tooth part 10 and arm 12 constitute respectively.
In addition, those skilled in the art will find out that also these two parts can be identical, have so just simplified the manufacturing of generator, have reduced manufacturing cost.
The core bar 14 of coil 13 is also made of the soft magnetic material of low magnetic resistance certainly, and unshowned assurance also is arranged to have alap magnetic resistance with the device that core bar is connected in arm 11 and 12.
The mechanical connection that the core bar 14 of coil 13 guarantees between two said units.But generally need strengthen this mechanical connection on these unit, thereby guarantee that these unit all keep correct position mutually in all cases by one or more support bars are fixed on.Because the reason that those skilled in the art understand easily, these unshowned support bars must be made of nonmagnetic substance.
Those skilled in the art also can see, according to the relative size of generator 1 various parts, at each end 14a of core bar 14 and 14b other support bar of also essential configuration respectively and between the arm 11,12, this cramp bar is also made of the soft magnetic material of low magnetic resistance certainly.
Those skilled in the art also can see, in the situation of other embodiment of the generator of the present invention of explanation subsequently, the consideration of required work be similar to the connection support bar of said units is done and/or the end with core coil is connected in the consideration that the support bar of respective wall is done.Therefore below this is no longer repeated.
Should also be noted that, just the various parts of the stator 3 of explanation so are formed, determine size and are provided with mutually, make the unit that constitutes by stator plate 7, profile of tooth part 9 and arm 11 and the unit that constitutes by stator plate 8, profile of tooth part 10 and arm 12 on magnetic only the core bar 14 by coil 13 be connected.
Can find out easily, because the structure and the configuration of above-mentioned generator 1 various parts, when rotor 2 rotated with respect to stator 3, the variation that coil 13 originates from response the magnetic flux of magnet 6a and 6b produced voltage, and this magnetic flux alternately passes core bar 14 along a direction and another direction.
The coil 13 of generator 1 is on core bar, and on core bar 14, this goes far towards its manufacturing and processing in this example.
In addition, when all other conditions were identical, the winding average length of the coil 13 of generator 1 and the total length wiry that forms above-mentioned coil 13 were respectively less than the average length of the coil windings of this known motor and the total length wiry that constitutes above-mentioned back one coil.
Since these two facts, the cost of the coil 13 of generator 1, thereby the cost of generator 1 will be lower than the cost of known generators coil and the cost of generator respectively.
In addition, still under the identical situation of all other conditions, the resistance of the coil 13 of generator 1 is lower than the resistance of known generators coil, because the total length of metal wire that constitutes above-mentioned coil 13 is less than the metal wire total length that constitutes the known generators coil.
Can draw thus, the loss of the Joule effect that produces in coil 13 is less than the loss under the known generators situation.Therefore the energy output of generator 1 is higher than the energy output of known generators.Can also draw, no matter providing electric current does not still provide electric current, the change in voltage that generator 1 is produced is lower than the change in voltage under the known generators situation.
Those skilled in the art are easy to see that the rotor 2 of generator 1 can comprise that number is different from 10 permanent magnet 6a and 6b, however this number even number and always equal the total number of contained profile of tooth part in the stator 3 always.
Equally, regardless of its number, magnet 6a and 6b can replace with a single multipole permanent magnet, this multipole permanent magnet is so arranged certainly, promptly the magnetic pole that is had on the periphery of rotor 2 is the same with the bipolar magnet assembly that is substituted by its, and make by multi-pole magnet in the rotor 2 outside magnetic fields that produce also be radially and on direction, replace.
Generally as can be seen, the rotor that the rotor of generator has for example just illustrated comprises the magnetic device that is made of some bipolar permanent magnets or be made of the multipole permanent magnet of an annular, this magnetic device has 2N magnetic pole, be evenly arranged on the periphery of rotor, and produce the radial magnetic field of direction alternation in the outside of this rotor.Can also say that the stator of this generator comprises two groups of profile of tooth parts, each group has N profile of tooth part, and N profile of tooth part of first group N profile of tooth part and second group is in first and second stator plate that are connected on the magnetic in said stator.
Those skilled in the art can find out that also previous consideration clearly is applicable to other embodiment of the generator of the present invention of explanation subsequently, therefore no longer repeats these considerations.
In the embodiment shown in Fig. 3 and 4, the generator of the present invention that is designated by numeral 21 comprises rotor 2, and the rotor numbering of the numbering of this rotor and generator shown in Fig. 1 and 21 is identical, because it is just the same with the latter, so the rotor 2 of generator 21 is described no longer.
Find out that easily in the generator 21 of Fig. 3 and 4, the magnetic line of force that originates from magnet 6a and 6b is separated into two substantially the same at least parts, a part is passed the core bar 14 of coil 13, and another passes the core bar 26 of coil 25.
It can also be seen that when rotor 2 rotated with respect to stator 22, each coil 13 and 25 produced voltage in response to the variation of the magnetic line of force part of passing its core bar 14 or 16 respectively.
Should be noted that stator plate 7 and two arm 11 are identical with stator plate 8 and two arm 12 and 24 with 23 fully, have so just reduced the manufacturing cost of generator in Fig. 3 and the embodiment shown in 4.
In addition, generator 21 comprises that the advantage of two coils is, total magnetic line of force has only half core bar that passes above-mentioned coil, so just can reduce the cross section of core bar and can not increase the magnetically saturated danger of core bar and/or reduce this magnetically saturated danger.Therefore for the coil number of given number.This embodiment compares with the embodiment of previous Fig. 1 and 2, can reduce the loss of resistance and Joule effect.In addition, because straight coil core bar is convenient to the coiling electric wire,, and can reduce space requirement and its compact structure of maintenance simultaneously to generator so the configuration of present embodiment allows to twine a large amount of coil numbers.The advantage of this embodiment also is applicable to the parallel crooked core bar on core bar of coil.
