Problems solved by technology

[0003] However, in the armature (stator 10 ) for a rotating electrical machine in Patent Document 1, since the coils are pressed from both sides in the axial direction, the coils are only in contact with each other, and it is difficult to position the joint.
Therefore, there is a problem that it is difficult to properly join the first segment conductor (one-side conductor segment 28 ) and the second segment conductor (other-side conductor segments 29 , 30 ).

no. 1 approach

[0039] A first embodiment of an armature for a rotating electric machine will be described with reference to the drawings. Here, a case where an armature for a rotating electrical machine is applied to the stator 1 for an inner rotor type rotating electrical machine will be described as an example.

[0040] In addition, in this specification, a "rotating electric machine" is used as a concept including any one of a motor (electric motor), a generator (generator), and a motor / generator that functions as both a motor and a generator as needed.

[0041] 1-1. The overall structure of the stator

[0042] Below, refer to figure 1 and figure 2 The overall structure of the stator 1 of this embodiment will be described. Such as figure 1 and figure 2 As shown, the stator 1 includes a cylindrical stator core 2 and a coil 3 wound around the stator core 2 .

[0043] In addition, in the following description, unless otherwise specified, "radial direction R", "axial direction L", and...

no. 2 approach

[0066] Below, use Figure 4 A second embodiment of an armature for a rotating electric machine will be described. In this embodiment, the structure of the opposing surface 44 of the junction part 43 in the segment conductor 4 is different from the structure of the said 1st Embodiment. Hereinafter, the description will focus on differences from the first embodiment described above. In addition, it is the same as that of the said 1st Embodiment about the point which is not demonstrated especially.

[0067] Such as Figure 4 As shown, in this embodiment, the opposing surface 44 is formed over the entire axial end surface of the front end portion of the conductor edge portion 41, and includes a first inclined surface 441, a second inclined surface 442, and a third inclined surface. 443. Further, a first inclined surface 441 , a second inclined surface 442 , and a third inclined surface 443 are arranged in this order from the front end toward the proximal end in the axial direc...

no. 3 approach

[0090] Below, use Figure 8 A third embodiment of an armature for a rotating electrical machine will be described. In this embodiment, the structure of the opposing surface 44 of the junction part 43 in the segment conductor 4 differs from the structure of the said 1st Embodiment and the said 2nd Embodiment. Hereinafter, the description will focus on differences from the above-mentioned first embodiment and the above-mentioned second embodiment. In addition, it is the same as that of the said 1st Embodiment and the said 2nd Embodiment about the point which is not demonstrated especially.

[0091] Such as Figure 8 As shown, in the present embodiment, the facing surface 44 is a flat surface formed over the entire axial end surface of the front end portion of the conductor side portion 41 and extending along the radial direction R. As shown in FIG. In this embodiment, the facing surface 44 is arranged parallel to the circumferential direction C. As shown in FIG. In addition,...

Abstract

In the present invention, a manufacturing step (S1) for a stator (1) comprises: an arrangement step (S12) in which at least one of a conductor edge part (41) of a first segment conductor (5) and a conductor edge part (41) of a second segment conductor (6) is arranged within a slot (21) so that an opposing face (44) of one joint part (43) of the first segment conductor (5) and an opposing face (44)of one joint part (43) of the second segment conductor (6) oppose each other; a restriction step (S15) in which movement in the radial direction (R) of the conductor edge parts (41) is restricted; and a joining step (S14) in which at least one of the first segment conductor (5) and the second segment conductor (6) is pressed in the axial direction (L) so that the first segment conductor (5) and second segment conductor (6) approach each other while maintaining the restriction state of the restriction step (S15), and the joint part (43) of the first segment conductor (5) and the joint part (43) of the second segment conductor (6) are joined.

Description

technical field [0001] The present invention relates to a method of manufacturing an armature for a rotating electric machine including a cylindrical armature core in which a plurality of axially extending grooves are disposed in the circumferential direction, and a coil wound around the armature core. Background technique [0002] There is known a technique in which a coil of an armature for a rotating electric machine is formed by joining a plurality of segment conductors. For example, Patent Document 1 below discloses a first segment conductor (one-side conductor segment 28 ) arranged on one axial side of the armature core (stator core 14 ), and a An armature (stator 10 ) for a rotating electric machine with coils formed by joining second segment conductors (other side conductor segments 29 and 30 ) on the other axial side of the armature core (stator core 14 ). In the armature (stator 10) for a rotating electrical machine of Patent Document 1, a convex portion is formed...
