Problems solved by technology

[0003] However, in the armature (stator 10 ) for a rotating electrical machine in Patent Document 1, since it is pressed from both sides in the axial direction, the coils only contact 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 the armature for a rotating electrical machine will be described with reference to the drawings. Here, a case where the 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, "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 configuration of the stator 1 of the present embodiment will be described. like 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 stated, "radial direction R", "axial direction ...

no. 2 approach

[0066] Below, use Figure 4 A second embodiment of the armature for a rotating electrical machine will be described. In the present embodiment, the structure of the opposing surface 44 of the joint portion 43 in the segment conductor 4 is different from the structure of the above-described first embodiment. Hereinafter, the difference from the above-described first embodiment will be mainly described. In addition, it is the same as the above-mentioned 1st Embodiment about the point which is not demonstrated in particular.

[0067] like Figure 4 As shown, in the present embodiment, the opposing surface 44 is formed over the entire axial end surface in the front end portion of the conductor side portion 41, and includes a first inclined surface 441, a second inclined surface 442, and a third inclined surface 443. Furthermore, the first inclined surface 441 , the second inclined surface 442 , and the third inclined surface 443 are arranged in this order from the front end po...

no. 3 approach

[0090] Below, use Figure 8 A third embodiment of the armature for a rotating electrical machine will be described. In the present embodiment, the structure of the opposing surface 44 of the joint portion 43 in the segment conductor 4 is different from the structures of the above-described first embodiment and the above-described second embodiment. Hereinafter, the difference from the above-described first embodiment and the above-described second embodiment will be mainly described. 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 in particular.

[0091] like Figure 8 As shown, in the present embodiment, the opposing surface 44 is a flat surface that is formed over the entire axial end surface of the front end portion of the conductor side portion 41 and extends along the radial direction R. As shown in FIG. In this embodiment, the opposing surface 44 is arranged in parallel with the circu...

Abstract

The manufacturing process (S1) of the stator (1) includes: a preparation process (S10) of preparing a plurality of segment conductors (4) and preparing a stator core (2), wherein the segment conductors (4) have conductor sides ( 41), the conductor edge (41) is provided with a junction (43) having an opposite surface (44); In the manner opposite to the opposite surface (44) of a joint (43) in the second segment conductor (6), the conductor edge (41) of the first segment conductor (5) and the second segment An arrangement step (S12) of disposing at least one of the conductor side portions (41) of the conductor (6) in the groove (21); a restriction step (S15) of restricting the movement of the conductor side portion (41) in the radial direction (R); And the joining step (S14) of joining the joint portion (43) of the first segment conductor (5) and the joint portion (43) of the second segment conductor (6) while maintaining the restrained state in the restraint process (S15). ).

Description

technical field [0001] The present invention relates to a method for manufacturing an armature for a rotating electrical machine including a cylindrical armature core body having a plurality of axially extending grooves arranged in the circumferential direction, and a coil wound around the armature core body. Background technique [0002] There is known a technique for forming a coil of an armature for a rotating electric machine 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 side in the axial direction of an armature core (stator core 14 ), and a first segment conductor (one-side conductor segment 28 ) arranged on The armature (stator 10 ) for a rotating electric machine is a coil formed by joining the second segment conductors (the other conductor segments 29 and 30 ) on the other side in the axial direction of the armature core (stator core 14 ). In th...
