Coil for rotary electric machine

Abstract:

A coil for a rotary electric machine is mounted in a plurality of slots of a stator core having the slots in a circumferential direction. An overlapping coil-type wave winding coil constituted by a coil wire having a plurality of slot accommodating portions accommodated in the slots and a plurality of coil end portions interconnecting, in a chevron shape, the slot accommodating portions next to each other outside the slots in an axial direction of the stator core constitutes the coil. At least two layers of the coil wire are connected by a continuous wire-based connecting portion, folded back in the connecting portion, and stacked.
