摘要:
An armature for a rotary electric machine includes: a core that includes a plurality of teeth that are arranged at a predetermined pitch in a circumferential direction; and a plurality of edgewise coils that are configured by winding a rectangular conductor wire into an edgewise winding, the plurality of edgewise coils each include rectilinear portions and coil end portions that are arranged radially, and that are each linked by bent portions, the rectilinear portions are arranged radially on circumferential side portions of the teeth so as to be gradually further away from a central axis of the teeth from a tip end of the teeth toward a root, and radially adjacent portions of the rectangular conductor wire are configured such that bulging portions that arise due to compressive stresses resulting from bending at inner peripheral side portions of the bent portions do not face each other.
