 この明細書における開示は、回転電機に関する。 The disclosure in this specification relates to a rotating electrical machine.
 特許文献1は、内燃機関用回転電機と、その電極を開示する。電極は、回転電機のためのコイルと、ワイヤハーネスとを接続するために利用されている。電極は、はんだ付けのための端子と、プロジェクション溶接のための端子とを備えている。特許文献2は、熱かしめのための端子を開示する。特許文献3は、ひとつの突出部分の上に、複数のコイル端がプロジェクション溶接された回転電機を開示している。 Patent Document 1 discloses a rotating electrical machine for an internal combustion engine and its electrodes.

 特許文献1または特許文献2の技術では、ひとつの電極と、ひとつのコイル端とが接続されている。これでは、回転電機の上に、多数の電極を配置する必要があり、コンパクトな回転電機の提供が困難である。 In the technique of Patent Document 1 or Patent Document 2, one electrode and one coil end are connected. In this case, it is necessary to arrange a large number of electrodes on the rotating electrical machine, and it is difficult to provide a compact rotating electrical machine.
 特許文献3の技術では、ひとつの連続した突出部分が用いられるから、長い突出部分を形成するために、大きい端子が必要となる。しかも、長い突出部分は、回転電機の端面上に長く延在するから、回転電機の上における広い範囲を占有する。別の観点では、ひとつの連続した突出部分は、複数のコイル端において順に接合作業を行う場合に不具合を生じる。ひとつの連続した突出部分において順に実行される複数の接合作業は、接合条件を徐々に変化させる。例えば、前の接合作業における温度より、後の接合作業における温度が高くなる場合がある。また、前の接合作業における飛散物が、後の接合作業に影響する場合がある。 In the technique of Patent Document 3, since one continuous protruding portion is used, a large terminal is required to form a long protruding portion. In addition, since the long protruding portion extends long on the end face of the rotating electrical machine, it occupies a wide range on the rotating electrical machine. From another viewpoint, one continuous protruding portion causes a problem when joining operations are sequentially performed at a plurality of coil ends. A plurality of joining operations executed in sequence on one continuous protruding portion gradually change the joining conditions. For example, the temperature in the subsequent bonding operation may be higher than the temperature in the previous bonding operation. In addition, scattered matter in the previous joining operation may affect the subsequent joining operation.
 上述の観点において、または言及されていない他の観点において、回転電機にはさらなる改良が求められている。 In the above-mentioned viewpoints or other viewpoints not mentioned, further improvements are demanded for rotating electrical machines.
 開示されるひとつの目的は、複数のコイル端との接続が可能な電極を備える回転電機を提供することである。 One object disclosed is to provide a rotating electrical machine including an electrode that can be connected to a plurality of coil ends.
 開示される他のひとつの目的は、複数の接合部において高品質の接合を実現できる電極を備える回転電機を提供することである。 Another object of the disclosure is to provide a rotating electrical machine including an electrode that can realize high-quality bonding at a plurality of bonding portions.
 ここに開示された回転電機は、回転電機のコイル(33)の端部である複数のコイル端(33a)と、複数のコイル端と接合される複数の端子(51、52、54)を有する電極(50、250、350、450、550、650、750、850、950、A50、C50)とを備えており、複数の端子は、回転電機において互いに離れて位置づけられており、複数のコイル端と複数の端子とは、ひとつのコイル端がひとつの端子に接合されるように一対一に接合されている。 The rotating electrical machine disclosed herein has a plurality of coil ends (33a) that are ends of a coil (33) of the rotating electrical machine, and a plurality of terminals (51, 52, 54) joined to the plurality of coil ends. Electrodes (50, 250, 350, 450, 550, 650, 750, 850, 950, A50, C50), and a plurality of terminals are positioned apart from each other in the rotating electrical machine, and a plurality of coil ends The plurality of terminals are joined one-on-one so that one coil end is joined to one terminal.
 開示される回転電機によると、複数のコイル端が電極を経由して電気的に接続される。端子が離れて配置されており、しかも、ひとつのコイル端がひとつの端子に接合されるから、高品質の接合が得られる。 According to the disclosed rotating electrical machine, a plurality of coil ends are electrically connected via electrodes. Since the terminals are arranged apart from each other and one coil end is joined to one terminal, a high-quality joint can be obtained.

The rotating electrical machine 10 includes a rotor 21 and a stator 31. In the following description, the term “axial direction” refers to a direction along the central axis when the rotor 21, the stator 31, or the stator core 32 is regarded as a cylinder. The term “radial direction” refers to a radial direction when the rotor 21, the stator 31, or the stator core 32 is regarded as a cylinder.
 ロータ21は、界磁子である。ステータ31は、電機子である。ロータ21は、全体がカップ状である。ロータ21は、回転軸14の端部に接続されている。ロータ21は、回転軸14とともに回転する。ロータ21とステータ31との径方向および軸方向の間には隙間が形成されている。回転電機10をコンパクトに構成するために、ステータ31に関連する隙間は小さいことが望ましい。ロータ21は、カップ状のロータコア22を有する。ロータコア22は、後述する永久磁石のためのヨークを提供する。ロータコア22は、磁性金属製である。ロータ21は、ロータコア22の内面に配置された永久磁石23を有する。ロータ21は、永久磁石23によって界磁を提供する。さらに、永久磁石23は、点火制御のための基準位置信号を提供するための部分的な特殊磁極を提供する。 The rotor 21 is a field element. The stator 31 is an armature. The entire rotor 21 is cup-shaped. The rotor 21 is connected to the end of the rotating shaft 14. The rotor 21 rotates together with the rotating shaft 14. A gap is formed between the rotor 21 and the stator 31 in the radial direction and the axial direction. In order to make the rotary electric machine 10 compact, it is desirable that the gap related to the stator 31 is small. The rotor 21 has a cup-shaped rotor core 22. The rotor core 22 provides a yoke for a permanent magnet described later. The rotor core 22 is made of a magnetic metal. The rotor 21 has a permanent magnet 23 disposed on the inner surface of the rotor core 22. The rotor 21 provides a field by a permanent magnet 23.

The stator 31 is disposed so as to face the rotor 21. The stator 31 has a stator core 32. The stator core 32 is provided by a laminate of magnetic metals such as electromagnetic steel plates. The stator core 32 is fixed to the body 13 of the internal combustion engine 12. The stator 31 has a stator coil 33 wound around a stator core 32. The stator coil 33 provides an armature winding. The stator coil 33 is a single-phase winding or a multi-phase winding. The stator coil 33 can selectively function the rotor 21 and the stator 31 as a generator or an electric motor. The coil wire is a single wire conductor covered with an insulating coating. The coil wire is made of an aluminum-based metal such as aluminum or an aluminum alloy.
 回転電機10は、回転電機10と電気回路11との間における電気的な接続を提供するワイヤハーネス15を有する。ワイヤハーネス15は、コイル線よりも可撓性に優れた電線である。ワイヤハーネス15は、複数の電線を含む。それぞれの電線は、複数の細線の束を樹脂製の被覆によって覆った被覆導線である。それぞれの細線は、銅系金属製またはアルミ系金属製である。 The rotating electrical machine 10 has a wire harness 15 that provides an electrical connection between the rotating electrical machine 10 and the electric circuit 11. The wire harness 15 is an electric wire that is more flexible than the coil wire. The wire harness 15 includes a plurality of electric wires. Each electric wire is a coated conductor in which a bundle of a plurality of thin wires is covered with a resin coating. Each thin wire is made of copper-based metal or aluminum-based metal.
 ワイヤハーネス15は、ステータコイル33と電気回路11とを接続する複数の電力線を含む。電気回路11は電力線が接続される外部回路である。電力線は、回転電機10が発電機として機能するとき、ステータコイル33に誘導される電力を電気回路11に供給する。電力線は、回転電機10が電動機として機能するとき、ステータコイル33を励磁するための電力を電気回路11からステータコイル33へ供給する。 The wire harness 15 includes a plurality of power lines that connect the stator coil 33 and the electric circuit 11. The electric circuit 11 is an external circuit to which a power line is connected. The electric power line supplies the electric circuit 11 with electric power induced in the stator coil 33 when the rotating electrical machine 10 functions as a generator. The power line supplies power for exciting the stator coil 33 from the electric circuit 11 to the stator coil 33 when the rotating electrical machine 10 functions as an electric motor.
 図2において、ステータ31は、外突極型のステータである。ステータコア32は、複数の磁極32aを有する。ひとつの磁極32aには、ひとつの単コイルが装着されている。ステータコイル33は、複数の単コイルによって提供されている。磁極32aは、突極またはティースとも呼ばれる。ステータコア32は、中央環状部32bを有する。中央環状部32bの径方向外側には、複数の磁極32aが設けられている。中央環状部32bの中央部には、貫通穴32cが区画されている。貫通穴32cは、ボディ12との嵌め合いのために利用される。例えば、貫通穴32cの端部とボディ12とはインロー嵌合されている。貫通穴32cは、ロータ21のボス部との干渉を回避するために利用される。貫通穴32cに求められる機能は、中央環状部32bの主として内径を制限する。また、中央環状部32bの外径は磁極32aによって制限されている。このため、中央環状部32bの大きさには制限がある。ステータコア32は、ステータコア32をボディ13に固定するための複数のボルト穴32dを有する。複数のボルト穴32dも、中央環状部32bの広さを制限する要因のひとつである。複数のボルト穴32dにより、中央環状部32bが提供しうる電極設置可能範囲は、多くの場合に扇状に制限される。 In FIG. 2, the stator 31 is an outer salient pole type stator. The stator core 32 has a plurality of magnetic poles 32a. One single coil is mounted on one magnetic pole 32a. The stator coil 33 is provided by a plurality of single coils. The magnetic pole 32a is also called a salient pole or a tooth. The stator core 32 has a central annular portion 32b. A plurality of magnetic poles 32a are provided on the radially outer side of the central annular portion 32b. A through hole 32c is defined in the central portion of the central annular portion 32b. The through hole 32 c is used for fitting with the body 12. For example, the end portion of the through hole 32c and the body 12 are inlay-fitted. The through hole 32 c is used to avoid interference with the boss portion of the rotor 21. The function required for the through hole 32c mainly limits the inner diameter of the central annular portion 32b. Further, the outer diameter of the central annular portion 32b is limited by the magnetic pole 32a. For this reason, the size of the central annular portion 32b is limited.

 図3は、ステータコイル33の結線を示す回路図である。ステータコイル33は、三相巻線である。ステータコイル33は、中性点NTを有するスター結線である。ひとつの相は、複数のコイルの並列回路によって提供されている。この例では、2つのコイルの並列接続によってひとつの相が提供されている。例えば、U相は、コイルU1とコイルU2との並列接続によって提供されている。ステータコイル33は、複数のコイルを有している。それぞれのコイルは、2つのコイル端33aを有する。よって、ステータコイル33は、複数のコイル端33aを有している。 FIG. 3 is a circuit diagram showing the connection of the stator coil 33. The stator coil 33 is a three-phase winding. Stator coil 33 is a star connection having a neutral point NT. One phase is provided by a parallel circuit of a plurality of coils.

 コイルU1は単一のコイルから形成されていても良い。これに代えて、コイルU1は、複数のコイルが直列に接続されたコイル群から形成されていても良い。例えば、ひとつの磁極32aにひとつの単コイルが装着されている場合、ひとつのコイルU1は、直列に配置された複数の単コイルの群によって提供できる。例えば、ステータ31の磁極32aが全部で18個ある場合を考える。この場合、U相に属するコイル(単コイル)は6つとなる。コイルU1とコイルU2とのそれぞれに、3つのコイルが直列接続されたコイル群が対応付けられる。この場合、コイルU1は、直列接続された3つの単コイルを含むひとつのコイル群によって提供される。例えば、コイルU1は、コイルの巻き始めと巻き終わりに1つずつ、合計2つのコイル端を有する。つまり、コイルU1とコイルU2を足し合わせたU相全体で見ると、ひとつのU相は、4つのコイル端末を有している。 The coil U1 may be formed from a single coil. Instead of this, the coil U1 may be formed of a coil group in which a plurality of coils are connected in series. For example, when one single coil is attached to one magnetic pole 32a, one coil U1 can be provided by a group of a plurality of single coils arranged in series. For example, consider a case where there are a total of 18 magnetic poles 32 a of the stator 31. In this case, there are six coils (single coils) belonging to the U phase. A coil group in which three coils are connected in series is associated with each of the coil U1 and the coil U2.

 ステータ31を製造する工程は、複数のコイル端33aのそれぞれを、対応する端子51、52に接合する工程を含む。この工程において、コイル端33aと端子51、52とは、溶接によって接合される。ここでは、端子51における溶接工程を説明する。端子52においても同様の工程が実行される。まず、1本のコイル端33aが、ひとつの突部51aの上に位置づけられる。コイル端33aは、突部51aの長手方向と交差するように位置づけられる。 The step of manufacturing the stator 31 includes a step of joining each of the plurality of coil ends 33 a to the corresponding terminals 51 and 52. In this step, the coil end 33a and the terminals 51 and 52 are joined by welding. Here, the welding process in the terminal 51 will be described. A similar process is performed at the terminal 52. First, one coil end 33a is positioned on one protrusion 51a. The coil end 33a is positioned so as to intersect the longitudinal direction of the protrusion 51a.
 次に、溶接電極65、66が、コイル端33aと、端子51との両側に位置づけられる。溶接電極65、66は、コイル端33aと端子51とを互いに押し付けるよう、締付装置によって締め付けられる。溶接電極65、66によって、突部51aはコイル端33aに食い込み、コイル端33aを変形させる。コイル端33aは、突部51aを受け入れ、接合面51bに沿うように変形する。この結果、コイル端33aと端子51とは広い面積にわたって接触する。このとき、コイル端33aの表面に酸化皮膜などの絶縁皮膜があっても、コイル端33aの変形によって絶縁皮膜が破れ、アルミニウム系金属の新鮮な表面と接合面51bとの接触が得られる場合がある。 Next, the welding electrodes 65 and 66 are positioned on both sides of the coil end 33 a and the terminal 51. The welding electrodes 65 and 66 are tightened by a tightening device so as to press the coil end 33a and the terminal 51 together. By the welding electrodes 65 and 66, the protrusion 51a bites into the coil end 33a and deforms the coil end 33a. The coil end 33a receives the protrusion 51a and deforms along the joint surface 51b. As a result, the coil end 33a and the terminal 51 are in contact with each other over a wide area. At this time, even if there is an insulating film such as an oxide film on the surface of the coil end 33a, the insulating film is broken by the deformation of the coil end 33a, and a contact between the fresh surface of the aluminum-based metal and the bonding surface 51b may be obtained. is there.
 コイル端33aは、溶接電極65、66がコイル端33aと端子51とを締め付ける過程において、突部51a、52aを包み込む形状を与えられる。コイル端33aは、溶接された後も、突部51a、52aを包み込む形状を維持している。 The coil end 33 a is given a shape that wraps the protrusions 51 a and 52 a in the process in which the welding electrodes 65 and 66 tighten the coil end 33 a and the terminal 51. Even after the coil end 33a is welded, the coil end 33a maintains a shape for enveloping the protrusions 51a and 52a.
 溶接電極65、66が締め付けられる過程の少なくとも一部において、溶接電極65、66には、溶接用電力が供給される。コイル端33aと端子51とを通して電流が流れ、コイル端33aと端子51との接触部分が発熱する。この結果、少なくとも冶金学的な拡散によってコイル端33aと端子51とが接合される。十分な発熱が得られる場合、コイル端33aの一部が溶融する。次に、溶接電極65、66が取り除かれる。比較的柔らかいコイル端33aの表面には、溶接電極65、66との接触痕が残される。コイル端33aと端子51との間の接合部には、溶接痕が残される。 The welding power is supplied to the welding electrodes 65 and 66 in at least a part of the process in which the welding electrodes 65 and 66 are tightened. A current flows through the coil end 33a and the terminal 51, and a contact portion between the coil end 33a and the terminal 51 generates heat. As a result, the coil end 33a and the terminal 51 are joined by at least metallurgical diffusion. When sufficient heat generation is obtained, a part of the coil end 33a is melted. Next, the welding electrodes 65 and 66 are removed. Contact marks with the welding electrodes 65 and 66 are left on the surface of the relatively soft coil end 33a. A welding mark is left at the joint between the coil end 33a and the terminal 51.
 ひとつのコイル端33aとひとつの端子51、52とが接合されるとき、スパッタ、煙などの高温に起因する異物が生じることがある。例えば、スパッタは、接合面51b、52bに沿って、言い換えると溶接電極65、66の間の隙間に沿って飛散する。また、高温に起因して発生する煙、揮発成分などの異物も、端子51、52の接合面に沿って、言い換えると溶接電極65、66の間の隙間に沿って広がり、飛散する。 When one coil end 33a and one terminal 51, 52 are joined, foreign matter due to high temperature such as spatter and smoke may be generated. For example, the spatter is scattered along the bonding surfaces 51b and 52b, in other words, along the gap between the welding electrodes 65 and 66. In addition, foreign matters such as smoke and volatile components generated due to high temperature also spread and scatter along the joint surfaces of the terminals 51 and 52, in other words, along the gap between the welding electrodes 65 and 66.
 この実施形態では、ひとつの端子51における接合工程の後に、他の端子52における接合工程が実行される。端子52における接合工程の後に、端子51における接合工程が実行されてもよい。 In this embodiment, after the joining process at one terminal 51, the joining process at another terminal 52 is executed. After the joining process at the terminal 52, the joining process at the terminal 51 may be performed.
 端子51すなわちタブ57は、ステータ31の径方向に沿って広がっている。一方、端子52すなわちタブ58も、ステータ31の径方向に沿って広がっている。よって、先に接合工程が実行される接合面51b、52bの延長上に、後に接合工程が実行される接合面51b、52bが位置していない。このため、先の接合工程において発生した飛散物は、後の接合工程の対象である接合面51b、52bに到達しにくい。このため、先行する接合工程における飛散物に起因する接合状態の悪化が抑制される。 The terminal 51, that is, the tab 57 extends along the radial direction of the stator 31. On the other hand, the terminal 52, that is, the tab 58 also extends along the radial direction of the stator 31. Therefore, the joining surfaces 51b and 52b on which the joining process is performed later are not positioned on the extension of the joining surfaces 51b and 52b on which the joining process is performed first. For this reason, the scattered matter generated in the previous joining step is unlikely to reach the joining surfaces 51b and 52b that are the targets of the subsequent joining step. For this reason, the deterioration of the joining state resulting from the scattered material in the preceding joining process is suppressed.
 タブ57とタブ58との間には、タブ56が設けられている。タブ57の上、すなわち端子51における接合工程で生じた熱は、タブ56を通して、タブ58に到達する。しかし、タブ56が幅方向WDに延びているから、熱伝導が抑制される。よって、端子51において生じた熱に起因する端子52の温度上昇が抑制される。この結果、端子51における接合工程でのパラメータと、端子52における接合工程でのパラメータと差を抑制することができる。例えば、端子51における接合工程と、端子52における接合工程とに、同じ工程パラメータを利用することができる。例えば、溶接電極65、66による締め付け圧、締め付け時間、通電量などの差を減らすことができる。別の観点では、2つの端子51、52における温度差が抑制されるから、接合部の品質の差が抑制される。 The tab 56 is provided between the tab 57 and the tab 58. The heat generated in the joining process on the tab 57, that is, in the terminal 51 reaches the tab 58 through the tab 56. However, since the tab 56 extends in the width direction WD, heat conduction is suppressed. Therefore, the temperature rise of the terminal 52 due to the heat generated in the terminal 51 is suppressed. As a result, it is possible to suppress a difference between the parameter in the joining process at the terminal 51 and the parameter in the joining process at the terminal 52. For example, the same process parameters can be used for the bonding process at the terminal 51 and the bonding process at the terminal 52. For example, it is possible to reduce differences in tightening pressure, tightening time, energization amount, and the like due to the welding electrodes 65 and 66. From another viewpoint, since the temperature difference between the two terminals 51 and 52 is suppressed, the difference in quality of the joint is suppressed.
 この実施形態では、図示されるすべての端子51、52が、ステータ31上において径方向に広がっている。言い換えると、すべての端子51、52は、放射状に配置されている。よって、溶接電極65、66は、すべての端子51、52において周方向または接線方向への開閉動作によって溶接作業が可能である。また、ステータ31の周方向に沿って、ステータ31または溶接電極65、66を移動させることにより、複数の端子51、52における接合作業が可能である。 In this embodiment, all the terminals 51 and 52 shown in the figure are spread radially on the stator 31. In other words, all the terminals 51 and 52 are arranged radially. Therefore, the welding electrodes 65 and 66 can be welded by opening and closing operations in the circumferential direction or tangential direction at all the terminals 51 and 52. Further, by moving the stator 31 or the welding electrodes 65 and 66 along the circumferential direction of the stator 31, it is possible to join the plurality of terminals 51 and 52.
 ステータ31を製造する工程は、ワイヤハーネス15を端子53に接続する工程を含む。この工程では、ワイヤハーネス15の導体15aが、端子53の一対の爪の間に配置される。次に、導体15aと端子53とに溶融状態のはんだ62が付与される。はんだ62が固化することにより、はんだ62の塊が形成される。ことによりワイヤハーネス15と端子53とのはんだ付が完了する。はんだ62を付与する前に、導体15aを締め付けるように一対の爪を変形させ、導体15aを仮固定してもよい。端子53における工程は、端子51、52における接合工程の前に、または後に実行することができる。 The step of manufacturing the stator 31 includes a step of connecting the wire harness 15 to the terminal 53. In this step, the conductor 15 a of the wire harness 15 is disposed between the pair of claws of the terminal 53. Next, molten solder 62 is applied to the conductor 15 a and the terminal 53. When the solder 62 is solidified, a lump of the solder 62 is formed. This completes the soldering of the wire harness 15 and the terminal 53. Before applying the solder 62, the pair of claws may be deformed so as to tighten the conductor 15a, and the conductor 15a may be temporarily fixed. The process at the terminal 53 can be performed before or after the bonding process at the terminals 51 and 52.
 ステータ31を製造する工程は、端子51、52における接合工程の後に、保護部材61を付与する工程を含む。保護部材61は、端子51、52の上に、流動可能な状態の樹脂を塗布または滴下することによって付与される。保護部材61は、樹脂を硬化させることによって形成されている。さらに、コイル端33aおよび端子51、52を覆うように、ステータコイル33を覆うワニスなどの樹脂材料を付与してもよい。 The step of manufacturing the stator 31 includes a step of applying the protective member 61 after the joining step of the terminals 51 and 52. The protective member 61 is provided on the terminals 51 and 52 by applying or dropping a resin in a flowable state. The protection member 61 is formed by curing a resin. Further, a resin material such as a varnish for covering the stator coil 33 may be provided so as to cover the coil end 33 a and the terminals 51 and 52.
 以上に述べた実施形態によると、回転電機10の上において占める面積が小さい回転電機用の電極50、回転電機10、および回転電機10の製造方法を提供することができる。また、別の観点では、ひとつの端子における接合作業から、他のひとつの端子における接合作業への影響が抑制される。 According to the embodiment described above, it is possible to provide the rotating electrical machine electrode 50, the rotating electrical machine 10, and the manufacturing method of the rotating electrical machine 10 that occupy a small area on the rotating electrical machine 10. Moreover, from another viewpoint, the influence on the joining operation at one other terminal is suppressed from the joining operation at one terminal.

One electrode has two terminals 51 and 52 arranged in a shape that can be called L-shaped or V-shaped. The insulator 35 has a container 35 d for suppressing the flow of the protection member 61. The container 35d has a shallow dish shape. The side walls characterizing the container 35d are lower than the terminals 51,52. The side wall has a height for restricting the flow of the resin material forming the protection member 61. The plurality of electrodes 250 are disposed in the container 35d.
 電極250は、2つの端子51、52がステータ31の径方向外側に向けて開くV字型となるように配置されている。2つの接合面51b、52bは、L字型またはV字型に配置された2つの端子51、52、すなわちタブ56、57が区画する空洞の外側に面している。また、接合面51b、52bは、ステータ31上において、径方向内側に面している。2つの接合面51b、52bは、互いにタブ56、57の裏側または陰に位置している。 The electrode 250 is arranged so that the two terminals 51 and 52 are V-shaped and open toward the outside in the radial direction of the stator 31. The two joint surfaces 51b and 52b face the outside of the cavity defined by the two terminals 51 and 52, that is, the tabs 56 and 57 arranged in an L shape or a V shape. Further, the joint surfaces 51 b and 52 b face radially inward on the stator 31. The two joint surfaces 51b and 52b are located behind or behind the tabs 56 and 57, respectively.
 コイル端33aは、ステータ31の径方向外側から、径方向内側に向けて延びるように配置されている。コイル端33aは、端子51、52に巻き付くように配置されている。 The coil end 33a is disposed so as to extend from the radially outer side of the stator 31 toward the radially inner side. The coil end 33 a is disposed so as to be wound around the terminals 51 and 52.
 図9、図10、図11は、図5、図6、図7に対応する図である。電極250は、タブ56に端子52を有する。よって、2つのタブ56、57、および2つの端子51、52は、L字型、またはV字型と呼びうる形状をなすように配置されている。 9, FIG. 10, and FIG. 11 are diagrams corresponding to FIG. 5, FIG. 6, and FIG. The electrode 250 has a terminal 52 on a tab 56. Therefore, the two tabs 56 and 57 and the two terminals 51 and 52 are arranged to form a shape that can be called an L-shape or a V-shape.
 電極250は、端子51と端子52との間、言い換えるとタブ56とタブ57との間に凹部56cを有する。タブ56とタブ57との間には、それらを連結する部分が残されている。凹部56cは、端子51、52の軸方向における先端側から、長さ方向LDに沿って延びている。凹部56cは、端子51と端子52とを分離する。凹部56cによって、端子51と端子52との間における熱伝導を抑制する熱障壁部が提供される。凹部56cは、複数の接合面51b、52bの間に位置している。凹部56cは、熱伝導に寄与する断面積を抑制する。凹部56cにより、端子51は、長さ方向LDに独立して突出した単独端子を提供する。端子52も、単独端子を提供する。 The electrode 250 has a recess 56 c between the terminal 51 and the terminal 52, in other words, between the tab 56 and the tab 57. A portion connecting the tab 56 and the tab 57 is left. The recess 56c extends along the length direction LD from the distal end side in the axial direction of the terminals 51 and 52. The recess 56 c separates the terminal 51 and the terminal 52. The recess 56c provides a thermal barrier portion that suppresses heat conduction between the terminal 51 and the terminal 52. The recess 56c is located between the plurality of bonding surfaces 51b and 52b. The recess 56c suppresses a cross-sectional area that contributes to heat conduction. By the recess 56c, the terminal 51 provides a single terminal protruding independently in the length direction LD. Terminal 52 also provides a single terminal.

 タブ57は、先行する実施形態よりやや長く高さ方向HDへ延び出している。同時に、凹部56cは、高さ方向HDに沿ってやや広く延びている。これにより、端子51と端子52との間における熱伝導が抑制される。 The tab 57 extends in the height direction HD slightly longer than the preceding embodiment. At the same time, the recess 56c extends slightly wider along the height direction HD. Thereby, the heat conduction between the terminal 51 and the terminal 52 is suppressed.

 電極650において、タブ56とタブ57とは、同一の平面上に広がる板状部分である。タブ57は、タブ56の幅方向WDの一方に突出している。電極650は、L字型と呼びうる幅方向WDに関して非対称の形状をもつ。 In the electrode 650, the tab 56 and the tab 57 are plate-like portions extending on the same plane. The tab 57 protrudes to one side of the tab 56 in the width direction WD. The electrode 650 has an asymmetric shape with respect to the width direction WD, which can be called L-shaped.
 タブ56の上に端子52が設けられている。タブ57の上に端子51が設けられている。突部51aと突部52aとは、高さ方向HDにおける反対の方向に向けて突出している。よって、接合面51bと接合面52bとは、高さ方向HDに関して反対の方向に面している。複数の接合面51b、52bのそれぞれは、板状の部材の表裏それぞれに配置されている。 A terminal 52 is provided on the tab 56. A terminal 51 is provided on the tab 57. The protrusion 51a and the protrusion 52a protrude in the opposite direction in the height direction HD.

 第7実施形態
 この実施形態は、先行する実施形態を基礎的形態とする変形例である。図24、図25、図26は、図5、図6、図7に対応する図である。
Seventh Embodiment This embodiment is a modified example based on the preceding embodiment. 24, 25, and 26 correspond to FIGS. 5, 6, and 7. FIG.
 電極750は、タブ56の上に形成された突部52aと、タブ57の上に形成された突部51aとを有する。突部51a、52aは高さ方向HDに関して同じ方向に突出している。接合面51bと、接合面52bとは、高さ方向HDに関して同じ方向に面している。 The electrode 750 has a protrusion 52 a formed on the tab 56 and a protrusion 51 a formed on the tab 57. The protrusions 51a and 52a protrude in the same direction with respect to the height direction HD. The joint surface 51b and the joint surface 52b face in the same direction with respect to the height direction HD.
 複数の突部51a、52aの間には平板状の部分が広がっている。複数の突部51a、52aは、互いに離れている。複数の突部51a、52aは、ステータ31の上においても離れて位置づけられる。この実施形態でも、ひとつの端子、すなわちひとつの突部にひとつのコイル端33aが接合される。しかも、複数の突部51a、52aは独立している。 A flat plate-like portion spreads between the plurality of protrusions 51a and 52a. The plurality of protrusions 51a and 52a are separated from each other. The plurality of protrusions 51 a and 52 a are also positioned apart on the stator 31. Also in this embodiment, one coil end 33a is joined to one terminal, that is, one protrusion. Moreover, the plurality of protrusions 51a and 52a are independent.
 回転電機10の製造方法において、複数の端子51、52にわたって広がる共通の溶接電極65、66が用いられる。この製造方法でも、一連の接合工程によって、2つの端子51、52における接合を提供できる。なお、溶接電極65、66のいずれか少なくとも一方に代えて、ひとつの端子にだけ対応付けられた溶接電極が利用されてもよい。この場合、端子51における接合工程と、端子52における接合工程とは、順に実行される。 In the manufacturing method of the rotating electrical machine 10, common welding electrodes 65 and 66 extending over the plurality of terminals 51 and 52 are used. Even in this manufacturing method, the joining at the two terminals 51 and 52 can be provided by a series of joining steps. Instead of at least one of the welding electrodes 65 and 66, a welding electrode associated with only one terminal may be used. In this case, the joining process at the terminal 51 and the joining process at the terminal 52 are performed in order.
 この実施形態でも、回転電機10の上において占める面積が小さい回転電機用の電極650が提供される。よって、ひとつの電極750における複数の接合部を高い品質で形成することができる。 Also in this embodiment, an electrode 650 for a rotating electrical machine that occupies a small area on the rotating electrical machine 10 is provided. Therefore, a plurality of joints in one electrode 750 can be formed with high quality.
 第8実施形態
 この実施形態は、先行する実施形態を基礎的形態とする変形例である。図27、図28、図29は、図5、図6、図7に対応する図である。
Eighth Embodiment This embodiment is a modification example based on the preceding embodiment. 27, 28, and 29 are diagrams corresponding to FIG. 5, FIG. 6, and FIG.
 電極850は、ボディ部55の一端に端子52を有し、ボディ部55の他端に端子51を有する。電極850は、ボディ部55の一端に端子53を有する。端子53は、タブ57の上に配置されている。端子51は、タブ59の上に配置されている。突部51aと突部52aとは、高さ方向HDにおける同じ方向に向けて突出している。よって、接合面51bと接合面52bとは、同じ方向に面している。 The electrode 850 has a terminal 52 at one end of the body portion 55 and a terminal 51 at the other end of the body portion 55. The electrode 850 has a terminal 53 at one end of the body portion 55. The terminal 53 is disposed on the tab 57. The terminal 51 is disposed on the tab 59. The protrusion 51a and the protrusion 52a protrude in the same direction in the height direction HD. Therefore, the joint surface 51b and the joint surface 52b face in the same direction.
 この実施形態では、端子51と端子52とがステータ31の両端面の上に隔絶して配置される。これにより、端子51における接合作業と端子52における接合作業との悪影響が抑制される。端子53は、接合面52bの延長上にないタブ57の上に形成されているから、端子52における接合作業から受ける影響が抑制される。 In this embodiment, the terminal 51 and the terminal 52 are disposed on both end surfaces of the stator 31 so as to be isolated from each other. Thereby, the bad influence of the joining work in the terminal 51 and the joining work in the terminal 52 is suppressed. Since the terminal 53 is formed on the tab 57 which is not on the extension of the joining surface 52b, the influence received from the joining work on the terminal 52 is suppressed.
 この実施形態でも、回転電機10の上において占める面積が小さい回転電機用の電極850が提供される。この実施形態でも、高い品質の複数の接合部を形成可能な電極850が提供される。 Also in this embodiment, an electrode 850 for a rotating electrical machine that occupies a small area on the rotating electrical machine 10 is provided. This embodiment also provides an electrode 850 capable of forming a plurality of high quality joints.
