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 sequentially arranged from the front end toward the proximal end in the axial direct...
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,...
