摘要： A stator includes a stator coil formed of electric wires which include a joined pair of first and second electric wires. The first electric wire has a lead portion led out from the radially inner periphery of a first slot of a stator core and including a crossover part. The crossover part crosses over an axial end face of an end part of the stator coil from the radially inside to the radially outside of the axial end face; the end part protrudes from an axial end face of the stator core. The second electric wire has a lead portion led out from the radially outer periphery of a second slot of the stator core. The lead portions of the electric wires are joined together with a joint formed therebetween. The joint is positioned closer to the axial end face of the stator core than the crossover part is.

摘要： In an AC generator for a vehicle, an end cover has two types of parts, one-type part is away from a rib part in a positive cooling fin, and the other-type part is close to the rib part. The rib part projects toward the end cover side. The one-type part is thinner than the other-type part in the end cover in order to reduce the variation of thermal expansion in each part of the end cover. This configuration increases anti-thermal fatigue of the end cover.

摘要： 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.
