The connection ring 5 is formed in an annular shape with an insulating material, and the conductive members 41 to 44 are disposed. The stator core 10 is formed by laminating a plurality of electromagnetic steel plates having a thickness of about 0.05 to 1.0 mm, which are formed in an annular shape by punching or etching. Thereby, the shape of the stator core 10 becomes a cylindrical shape.

The bobbin 3 is made of an insulating member, and has an effect of insulating between the stator coil 2 and the stator core 10 and transferring the heat of the stator coil 2 to the teeth portion 12. The stator coil 2 is wound around the teeth portion 12 via the bobbin 3.

  A portion extending from the slot of the concentratedly wound stator coil 2 to the slot is a coil end portion 14. In order to reduce the amount of copper used, the coil end portion is desired to be short and low in height.

  The end portion 15 of the stator coil 2 extends from the coil end portion 14 to the outside in the radial direction of the rotating electrical machine at the beginning and end of winding.

FIG. 4 is a diagram showing a common shape of the conductive members 41, 42, 43, and 44 used in the stator assembly ASSY1 of the rotating electrical machine according to the first embodiment of the present invention.

  The U-phase conductive member 41, the V-phase conductive member 42, the W-phase conductive member 43, and the neutral wire conductive member 44 each have a terminal portion 46 that is connected to the stator coil 2. The terminal portion 46 of the conductive member has a shape in which a part of a substantially cylindrical conductive member is extended in the axial direction of the stator ASSY 1. The conductive members 41 to 44 are formed, for example, by punching a rectangular metal plate and then bending it into an annular shape.

  Next, the structure of the connection part of the stator coil 2 and the electroconductive members 41-44 is demonstrated using FIGS. FIG. 5 is a diagram illustrating a configuration of a connection portion between the stator coil 2 and the conductive members 41 to 44 used in the stator assembly ASSY1 of the rotating electrical machine according to the first embodiment of the present invention. FIG. 6 is an enlarged view of the connecting portion shown in FIG.

  Specifically, as shown in FIG. 6, the end portion 15 of the stator coil 2 is in contact with the circumferential end surface 46 </ b> W of the terminal portion 46. The end 15 of the stator coil 2 extends along the radial direction of the conductive members 41 to 44 (the radial direction of the stator core 10).

  The end portion of the stator coil 2 that is in contact with the terminal portions 46 of the conductive members 41 to 44 is an insulator on the surface of the stator coil 2 for the purpose of bonding more reliable base materials in joining. The enamel film is peeled off (15b).

  Here, the volume difference between the portion 15b from which the enamel film is peeled off and the terminal portion 46 of the conductive members 41 to 44 is preferably equal to or less than a predetermined threshold value. The predetermined threshold is determined so that the peeled portion 15 and the terminal portion 46 are melted in a well-balanced manner during welding.

  The end portion 15 of the stator coil 2 and the terminal portion 46 of the conductive members 41 to 44 are connected by a method such as welding, for example, at a portion that is in contact with the substantially intersecting shape. In this embodiment, since the connection part of the stator coil 2 and the electroconductive members 41-44 is arrange | positioned not on the coil end part 14 but on the electroconductive members 41-44, in the case of a connection, the coil end part 14 is arranged. There is no concern that sparks or the like may scatter and damage the insulating coating of the stator coil 2.

  Note that the end portion 15 of the stator coil 2 may be pressed against the terminal portion 46 by the springback force of the stator coil 2.

  Next, arc welding for connecting the stator coil 2 and the terminal portions 46 of the conductive members 41 to 44 will be described with reference to FIG. FIG. 7A is a view for explaining arc welding for connecting the stator coil 2 used in the stator assembly 1 of the rotating electrical machine according to the first embodiment of the present invention and the terminal portions 46 of the conductive members 41 to 44. FIG. 7B is a diagram illustrating a connection shape between the end portion 15 of the stator coil 2 and the terminal portions 46 of the conductive members 41 to 44 after arc welding is performed in the state illustrated in FIG. 7A.

  As shown in FIG. 7A, the chucks 81 and 82 sandwich the end portion 15 of the stator coil 2 and the terminal portions 46 of the conductive members 41 to 44 so that the two members are brought into close contact with each other. An arc power source (not shown) is connected to the electrode 80 and the chuck 81.

  The connection between the end portion 15 of the stator coil 2 and the terminal portion 46 of the conductive members 41 to 44 is performed by discharging the inert gas from the gas nozzle 83 and connecting the terminal portions of the conductive members 41 to 44 from the electrode 80 connected to the arc power source. This is achieved by the arc flying toward 46 and melting of the terminal portions 46 of the conductive members 41 to 44 and the end portions 15 of the stator coil 2. In other words, the terminal portion 46 has a melting portion 46 a that is fixed to the end portion 15 of the stator coil 2.

  In the case of arc welding, as shown in FIG. 7B, when the conductive members 41 to 44 are melted (46a), not only the stator coil 2 and the conductive members 41 to 44 are connected but also conductive by melting. The height of the terminal part 46 of the members 41-44 becomes low, and there exists an effect that the axial direction length of stator ASSY1 becomes short. In addition to the arc welding, a resistance welding or brazing method may be used as the connection method.

If it is deeper than the width, the chuck cannot hold the stator coil 2 and the position of the stator coil 2 becomes unstable. Therefore, the recess 47 of the terminal portion 46 of the conductive members 41 to 44 needs to be shallower than the width of the stator coil 2.

Further, the end portion 15 of the stator coil 2 has the same axial position PA of the stator ASSY1 (stator core 10).

Therefore, the workability of connection is good.

  As shown in FIG. 11, when the axial heights of the stator assemblies 2 of the two end portions 15 of the stator coil 2 are made substantially the same and the heights of the terminal portions 46 of the conductive members 41 to 44 are made to be substantially the same, The height of the part that becomes.
