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 for an electric rotating machine includes a stator coil that is formed of a plurality of electric wire segments each of which is comprised of an electric conductor and an insulating coat covering the electric conductor. The electric wire segments include a joined pair of first and second electric wire segments. Each of the first and second electric wire segments has an end portion of a first predetermined length where the electric conductor is not covered by the insulating coat. The end portions of the first and second electric wire segments are joined together. For each of the first and second electric wire segments, the insulating coat has, at its boundary with the end portion of the electric wire segment, a peeled portion of a second predetermined length which has a distal end peeled from the electric conductor and a proximal end remaining attached to the electric conductor.

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 alternator is disclosed having a stator, a rotor, a frame surrounding the stator and the rotor, a bowl-shaped end cover mounted on the frame and defining an electric component-part compartment, a brush unit held in sliding contact with slip rings of a rotary shaft, and a rectifier unit. The rectifier unit includes an insulating terminal block radially extending in face-to-face relation to the one end face of the frame, a positive-side cooling fin carried on one surface of the insulating terminal block, and a negative-side cooling fin carried on the other surface of the insulating terminal block. At least one of the insulating terminal block and the end cover has a heat shield plate member laterally extending through a radial space between the cooling fins and the brush unit in a direction substantially parallel to the axis of the rotary shaft.

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.
