摘要： An alternator includes a stator and a rotor disposed inside the stator and rotated by an engine of an automobile. The stator is composed of a cylindrical stator core and a stator winding held in the stator core. The stator winding extends from an axial end of the stator core, forming a circular coil end along an axial circumference of the stator core. Lead wires led out from phase-windings in the stator winding are held on and along the circular coil end and bonded thereto with adhesive. A depressed ditch is formed on the coil end, and the lead wires are disposed in the depressed ditch and firmly held therein to prevent movement of the lead wires relative to the coil end.

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.

摘要： An AC generator has negative pole-side rectifier devices press-fitted to a holder fin so as to dispose a bottom face of the rectifier device on a surface of the holder fin. The holder fin is disposed in such a manner that the bottom face of the rectifier device faces a rear frame of the AC generator. A clearance is formed between the rear frame and the bottom face through which the cooling wind for the rectifier device flows. The rear frame is provided with a slant face on its outer wall face for inducing the cooling wind introduced through an opening of the protection cover of the AC generator to the rectifier devices. Thus, the cooling wind induced by the slant face can hit on the bottom face of the rectifier devices directly, so as to cool the rectifier device well.
