Description
本發明係關於用於電動馬達之無心繞組的領域。 This invention relates to the field of centerless windings for electric motors.
包括無心繞組之電動馬達在此項技術中為已知的。無心繞組亦稱為無鐵繞組或空心繞組或自常駐繞組。無心繞組與習知繞組相比之主要優點中之一者為減輕的重量及低惰性,例如用以提供具有快速加速度及響應之轉子。另一優點為歸咎於缺少磁心之低電感,從而減少諸如刷具之電氣干擾及漸增性磨損的缺陷並增加馬達之壽命。 Electric motors including centerless windings are known in the art. Uncentered windings are also known as iron-free windings or hollow windings or self-standing windings. One of the main advantages of a centerless winding compared to conventional windings is reduced weight and low inertness, for example to provide a rotor with fast acceleration and response. Another advantage is due to the lack of low inductance of the core, thereby reducing electrical interference such as brushing and increasing wear and increasing the life of the motor.
已知製作無心繞組之各種技術。一般而言,無心繞組之目標包括:最大功率密度;由繞組之線圈或迴路收集的磁通量之最大值;達成針對給定大小之高扭矩或速度,或類似地,達成針對所需扭矩或速度之較小大小。另一重要問題為簡化導線之製造製程,且尤其簡化導線之繞組製程。另一問題為避免或至少減少導線之間的交叉。導線交叉產生以下缺陷,該等缺陷包括:絕緣故障之較高風險;以及針對減少迴路數量之需要,其中減少迴路數量以便在導線之間留有必要的空間並避免 導線之損壞。然而,減少迴路數量將減小繞組之效能,該效能例如,由包含繞組之轉子輸送的扭矩。 Various techniques for making centerless windings are known. In general, the goals of a centerless winding include: maximum power density; the maximum value of the magnetic flux collected by the coil or loop of the winding; achieving a high torque or speed for a given size, or similarly, achieving the desired torque or speed. Smaller size. Another important issue is to simplify the manufacturing process of the wires and, in particular, to simplify the winding process of the wires. Another problem is to avoid or at least reduce the intersection between the wires. Wire crossing creates the following defects: high risk of insulation failure; and the need to reduce the number of loops, which reduces the number of loops to leave the necessary space between the conductors and avoid Damage to the wire. However, reducing the number of loops will reduce the effectiveness of the winding, such as the torque delivered by the rotor containing the windings.
電動馬達之先前技術無心圓柱形繞組通常具有三角形線圈、六角形線圈或菱形線圈。可在DE 2931725中發現該等已知實施例之概述。在US 3 360 668中揭示最初由Faulhaber博士提出的三角形不含鐵電樞繞組。 Prior art centerless cylindrical windings for electric motors typically have a triangular coil, a hexagonal coil or a diamond coil. An overview of these known embodiments can be found in DE 2931725. A triangular iron-free armature winding originally proposed by Dr. Faulhaber is disclosed in US Pat. No. 3,360,668.
正在對無心自常駐繞組之早期技術進行不斷開發,例如,在EP 2 642 636中揭示一種具有菱形線圈之改良的無心繞組之最近的實例。 A recent development of an unintentional winding of a diamond-shaped coil is disclosed, for example, in EP 2 642 636.
實際上,存在持續的誘因來改良用於電動馬達之無心繞組的效能。詳言之,存在強烈的誘因來尤其在諸如醫療設備、機器人學、航太工業及航空工業的技術領域中提供此類電動馬達,其中該等電動馬達具有無心轉子,該等無心轉子具有小直徑但能夠輸送高扭矩及/或達至相當高的速度。尤其在航空學之領域中,減小重量為另一挑戰。與無心圓柱形繞組、尤其小直徑無心圓柱形繞組有關的技術問題中之一者為,組成繞組之每一單個線圈的導線之佈置。 In fact, there are continuing incentives to improve the performance of the centerless windings for electric motors. In particular, there are strong incentives to provide such electric motors, particularly in the technical fields such as medical equipment, robotics, aerospace industry and aerospace industry, wherein the electric motors have a centerless rotor with small diameters However, it is capable of delivering high torque and/or achieving a relatively high speed. Especially in the field of aeronautics, reducing weight is another challenge. One of the technical problems associated with centerless cylindrical windings, particularly small diameter centerless cylindrical windings, is the arrangement of the wires that make up each individual coil of the winding.
更詳細而言,先前技術多相無心繞組之缺陷為,導線之迴路的不對稱佈局。製作無心繞組之習知製程提供,具每一相之迴路一次一個地順序纏繞,形成圍繞圓柱之若干同心層。此技術之缺點在於,每一迴路必須佈置於先前形成的迴路之上。此舉導致與對稱佈局之 偏差,且與對稱之偏差將導致繞組為電不平衡。可藉助於第20圖及第21圖更好地理解先前技術之此缺陷。 In more detail, the defect of prior art multiphase centerless windings is the asymmetrical layout of the loops of the wires. A conventional process for making a centerless winding is provided, with each phase of the loop being wound one at a time, forming a plurality of concentric layers around the cylinder. The disadvantage of this technique is that each loop must be placed above the previously formed loop. This led to a symmetrical layout Deviations, and deviations from symmetry, will cause the windings to be electrically unbalanced. This drawback of the prior art can be better understood by means of Figs. 20 and 21.
第20圖展示習知三相波形繞組的根據一平面的截面,該平面垂直於其主軸並位於繞組之半高度處。該截面由區域100、101及102組成,該等區域100、101及102各由具單一相之迴路穿過,例如,區域100含有相U之迴路,區域101含有相V之迴路,區域102含有相W之迴路。如圖式所示,區域100、101及102具有不同形狀及尺寸。一個原因在於,例如,首先將相U之迴路圍繞圓柱形表面佈置,從而留下的空間不足夠用於後續相V之迴路,該後續相V之迴路必要地在外層上(亦即,以自軸的更大距離)經過;然後第三相W之迴路容納於剩餘空間中。然而,如上所論述,此技術導致非所要地缺少對稱及電不平衡。 Figure 20 shows a cross-section of a conventional three-phase wave winding according to a plane perpendicular to its major axis and at half the height of the winding. The section is comprised of regions 100, 101, and 102, each of which passes through a loop having a single phase, for example, region 100 contains a phase U loop, region 101 contains a phase V loop, and region 102 contains Phase W circuit. As shown in the figures, regions 100, 101 and 102 have different shapes and sizes. One reason is, for example, that the circuit of phase U is first placed around the cylindrical surface so that the space left is not sufficient for the circuit of the subsequent phase V, which is necessarily on the outer layer (ie, from The larger distance of the shaft passes; then the loop of the third phase W is accommodated in the remaining space. However, as discussed above, this technique results in an undesirable lack of symmetry and electrical imbalance.
第21圖展示習知非對稱疊繞組之截面的典型外觀。 Figure 21 shows a typical appearance of a cross section of a conventional asymmetric stack winding.
先前技術之另一問題為難以在線圈形成期間控制電傳導性導線之位置。導線通常圍繞銷釘纏繞以獲得所要圓柱形繞組。在習知三角形繞組中,在兩個鄰接銷釘之間存在導線之相對長的筆直部分。導線之此部分可偏離兩個銷釘之間的理想直線,由此提出非對稱性之另一來源。 Another problem with the prior art is that it is difficult to control the position of the electrically conductive wires during coil formation. The wires are typically wound around the pins to obtain the desired cylindrical winding. In conventional triangular windings, there is a relatively long straight portion of the wire between two adjacent pins. This portion of the wire can deviate from the ideal line between the two pins, thereby presenting another source of asymmetry.
交叉區域給出另一問題。在多相圓柱形線圈中,具有不同相之線圈在某些區域處交叉,通常在圓筒 高度之約三分之一及三分之二處交叉。在交叉區域中,系統之一個相的例如經向下引導之導線與另一相的例如經向上引導之導線交叉。因此,導線密集交錯並更加暴露於可劣化其絕緣層之機械應力。 The intersection area gives another question. In a multi-phase cylindrical coil, coils with different phases intersect at certain areas, usually in a cylinder About one-third and two-thirds of the height intersect. In the intersection region, for example, a downwardly directed wire of one phase of the system intersects, for example, an upwardly directed wire of another phase. As a result, the wires are densely staggered and more exposed to mechanical stresses that can degrade their insulating layers.
本發明之目的係改良上述先前技術及解決以上問題。 It is an object of the present invention to improve the above prior art and to solve the above problems.
本發明之目的係提供一種用於電動馬達之無心圓柱形繞組的新型佈置,該無心圓柱形繞組具有高功率密度並有能力相對於繞組之大小(直徑)輸送高扭矩或速度。本發明之另一目的係簡化繞組技術,避免尤其繞組之各種線圈的導線之間的交叉(重疊)。本發明之另一目的係減小繞組之非對稱性,從而具有更好的電平衡。 It is an object of the present invention to provide a novel arrangement for a centerless cylindrical winding of an electric motor having a high power density and the ability to deliver high torque or speed relative to the size (diameter) of the winding. Another object of the invention is to simplify the winding technique and avoid crossover (overlap) between the wires of the various coils of the windings in particular. Another object of the invention is to reduce the asymmetry of the windings to provide better electrical balance.
使用根據隨附申請專利範圍之無心繞組來達成此等目的。 These purposes are achieved using a centerless winding according to the scope of the attached patent application.
本發明之第一實施例為具有圓柱形狀之多相無心繞組,該多相無心繞組之特徵為包含具有至少六個側面並以波形繞組纏繞之迴路。 A first embodiment of the invention is a multi-phase, centerless winding having a cylindrical shape characterized by a circuit comprising at least six sides and wound in a wave winding.
在較佳實施例中,繞組包含複數個區段,該複數個區段針對與每一相進行連接而言均包括兩個區段,繞組之針對每一相之兩個區段以180電角度相對,且繞組之連接至兩個不同相的兩個鄰接區段之間的角距離(偏移)為360/(2n)電角度,其中n為相之數量; 例如,在三相繞組中,該等相之間的該偏移為60電角度,且繞組之該兩個區段以180電角度相對。因此,該繞組可稱為60°三相繞組。在具有5個相之繞組中,例如,該偏移為36°(el)。 In a preferred embodiment, the winding comprises a plurality of segments, each of which includes two segments for connection to each phase, the windings having an electrical angle of 180 for each of the two segments of each phase In contrast, and the angular distance (offset) between the two adjacent segments of the winding connected to the two different phases is 360 / (2n) electrical angle, where n is the number of phases; For example, in a three phase winding, the offset between the phases is 60 electrical degrees, and the two sections of the winding are opposite at 180 electrical degrees. Therefore, the winding can be referred to as a 60° three-phase winding. In a winding having 5 phases, for example, the offset is 36° (el).
應將在此描述中針對角度(度)之所有引用理解為電角度,除非另外指出。在旋轉電機中,機械角θm及對應電角度θel遵循方程式θm=θel/np,其中np為磁極對之數量。例如,在具有定子、轉子和兩對極(四個極)的馬達中,轉子相對於定子的一個机械轉動等於兩個電轉動。根據本發明之繞組可具有兩個極或更大數量的極,例如四個極或更多。符號(el)將用於電角度之標誌法,例如60°(el)表示60電角度。 All references to angles (degrees) in this description should be understood as electrical angles unless otherwise indicated. In a rotating electrical machine, the mechanical angle θ m and the corresponding electrical angle θ el follow the equation θ m = θ el /np, where np is the number of magnetic pole pairs. For example, in a motor having a stator, a rotor, and two pairs of poles (four poles), one mechanical rotation of the rotor relative to the stator is equal to two electrical revolutions. The winding according to the invention may have two poles or a greater number of poles, for example four poles or more. The symbol (el) will be used for the signing method of the electrical angle, for example 60° (el) means 60 electrical angle.
每一區段由具有傳導性材料的導線之若干迴路(亦稱為匝)構成,該等若干迴路可能集合成線圈。線圈被理解為導線之基本迴路之群組。例如,繞組之區段(與一個相有關)可包含一或多個線圈,且每一線圈由導線之若干迴路構成。 Each section is made up of several loops (also known as turns) of wires with conductive material, which may be grouped into coils. A coil is understood to be a group of basic circuits of a wire. For example, a section of the winding (related to one phase) may comprise one or more coils, and each coil consists of several loops of the conductor.
每一迴路可視為一些具有不同空間取向之導線區段。該等導線區段簡要稱為迴路之側面或導線。 Each loop can be viewed as a number of wire segments with different spatial orientations. These wire segments are briefly referred to as the sides or wires of the loop.
繞組包括交叉區域,其中迴路之側面連接至彼此交叉的兩個不同相。 The winding includes an intersection region in which the sides of the loop are connected to two different phases that intersect each other.
根據另一較佳特徵,該繞組具有相對於主軸之對稱佈局。根據本發明,該對稱佈局滿足以下條件。 According to another preferred feature, the winding has a symmetrical layout relative to the major axis. According to the invention, the symmetrical layout satisfies the following conditions.
第一,繞組的根據第一平面的截面包含一或多個同心層,其中該第一平面垂直於該主軸並遠離該等交叉區域相交於軸,該一或多個同心層由截面區域相對於該主軸之對稱分佈形成,該等截面區域含有具不同相之迴路,該等截面區域中之每一者含有具僅一個相之迴路。 First, the cross-section of the winding according to the first plane comprises one or more concentric layers, wherein the first plane is perpendicular to the main axis and intersects the axis away from the intersecting regions, the one or more concentric layers being opposed to each other by the cross-sectional area A symmetric distribution of the major axes is formed, the cross-sectional regions containing loops having different phases, each of the cross-sectional regions containing a loop having only one phase.
第二,繞組的根據第二平面之截面包含一或多個同心層,其中該第二平面垂直於該主軸並在交叉區域中相交於軸,該一或多個同心層由相連的交叉區域性區域形成,每一區域含有具兩個相之迴路的均勻分佈。 Second, the cross-section of the winding according to the second plane comprises one or more concentric layers, wherein the second plane is perpendicular to the main axis and intersects the axis in the intersecting region, the one or more concentric layers being connected by a cross-region Zones are formed, each zone containing a uniform distribution of loops with two phases.
作為以上第一條件之結果,相對於繞組之軸,不同相在繞組之截面中呈現對稱分佈,並以360°/n成角度地間隔。例如,三相繞組之截面將展示以120°間隔的大體相同的三個區域,其中每一相用一個區域。亦在交叉區域中,該等相之迴路根據以上第二條件均勻分佈。 As a result of the above first condition, the different phases exhibit a symmetrical distribution in the cross section of the winding with respect to the axis of the winding, and are angularly spaced by 360°/n. For example, the cross-section of a three-phase winding will show three substantially identical regions spaced at 120° with one region for each phase. Also in the intersection region, the circuits of the phases are evenly distributed according to the second condition above.
較佳地,所有相同時地而非順序地纏繞,以形成該對稱無心繞組。此與先前技術形成對比,在先前技術中,具不同相之線圈順序地纏繞從而導致上述缺點。 Preferably, all of the same time, but not sequentially, are wound to form the symmetrical centerless winding. This is in contrast to the prior art in which coils of different phases are sequentially wound to cause the above disadvantages.
申請人已發現波形繞組與具有至少六個側面的迴路之組合就導線之正確定位及減小的非對稱性而言具有特定優點。此組合到目前為止未經提出。 Applicants have discovered that the combination of a wave winding and a circuit having at least six sides has particular advantages in terms of proper positioning of the wire and reduced asymmetry. This combination has not been proposed so far.
導線之具有至少六個側面的迴路具有以下優點:在製造製程期間較好的對導線之位置之控制,因為 導線圍繞位於較短距離處之銷釘纏繞。由此,導線之筆直部分的長度減小,該長度為與迴路之理論形狀之偏差的來源。 A circuit having at least six sides of the wire has the advantage of better control of the position of the wire during the manufacturing process because The wires are wrapped around the pins at a short distance. Thereby, the length of the straight portion of the wire is reduced, which is the source of the deviation from the theoretical shape of the loop.
具有六個側面且較佳為六角形的迴路亦具有以下優點:該等迴路具有比習知(例如菱形)迴路大的表面。因此,每一迴路收集更大量的磁通量。這意味著,在根據本發明之轉子中,例如,每一迴路將輸送更多扭矩。由此,六角形迴路及波形繞組之組合在需要高扭矩時為尤其適合的。 A circuit having six sides and preferably a hexagon also has the advantage that the circuits have a larger surface than conventional (e.g., diamond) circuits. Therefore, each loop collects a larger amount of magnetic flux. This means that in the rotor according to the invention, for example, each circuit will deliver more torque. Thus, the combination of a hexagonal loop and a wave winding is particularly suitable when high torque is required.
根據較佳特徵,為每一相提供繞組之兩個相對區段(用於三相系統之60°繞組)具有以下優點:繞組區段之中心線與磁極之間具有小角度。由此,導線之單一迴路的相對於磁場之佈置更加有效,且對於給定電流而言產生更大扭矩。 According to a preferred feature, providing two opposite sections of the winding for each phase (60° winding for a three-phase system) has the advantage that the centerline of the winding section has a small angle to the pole. Thereby, the arrangement of the single loop of the wire relative to the magnetic field is more efficient and produces more torque for a given current.
上述對稱佈局具有以下額外優點:系統之相的較好的電平衡,因為所有相圍繞繞組之軸均勻分佈。由此,電動勢(electromotive force)之相關分佈亦為對稱的。對稱佈局之一優點係歸咎於低損耗,低損耗在高速應用中具有特別重要性。由此,對稱佈局較佳地尤其用於高速馬達之定子及/或轉子之應用。 The above symmetrical layout has the additional advantage of a better electrical balance of the phases of the system since all phases are evenly distributed around the axis of the winding. Thus, the correlation distribution of the electromotive force is also symmetrical. One of the advantages of a symmetrical layout is due to low losses, which are of particular importance in high speed applications. Thus, the symmetrical layout is preferably used especially for the application of the stator and/or rotor of a high speed motor.
在較佳實施例中,迴路包含兩個軸向延伸的有效側面,該等有效側面可平行於或近乎平行於繞組之軸,或傾斜合適角度。該等軸向延伸的有效側面延伸穿過圓柱形繞組之中央帶或區域。該等有效側面稱為有效 導線,因為大多數情況下,該等有效側面收集更大量的磁通量(可利用通量之50%或更多)並產生輸出扭矩中之大部分。此外,根據該等軸向延伸的側面,迴路包含一些較短的連接腿部,例如,六角形迴路將包含兩個有效側面及兩對上連接腿部及下連接腿部。 In a preferred embodiment, the circuit includes two axially extending effective sides that may be parallel or nearly parallel to the axis of the winding, or inclined at an appropriate angle. The axially extending effective sides extend through a central band or region of the cylindrical winding. These effective sides are called valid Wires, because in most cases, these effective sides collect a larger amount of magnetic flux (50% or more of the available flux) and produce most of the output torque. Moreover, depending on the axially extending sides, the circuit includes some shorter connecting legs. For example, the hexagonal circuit will include two active sides and two pairs of upper connecting legs and lower connecting legs.
迴路之較佳形狀為六角形。本發明之態樣為六角形迴路與對稱繞組之組合,該對稱繞組具有用於具每一相之相對區段,如上文所定義的。申請人已發現相較於先前技術佈置,該等特徵組合減少磁通量之損耗並輸送更大扭矩或更高速度以用於繞組之給定大小(直徑)。 The preferred shape of the loop is hexagonal. Aspects of the invention are a combination of a hexagonal loop and a symmetrical winding having opposing sections for each phase, as defined above. Applicants have discovered that these feature combinations reduce the loss of magnetic flux and deliver greater torque or higher speed for a given size (diameter) of the winding compared to prior art arrangements.
在其中迴路之有效側面佈置為平行於或近於平行於軸的實施例中,有效側面之相對於繞組之軸的傾斜角度較佳為小角度,更佳地,該角度不大於10°(機械角度)。 In embodiments in which the effective side of the loop is arranged parallel or nearly parallel to the shaft, the angle of inclination of the active side relative to the axis of the winding is preferably a small angle, more preferably the angle is no more than 10° (mechanical angle).
其中具有軸向或近乎軸向取向的有效導線之實施例可較佳用於最大化由每一迴路收集的磁通量。有效側面之傾斜減小由每一迴路收集的磁通量之量,而另一方面,為更多迴路之容納留出空間。由此,儘管與理論最佳實施例之偏差,但該傾斜可提供就效能而言之總體益處,例如,就由轉子vs.在迴路中流動的電流之強度輸送的扭矩而言。此外,迴路之有效側面的傾斜使製造製程變得更容易。 Embodiments in which an effective wire having an axial or near axial orientation may be preferred for maximizing the magnetic flux collected by each circuit. The slope of the effective side reduces the amount of magnetic flux collected by each loop and, on the other hand, leaves room for more loop accommodation. Thus, despite the deviation from the theoretically preferred embodiment, the tilt can provide an overall benefit in terms of performance, for example, in terms of the torque delivered by the strength of the current flowing through the rotor vs. in the loop. In addition, the tilting of the effective side of the loop makes the manufacturing process easier.
本發明之另一實施例為根據隨附請求項11之繞組。在此其他實施例中,繞組包含具有至少六個側面的迴路,該等迴路較佳具有六角形形狀,且該等迴路具有每一相用兩個區段(用於三相系統之60°繞組)以及對稱佈局之上述特徵。 Another embodiment of the invention is a winding according to the accompanying claim 11. In this other embodiment, the winding comprises a loop having at least six sides, preferably having a hexagonal shape, and the loops having two sections for each phase (60° winding for a three-phase system) And the above features of the symmetric layout.
迴路之軸向或傾斜的有效側面之以上較佳特徵亦為合適的。 The above preferred features of the axial or inclined effective side of the circuit are also suitable.
在此實施例中,迴路可以波形繞組或疊繞組纏繞。疊繞組亦稱為鏈形繞組(imbricated winding)。疊繞組及波形繞組為熟習該項技術者已知並描述於文獻中。 In this embodiment, the loop can be wound with a wave winding or a stacked winding. Stack windings are also referred to as braided windings. Stack windings and wave windings are known to those skilled in the art and are described in the literature.
在較佳實施例中,匝以疊繞組纏繞並具有小於180電角度之減小的間距(亦稱為開口寬度)。該間距為已知特徵並可定義為迴路之軸向側面之間、或由若干迴路構成之線圈的正中迴路之間的角距離(按電角度量測)。 In a preferred embodiment, the turns are wound in a stacked winding and have a reduced pitch (also referred to as the opening width) of less than 180 electrical degrees. The spacing is a known feature and can be defined as the angular distance (measured by electrical angle) between the axial sides of the loop or between the positive loops of the coils formed by several loops.
減小鏈形線圈之間距就製造製程而言給予重要優點,因為從而減少單一迴路之交叉及重疊。由此,製造方法更容易且導線之損壞的風險減小。短間距亦導致由每一迴路收集的磁通量之損耗;然而,此缺陷由以上積極效果過補償。 Reducing the spacing between the chain coils provides an important advantage in the manufacturing process because it reduces the intersection and overlap of the single loop. Thereby, the manufacturing method is easier and the risk of damage to the wires is reduced. Short spacing also results in loss of magnetic flux collected by each loop; however, this defect is overcompensated by the above positive effects.
更佳地,鏈形迴路之間距包含在360/(2.n)與360/n之間,其中相之數量n為2或更大。甚至更佳 地,在三相實施例(n=3)中,該間距為約100°(el),例如介於90°(el)與110°(el)之間。 More preferably, the chain loop spacing is comprised between 360/(2.n) and 360/n, wherein the number n of phases is 2 or greater. Even better In the three-phase embodiment (n=3), the pitch is about 100° (el), for example between 90° (el) and 110° (el).
在本發明之所有實施例中,三相可連接成星形(Y形)或三角形樣式。此外,在所有實施例中,迴路可具有大於六個側面,例如八個側面。 In all embodiments of the invention, the three phases may be connected in a star (Y-shaped) or triangular pattern. Moreover, in all embodiments, the loop can have more than six sides, such as eight sides.
本發明之繞組可用於電動馬達之轉子及定子兩者中。較佳使用係關於無刷馬達之定子的製造。 The winding of the present invention can be used in both the rotor and the stator of an electric motor. It is preferred to use a stator for a brushless motor.
本發明之特徵及優點將藉助於圖式闡明,該等圖式係關於較佳實施例及非限制性實施例。 The features and advantages of the present invention are set forth by way of the description of the preferred embodiments.

第20、21圖係關於先前技術。 Figures 20 and 21 relate to prior art.
圖式展示本發明之各種實施例。在圖式中,字母U、V、W表示三相系統之相;字母A至F表示繞組之連接的端子。 The drawings show various embodiments of the invention. In the drawings, the letters U, V, W represent the phases of the three-phase system; the letters A to F represent the terminals to which the windings are connected.
在圖式中,坐標系統 x 、 y 、 z 及角坐標 θ el (theta)亦用來描述繞組,如(例如)第1圖所示。該角坐標 θ el 表達電角度。字母 h 表示繞組之按軸向方向 z 量測之高度。如所示,軸 z 可視為圓柱形繞組之主軸。 In the drawings, the coordinate systems x , y , z and angular coordinates θ el (theta) are also used to describe the windings, as shown, for example, in Figure 1. The angular coordinate θ el expresses an electrical angle. The letter h indicates the height of the winding measured in the axial direction z . As shown, the axis z can be viewed as the major axis of the cylindrical winding.
第1圖展示根據本發明之第一實施例的二極三相無心繞組1。 Fig. 1 shows a two-pole three-phase centerless winding 1 according to a first embodiment of the present invention.
繞組1係由導線之六角形迴路組成的波形繞組。更詳細而言,繞組1由六角形迴路2構成。每一六角 形迴路2包含:兩個軸向取向側面3,其在繞組1之中央帶中延伸;以及兩對連接腿部4。 Winding 1 is a wave winding consisting of a hexagonal loop of wire. In more detail, the winding 1 is constituted by a hexagonal circuit 2. Every hex The loop 2 comprises: two axially oriented sides 3 which extend in the central strip of the winding 1 and two pairs of connecting legs 4.
側面3之區域亦稱為繞組1之同軸部分,而腿部4之區域可稱為繞組之非同軸部分。 The area of side 3 is also referred to as the coaxial portion of winding 1, and the area of leg 4 may be referred to as the non-coaxial portion of the winding.
字母A1、A2、B1、B2至F2表示繞組之端子。第18及19圖給出星形連接及三角形連接之實例。第18圖之符號N表示中和點。 The letters A 1 , A 2 , B 1 , B 2 to F 2 represent the terminals of the windings. Figures 18 and 19 show examples of star connections and delta connections. The symbol N in Fig. 18 indicates the neutralization point.
因為繞組1具有兩個極,所以在此情況下,機械角度及電角度相吻合(coincide)。在以下描述中,無論如何,對度數之引用應意指電角度,除非另作說明。 Since the winding 1 has two poles, in this case, the mechanical angle and the electrical angle coincide. In the following description, in any case, reference to degrees shall mean an electrical angle unless otherwise stated.
繞組1可針對每一相均包含一個區段或兩個區段。在第一種情況中,每一區段延伸超過120°(el),且繞組可稱為120°三相繞組。在第二種情況中,具每一相之兩個區段呈180°(el)相對,並延伸超過60°(el);由此,繞組可稱為60°三相繞組。120°或60°之該延伸對應於具兩個相之間的角距離(偏移)。更一般而言,在具有n個相的多相繞組中,該延伸或距離分別為360/n或360/(2n)。 Winding 1 may comprise one segment or two segments for each phase. In the first case, each segment extends over 120° (el) and the windings can be referred to as 120° three-phase windings. In the second case, the two sections with each phase are 180[deg.] (el) opposite and extend over 60[deg.] (el); thus, the windings can be referred to as 60[deg.] three-phase windings. This extension of 120° or 60° corresponds to an angular distance (offset) between the two phases. More generally, in a multi-phase winding having n phases, the extension or distance is 360/n or 360/(2n), respectively.
在60°實施例中,三相繞組1需要十二個連接,亦即,每一區段用兩個連接,且因此每一相用四個連接。該兩個區段具有相反的繞組方向。 In the 60° embodiment, the three-phase winding 1 requires twelve connections, i.e., two connections per segment, and thus four connections per phase. The two sections have opposite winding directions.
第2圖展示在根據坐標 θ el (弧度)及 z 的平面圖中的波形繞組1。在第2圖中,六角形迴路2之側面3 平行於或大體平行於軸 z ,而第3圖例示另一實施例,其中軸向取向側面3相對於軸 z 傾斜角度 β 。 Figure 2 shows the waveform winding 1 in a plan view according to the coordinates θ el (radian) and z . In Fig. 2, the side 3 of the hexagonal circuit 2 is parallel or substantially parallel to the axis z , while Fig. 3 illustrates another embodiment in which the axially oriented side 3 is inclined by an angle β with respect to the axis z .
根據本發明之另一較佳特徵,繞組1具有對稱的佈局。參看第4至6圖可更好地理解此特徵。 According to another preferred feature of the invention, the winding 1 has a symmetrical layout. This feature can be better understood by referring to Figures 4 through 6.
在第4圖中,為了便於用圖形表示,展示迴路中之僅一些者,能夠看出,當例如第一相U與第二相W之兩個相的迴路彼此交叉時,繞組1包含交叉區域5。 In Fig. 4, in order to facilitate the graphical representation, showing only some of the loops, it can be seen that when, for example, the loops of the two phases of the first phase U and the second phase W cross each other, the winding 1 contains the intersection region 5.
對稱的佈局滿足兩個條件,該兩個條件可參考繞組1之根據至少兩個平面P1及P2的截面而定義。第一平面P1垂直於主軸 z 並例如在迴路2之軸向延伸的側面3中遠離交叉區域5與該軸 z 相交。第二平面P2亦垂直於主軸 z ,但是對應於交叉區域5與該軸 z 相交。虛線20為第一平面P1與繞組1之間的交集,且虛線21為與第二平面P2之交集。如第4圖所示,相交線21經過迴路2之交叉區域5。 The symmetrical layout satisfies two conditions, which can be defined with reference to the cross section of the winding 1 according to at least two planes P1 and P2. The first plane P1 is perpendicular to the main axis z and intersects the axis z away from the intersection 5, for example in the axially extending side 3 of the circuit 2. The second plane P2 is also perpendicular to the main axis z , but corresponds to the intersection area 5 intersecting the axis z . The dotted line 20 is the intersection between the first plane P1 and the winding 1, and the broken line 21 is the intersection with the second plane P2. As shown in FIG. 4, the intersection line 21 passes through the intersection area 5 of the loop 2.
較佳地,平面P1位於繞組之半高度處。交叉區域之位置取決於極之數量及相之數量。在二極三相繞組中,交叉區域5位於繞組之高度的約1/3及2/3處。因此,在此種繞組中,上述平面P2較佳地位於高度 h 之1/3或2/3處。 Preferably, plane P1 is located at half the height of the winding. The location of the intersection area depends on the number of poles and the number of phases. In the two-pole three-phase winding, the intersection region 5 is located at about 1/3 and 2/3 of the height of the winding. Therefore, in such a winding, the above plane P2 is preferably located at 1/3 or 2/3 of the height h .
更一般而言,具有N個相及數量np對極之繞組將展示非同軸部分中之若干交叉區域。 More generally, a winding having N phases and a number of np poles will exhibit several intersecting regions in the non-coaxial portion.
在第5及6圖中分別呈現在本發明之對稱實施例中的平面P1及P2之截面。 Cross sections of planes P1 and P2 in the symmetric embodiment of the present invention are presented in Figures 5 and 6, respectively.
在根據平面P1的截面(第5圖)中,可識別總體由數字7表示的六個截面區域。每一區域7含有連接至一個相U或V或W之導線。在實例中,區域7U及7’U含有相U之迴路,且類似地,區域7V、7’V及7W、7’W含有相V及W之迴路。如第5圖所示,該等區域7大體相同,該等區域7相對於該軸 z 對稱分佈且其均勻地間隔。比較而言,此條件未由如第20、21圖所示的先前技術繞組滿足。 In the section according to the plane P1 (Fig. 5), six cross-sectional areas generally indicated by the numeral 7 can be identified. Each zone 7 contains wires that are connected to one phase U or V or W. In the example, regions 7 U and 7' U contain a loop of phase U, and similarly, regions 7 V , 7' V and 7 W , 7' W contain loops of phases V and W. As shown in Fig. 5, the regions 7 are substantially identical, and the regions 7 are symmetrically distributed with respect to the axis z and are evenly spaced. In comparison, this condition is not satisfied by the prior art windings as shown in Figures 20 and 21.
在根據位於交叉區域5中之平面P2的截面(第6圖)中,可識別總體由數字8表示的僅三個區域。更詳細而言,每一區域8UV、8UW或8VW含有均勻分佈的導線,該等導線連接至兩個不同相,亦即U及V或U及W或V及W。 In the section according to the plane P2 located in the intersection area 5 (Fig. 6), only three areas indicated by the numeral 8 in total can be identified. In more detail, each zone 8 UV , 8 UW or 8 VW contains uniformly distributed wires that are connected to two different phases, namely U and V or U and W or V and W.
應將製造之容差納入考慮之中來解釋大體相同區域及對稱分佈之用詞。 The manufacturing tolerances should be taken into account to explain the terms of the same area and symmetric distribution.
應注意,為簡單起見,第5及6圖展示一個層;可提供迴路之若干同心層。 It should be noted that for simplicity, Figures 5 and 6 show a layer; several concentric layers of the loop may be provided.
返回參考第2及3圖,第2圖展示其中側面3平行於軸z之實施例。應注意,即使在「平行的」實施例中,可由製造製程與繞線機(winding machine)之容差導致側面3之輕微(可忽略不計的)傾斜。如第3圖所示,儘管由每一迴路2收集的磁通量中存在損耗,但側面3更顯著的傾斜角度 β 可為較佳的,因為連接腿部4之密 度將增大,且因此將容納更多迴路,且給定電流強度之總輸出扭矩將增大。 Referring back to Figures 2 and 3, Figure 2 shows an embodiment in which the side 3 is parallel to the axis z. It should be noted that even in the "parallel" embodiment, the slight (negligible) tilt of the side 3 can be caused by the tolerance of the manufacturing process and the winding machine. As shown in Fig. 3, although there is a loss in the magnetic flux collected by each circuit 2, a more significant inclination angle β of the side face 3 may be preferable because the density of the connecting leg portion 4 will increase, and thus will accommodate More loops, and the total output torque for a given current level will increase.
角度 β 較佳地不大於10機械角度。 The angle β is preferably no more than 10 mechanical angles.
在本發明之第二實施例中,多相繞組具有:與具有至少六個側面結合的上述對稱佈局;以及繞組之覆蓋360/2n度的區段之上述特徵(三相60°繞組)。 In a second embodiment of the invention, the multi-phase winding has: the above-described symmetrical layout combined with at least six sides; and the above-described features of the winding covering a 360/2n-degree section (three-phase 60° winding).
在此第二實施例中,迴路可具有波形繞組或亦可具有疊繞組。波形繞組及疊繞組為熟習該項技術者所已知。第7圖展示具有波形繞組之迴路2的典型佈置,且第8圖展示具有疊繞組之迴路2的典型佈置。波形迴路通常圍繞繞組之軸( z 軸)轉動,如第7圖所示。 In this second embodiment, the loop may have a wave winding or may also have a stack winding. Waveform windings and stacked windings are known to those skilled in the art. Figure 7 shows a typical arrangement of a loop 2 with wave windings, and Figure 8 shows a typical arrangement of a loop 2 with stacked windings. The waveform loop typically rotates around the axis of the winding ( z- axis) as shown in Figure 7.
參考第9至13圖例示根據本發明之其他實施例的具有六角形迴路的三相鏈形60°繞組10。 Referring to Figures 9 through 13, a three-phase chain 60° winding 10 having a hexagonal loop in accordance with other embodiments of the present invention is illustrated.
第9圖以類似於第4圖之方式例示繞組10,且使用相同數字,第9圖特別展示迴路2中之一些者及該等一些者之交叉區域5。第10圖展示其中迴路之間距減小的較佳實施例之細節。 Figure 9 illustrates the winding 10 in a manner similar to that of Figure 4, and uses the same numbers, and Figure 9 particularly shows some of the loops 2 and the intersections 5 of some of them. Figure 10 shows details of a preferred embodiment in which the distance between the loops is reduced.
繞組10針對每一相U、V、W均包含兩個區段。具每一相之該兩個區段呈180°(el)相對。該等區段中之每一者包含一或多個線圈,且每一線圈包含導線之複數個單一迴路。可藉助於第11及12圖更好地理解繞組10之結構。 Winding 10 includes two sections for each phase U, V, W. The two sections with each phase are 180[deg.] (el) opposite. Each of the segments includes one or more coils, and each coil includes a plurality of single loops of wires. The structure of the winding 10 can be better understood by means of Figures 11 and 12.
第11圖在平面圖中例示導線之六角形迴路2的空間佈置,展示出每一線圈用僅一個迴路。在圖式中亦展示單一迴路之間距 p 。 Figure 11 illustrates the spatial arrangement of the hexagonal loop 2 of the wire in plan view, showing that only one loop is used per coil. The distance between single circuits p is also shown in the figure.
第12圖例示繞組10之結構,其中每一區段11包含例如兩個線圈12,且每一線圈12由複數個迴路2組成。相U、V、W之線圈在圖式中用符號A、B、C來習知地表示。 Fig. 12 illustrates the structure of the winding 10, wherein each segment 11 comprises, for example, two coils 12, and each coil 12 is composed of a plurality of loops 2. The coils of the phases U, V, and W are conventionally represented by symbols A, B, and C in the drawings.
第12圖中所用之負號係用於表示導線之繞組的相反方向。實際上,每一區段11可包含較高數量的線圈12。 The minus sign used in Figure 12 is used to indicate the opposite direction of the windings of the wires. In fact, each segment 11 can contain a higher number of coils 12.
具每一相之兩個區段11呈180°相對,如圖式中的相U之連接A與一A之間所示。圖式亦例示出:連續相之間的角距離(偏移) w ,該角距離在此實例中為60°且更一般而言對於n相繞組為360/(2n);以及疊繞組之線圈的開口 p 。距離 w 取於線圈12之中心之間或線圈組之中心之間。 The two sections 11 of each phase are 180° opposite, as shown by the connection A and A of the phase U in the figure. The figure also exemplifies the angular distance (offset) w between successive phases, which is 60° in this example and more generally 360/(2n) for the n-phase winding; and the coil of the stacked winding The opening p . The distance w is taken between the centers of the coils 12 or the center of the coil set.
線圈12之間距(或開口寬度) p 可定義為正中迴路13之軸向側面之間的距離,如第12圖之虛線所示。 The spacing (or opening width) p between the coils 12 can be defined as the distance between the axial sides of the centering circuit 13, as indicated by the dashed line in Figure 12.
根據本發明之較佳特徵,間距 p 減小至小於180°(el),較佳地為約100°(el)。較短間距之優點為,使迴路之間的交叉相應減小,如第10圖所示。 According to a preferred feature of the invention, the pitch p is reduced to less than 180 (el), preferably about 100 (el). The advantage of shorter spacing is that the crossover between the loops is correspondingly reduced, as shown in Figure 10.
第13及14圖例示繞組10之如上文定義的根據平面P1及P2之截面。 Figures 13 and 14 illustrate cross sections of the winding 10 as defined above in accordance with planes P1 and P2.
第13圖展示形成繞組10之線圈的多個同心層。第一(最內)層包含區域7U、7V、7W,第二層包含區域7’U、7’V、7’W,等等。 Figure 13 shows a plurality of concentric layers forming the coils of winding 10. The first (innermost) layer contains regions 7 U , 7 V , 7 W , and the second layer contains regions 7′ U , 7′ V , 7′ W , and so on.
第14圖例示交叉區域5之截面區域8,亦即8UV、8UW及8VW。 Figure 14 illustrates the cross-sectional area 8 of the intersection region 5, namely 8 UV , 8 UW and 8 VW .
第15圖以包含五個相的多相無心繞組展示本發明之實例,該多相無心繞組可用於例如直流(DC)馬達中。當相中之每一者包含兩個相對線圈時,在此情況下,偏移為36°(el)。 Figure 15 shows an example of the invention with a multi-phase, uncentered winding comprising five phases that can be used, for example, in a direct current (DC) motor. When each of the phases contains two opposing coils, in this case the offset is 36° (el).
第16圖展示根據位於側面3之同軸區域中之平面的第15圖之繞組的截面(第一層),且第17圖展示根據經過交叉區域5中之一者的平面之截面。該等截面展示如上所述之區域7、8。 Fig. 16 shows a section (first layer) of the winding according to Fig. 15 of the plane located in the coaxial region of the side face 3, and Fig. 17 shows a section according to the plane passing through one of the intersecting regions 5. The cross sections show the regions 7, 8 as described above.
