ABSTRACT:
A vehicle rotary electric machine includes a rotor, a stator having a stator core and a stator winding mounted in the stator core and a pair of frames for supporting the rotor and the stator. The stator winding has a plurality of conductor segments coated with insulation film. Each of the conductor segments has segment ends that are circumferentially aligned and form tow or more rings. The segment ends that contact each other are welded and form joints of winding that have a bare surface. Therefore, electrolyte or foreign particles are prevented from staying at otherwise deteriorated insulation film.
