溶接で接続せずに直接コイルを這い回す方法では、這い回す口出しコイルが長くなり、後工程で干渉が起こるため、このように最終工程で溶接によって取り付ける方法が取られている。 In the method in which the coil is directly wound around without being connected by welding, the lead coil to be wound around becomes long and interference occurs in the subsequent process. Thus, the method of attaching by welding in the final process is employed.
回転電機の運転時などに、振動や冷熱などにより口出しコイルとコイルの溶接部に応力が発生し、変形や破損が生じる可能性がある。 During operation of the rotating electrical machine, stress may be generated in the lead coil and the welded portion of the coil due to vibration, cold heat, etc., and deformation or breakage may occur.

The present application includes a plurality of means for solving the above-described problems. For example, in the rotating electrical machine having a resin member that holds a scooping coil from a stator coil, the resin member is the scooping coil. And a fixing member that holds the lead wire connected through the welded portion.

なお、以下の説明において、「軸方向」は回転電機の回転軸に沿った方向を指す。周方向は回転電機の回転方向に沿った方向を指す。「径方向」は回転電機の回転軸を中心としたときの動径方向（半径方向）を指す。「内周側」は径方向内側（内径側）を指し、「外周側」はその逆方向、すなわち径方向外側（外径側）を指す。
［実施例１］
本実施例に係る回転電機は、自動車の走行に使用するのが好適な回転電機である。ここで、回転電機を使用するいわゆる電気自動車には、エンジンと回転電機の両方を備えるハイブリッドタイプの電気自動車（ＨＥＶ）と、エンジンを用いないで回転電機のみで走行する純粋な電気自動車（ＥＶ）とがあるが、以下に説明する回転電機は両方のタイプに利用できるので、ここでは代表してハイブリッドタイプの自動車に用いられる回転電機に基づいて説明する。

The “radial direction” refers to a radial direction (radial direction) when the rotational axis of the rotating electrical machine is the center. “Inner circumference side” refers to the radially inner side (inner diameter side), and “outer circumference side” refers to the opposite direction, that is, the radially outer side (outer diameter side).
[Example 1]
The rotating electrical machine according to the present embodiment is a rotating electrical machine that is suitable for use in driving an automobile. Here, a so-called electric vehicle using a rotating electric machine includes a hybrid type electric vehicle (HEV) having both an engine and a rotating electric machine, and a pure electric vehicle (EV) that runs only by the rotating electric machine without using an engine. However, since the rotating electrical machine described below can be used for both types, the description will be made based on the rotating electrical machine used for a hybrid type vehicle as a representative.
図１は、本発明の実施例に係る回転電機１００の全体構成を示す模式図である。図１では、回転電機１００の一部分を断面とすることで、回転電機１００の内部を示している。 FIG. 1 is a schematic diagram illustrating an overall configuration of a rotating electrical machine 100 according to an embodiment of the present invention. In FIG. 1, the inside of the rotating electrical machine 100 is shown by making a part of the rotating electrical machine 100 into a cross section.
回転電機１００は、図１に示すように、ケース１０の内部に配設されるものであり、ハウジング１１２と、ハウジング１１２に固定される固定子鉄心１３２を有する固定子１３０と、この固定子内に回転自在に配設される回転子１５０と、を備えている。ケース１０は、エンジンのケースや変速機のケースによって構成される。 As shown in FIG. 1, the rotating electrical machine 100 is disposed inside the case 10, and includes a housing 112, a stator 130 having a stator core 132 fixed to the housing 112, and the inside of the stator. And a rotor 150 disposed rotatably. The case 10 includes an engine case and a transmission case.
この回転電機１００は、永久磁石内蔵型の三相同期モータである。回転電機１００は、固定子鉄心１３２に巻回される固定子コイル１３８に三相交流電流が供給されることで、回転子１５０を回転させる電動機として作動する。また、回転電機１００は、エンジンによって駆動されると、発電機として作動して三相交流の発電電力を出力する。つまり、回転電機１００は、電気エネルギーに基づいて回転トルクを発生する電動機としての機能と、機械エネルギーに基づいて発電を行う発電機としての機能の両方を有しており、自動車の走行状態によって上記機能を選択的に利用することができる。 The rotating electrical machine 100 is a three-phase synchronous motor with a built-in permanent magnet. The rotating electrical machine 100 operates as an electric motor that rotates the rotor 150 when a three-phase alternating current is supplied to the stator coil 138 wound around the stator core 132. Further, when the rotating electrical machine 100 is driven by an engine, it operates as a generator and outputs three-phase AC generated power. That is, the rotating electrical machine 100 has both a function as an electric motor that generates rotational torque based on electric energy and a function as a generator that generates electric power based on mechanical energy. Functions can be used selectively.
ハウジング１１２に固定された固定子１３０は、ハウジング１１２に設けられたフランジ１１５がボルト１２によりケース１０に締結されることで、ケース１０内に固定保持されている。 The stator 130 fixed to the housing 112 is fixedly held in the case 10 by fastening a flange 115 provided on the housing 112 to the case 10 with a bolt 12.
回転子１５０は、ケース１０の軸受け１４Ａ、１４Ｂにより支承されるシャフト１１８に固定されており、固定子鉄心１３２の内側において回転可能に保持されている。 The rotor 150 is fixed to the shaft 118 supported by the bearings 14 </ b> A and 14 </ b> B of the case 10, and is rotatably held inside the stator core 132.
固定子コイル１３８は、図１に示すように、全体で３系統（Ｕ、Ｖ、Ｗ）のコイルが固定子鉄心１３２に密着して装着されている。そして、固定子コイル１３８を構成する３系統のコイルは、スロット４２０によって相互に適正な間隔をもって配列される。 As shown in FIG. 1, the stator coil 138 has a total of three systems (U, V, W) of coils mounted in close contact with the stator core 132. The three coils constituting the stator coil 138 are arranged at appropriate intervals by the slot 420.
固定子コイル１３８における一方のコイルエンドには、Ｕ、Ｖ、Ｗ三相それぞれの固定子コイル１３８の入出力用の導体である交流端子４１、４２、４３と、中性点結線用導体（図示せず）と、が引き出されている。なお、回転電機１００の組み立てにおける作業性向上のために、三相交流電力を受けるための交流端子４１、４２、４３は、コイルエンドから固定子鉄心１３２の軸方向外方に突出するように配置されている。そして、固定子１３０は、この交流端子４１、４２、４３を介して電力変換装置（図示せず）に接続されることで、交流電力が供給されるようになっている。 At one coil end of the stator coil 138, there are AC terminals 41, 42, 43, which are input / output conductors of the U, V, and W three-phase stator coils 138, and a neutral point connection conductor (see FIG. (Not shown). In order to improve workability in the assembly of the rotating electrical machine 100, the AC terminals 41, 42, 43 for receiving the three-phase AC power are arranged so as to protrude outward in the axial direction of the stator core 132 from the coil end. Has been. The stator 130 is connected to a power converter (not shown) through the AC terminals 41, 42, and 43, so that AC power is supplied.
三相交流電流が固定子コイル１３８に供給されることにより固定子１３０に回転磁界が発生すると、この回転磁界が回転子１５０の永久磁石１５４に作用して磁石トルクが発生する。つまり、回転子１５０には、この磁石トルクに加えて、上述のリラクタンストルクが発生するので、回転子１５０には上述の磁石トルクとリラクタンストルクとの両方のトルクが回転トルクとして作用し、大きな回転トルクを得ることができる。 When a rotating magnetic field is generated in the stator 130 by supplying the three-phase alternating current to the stator coil 138, the rotating magnetic field acts on the permanent magnet 154 of the rotor 150 to generate magnet torque. That is, since the reluctance torque described above is generated on the rotor 150 in addition to this magnet torque, both the above-described magnet torque and reluctance torque act on the rotor 150 as the rotational torque, resulting in a large rotation. Torque can be obtained.
次に、本発明の特徴である補強部について、図２、図３を参照して説明する。図２は、本発明の第１の実施例に係る回転電機１００の固定子１３０の一部の斜視図である。 Next, the reinforcement part which is the characteristic of this invention is demonstrated with reference to FIG. 2, FIG. FIG. 2 is a perspective view of a part of the stator 130 of the rotating electrical machine 100 according to the first embodiment of the present invention.
Ｕ、Ｖ、Ｗ三相それぞれの固定子コイル１３８の入出力用の導体である交流端子４１、４２、４３と、中性点結線用導体（図示せず）と、が引き出されている側のコイルエンドの軸方向上部に、樹脂部材５００が設けられている。樹脂部材５００には、固定子コイル１３８に電気的につながる配線５２１がモールドされている。樹脂部材５００の径方向外側には、リード線５６０を保持する固定部材５１０が設けられている。 AC terminals 41, 42, and 43, which are input / output conductors of the U, V, and W three-phase stator coils 138, and a neutral point connection conductor (not shown) are drawn out. A resin member 500 is provided on the upper part in the axial direction of the coil end. The resin member 500 is molded with a wiring 521 that is electrically connected to the stator coil 138. A fixing member 510 that holds the lead wire 560 is provided on the radially outer side of the resin member 500.
固定部材５１０の内部には、銅板５４０が樹脂モールドされている。銅板５４０は、固定部材５１０の径方向内側で軸方向に突出する第１の銅板突出部５４０Ａと、固定部材５１０の径方向外側で軸方向に突出する第２の銅板突出部５４０Ｂとを有している。固定部材５１０は、配線５２１を通すための第１の貫通孔を銅板突出部５４０Ａ付近に、リード線５６０を軸方向に通すための第２の貫通孔を銅板突出部５４０Ｂ付近に有している。 A copper plate 540 is resin-molded inside the fixing member 510. The copper plate 540 includes a first copper plate protruding portion 540A that protrudes in the axial direction on the radially inner side of the fixing member 510, and a second copper plate protruding portion 540B that protrudes in the axial direction on the radially outer side of the fixing member 510. ing. The fixing member 510 has a first through hole for passing the wiring 521 near the copper plate protruding portion 540A, and a second through hole for passing the lead wire 560 in the axial direction near the copper plate protruding portion 540B. .
第１の貫通孔を通して配線５２１の一端を、第２の貫通孔を通してリード線５６０の一端をそれぞれ引き出す。そして、配線５２１の一端と第１の銅板突出部５４０Ａの先端とを溶接し、溶接部５２０Ａを形成する。また、リード線５６０の一端と第２の銅板突出部５４０Ｂの先端とを溶接し、溶接部５２０Ｂを形成する。 One end of the wiring 521 is pulled out through the first through hole, and one end of the lead wire 560 is pulled out through the second through hole. Then, one end of the wiring 521 and the tip of the first copper plate protruding portion 540A are welded to form a welded portion 520A. Further, one end of the lead wire 560 and the tip of the second copper plate protrusion 540B are welded to form a welded portion 520B.
なお、リード線５６０は丸線だけでなく平角線でもよい。 The lead wire 560 may be not only a round wire but also a flat wire.
配線５２１（すなわち固定子からの這い回しコイル）を、固定部材５１０にモールドされた銅板５４０を介してリード線５６０と接続することにより、配線５２１とリード線５６０と固定部材５１０により保持することができ、振動や冷熱により溶接部５２０Ａ、５２０Ｂに発生する応力を低減することができる。 By connecting the wiring 521 (that is, the winding coil from the stator) to the lead wire 560 through the copper plate 540 molded on the fixing member 510, the wiring 521, the lead wire 560, and the fixing member 510 can be held. It is possible to reduce the stress generated in the welded portions 520A and 520B due to vibration and cold heat.
なお、銅板５４０は省略可能である。この場合、リード線５６０と固定子からの這い回しコイルと固定部材５１０により保持し、リード線５６０と固定子からの這い回しコイルとを直接接続すればよい。
［実施例２］
本発明の別の実施例を説明する。特に説明しない部分は実施例１と同様である。
The copper plate 540 can be omitted. In this case, the lead wire 560 and the winding coil from the stator are held by the fixing member 510, and the lead wire 560 and the winding coil from the stator may be directly connected.
[Example 2]
Another embodiment of the present invention will be described. Parts not specifically described are the same as those in the first embodiment.
本実施例では、実施例１で説明した固定部材５１０の径方向外側の端部から銅板５４０を引き出して第２の銅板突出部５４０Ｂとする。径方向に引き出された第２の銅板突出部５４０Ｂは、途中で軸方向に屈曲し、この軸方向に屈曲した部分でリード線５６０とをリング５３０で加締めた後、リード線５６０の一端と第２の銅板突出部５４０Ｂの先端とを溶接し、溶接部５２０Ｂを形成する。 In the present embodiment, the copper plate 540 is pulled out from the radially outer end of the fixing member 510 described in the first embodiment to form a second copper plate protrusion 540B. The second copper plate protrusion 540B drawn in the radial direction bends in the axial direction in the middle, and after crimping the lead wire 560 with the ring 530 at the portion bent in the axial direction, The tip of the second copper plate protrusion 540B is welded to form a weld 520B.
なお、この第２の銅板突出部５４０Ｂの軸方向への屈曲は、リード線５６０との溶接部５２０Ｂを軸方向に設け、溶接作業を容易にするために行っている。 The second copper plate protrusion 540B is bent in the axial direction in order to provide a welding portion 520B with the lead wire 560 in the axial direction to facilitate the welding operation.
リング５３０を介して接続することにより、振動や冷熱により溶接部に発生する応力を低減することができる。 By connecting via the ring 530, the stress which generate | occur | produces in a welding part by a vibration or cold heat can be reduced.
本実施例では、リング５３０は板厚０．５〜１．５ｍｍ程度の銅板の板材であるが、ろう材を貼り付けしたクラッド材でもよい。 In this embodiment, the ring 530 is a copper plate having a thickness of about 0.5 to 1.5 mm, but may be a clad material with a brazing material attached thereto.
また、実施例１と同様に銅板５４０は省略可能であり、固定子からの這い回しコイルを、リング５３０を介してリード線５６０と直接接続してもよい。 Further, the copper plate 540 can be omitted as in the first embodiment, and the scooping coil from the stator may be directly connected to the lead wire 560 through the ring 530.
溶接しやすいように固定子の軸方向と平行にリード線５６０が配置されている。溶接するときに電極が配置しやすく作業性が向上する。 Lead wires 560 are arranged in parallel with the axial direction of the stator so as to facilitate welding. When welding, the electrodes are easy to arrange and workability is improved.
溶接は溶融接合であり、主にＴＩＧ溶接やレーザ溶接などである。 Welding is fusion bonding, mainly TIG welding or laser welding.
以上説明した各実施例では、溶接部５２０Ａ、５２０Ｂの高さは、溶接部５２０Ａ毎、溶接部５２０Ｂ毎に、それぞれ３つともほぼ同じ高さであるため、同一の溶接装置で溶接することができる。また、各実施例では、固定部材５１０において固定子１３０の軸方向にリード線５６０が突出するように配置している。このように、溶接部５２０Ａ、５２０Ｂが軸方向を向くように配線５２１やリード線を配置することで、溶接するときに電極を配置しやすく、作業性を向上させることができる。 In each of the embodiments described above, the heights of the welded portions 520A and 520B are approximately the same height for each of the welded portions 520A and the welded portions 520B, so that welding can be performed with the same welding apparatus. it can. In each embodiment, the fixing member 510 is arranged so that the lead wire 560 protrudes in the axial direction of the stator 130. Thus, by arranging the wiring 521 and the lead wires so that the welded portions 520A and 520B face the axial direction, it is easy to arrange the electrodes when welding, and workability can be improved.
なお、配線５２１やリード線５６０を周方向や径方向に突出させる、すなわち溶接部５２０Ａ、５２０Ｂが周方向や径方向を向くように構成してもよい。この構成において銅板５４０を用いる場合は、配線５２１やリード線５６０の突出方向に合わせ、第１の銅板突出部５４０Ａや第２の銅板突出部５４０Ｂの突出方向や屈曲方向を周方向や径方向に変更する。 Note that the wiring 521 and the lead wire 560 may be protruded in the circumferential direction and the radial direction, that is, the welded portions 520A and 520B may be directed in the circumferential direction and the radial direction. When using the copper plate 540 in this configuration, the protruding direction and the bending direction of the first copper plate protruding portion 540A and the second copper plate protruding portion 540B are set in the circumferential direction and the radial direction in accordance with the protruding direction of the wiring 521 and the lead wire 560. change.
各実施例では、固定部材５１０を樹脂部材５００と一体成形しているが、固定部材５１０と樹脂部材５００とを別々に成形し、嵌合部などを介して接続する構成にしてもよい。また、各実施例では、固定部材５１０は樹脂部材５００と同じ絶縁材料で構成されているが、異なる絶縁材料で構成してもよい。さらに、銅板５４０は導電部材であればよく、銅製の板状部材に限るものではない。 In each embodiment, the fixing member 510 and the resin member 500 are integrally formed. However, the fixing member 510 and the resin member 500 may be formed separately and connected via a fitting portion or the like. Moreover, in each Example, although the fixing member 510 is comprised with the same insulating material as the resin member 500, you may comprise with a different insulating material. Furthermore, the copper plate 540 should just be an electroconductive member, and is not restricted to a copper plate-shaped member.
リード線５６０は固定子１３０を回転させるときなどに、治具等に干渉するおそれがあり、さらにリード線５６０が曲がってしまうおそれがある。このため、下流工程でリード線５６０と銅板５４０を接続することで、作業性を向上させることができる。また、リード線５６０を、複数の直線部および屈曲部から構成された折り曲げ構造の導体で構成することにより、用途に応じたさまざまな形に変更することができ、多機種に適用することが可能となる。 When the stator 130 is rotated, the lead wire 560 may interfere with a jig or the like, and the lead wire 560 may be bent. For this reason, workability | operativity can be improved by connecting the lead wire 560 and the copper plate 540 in a downstream process. In addition, by configuring the lead wire 560 with a conductor having a bent structure composed of a plurality of straight portions and bent portions, the lead wire 560 can be changed into various shapes depending on the application, and can be applied to various models. It becomes.
