摘要： A rotating electrical machine has a housing, a stator having a stator core and a rotor having a rotor core and rotor side plates rotatably supported by the housing. The rotor core is arranged to have a gap between the end surfaces of the rotor core and the stator. Oil containers are arranged on at least one surface of the rotor side plate. Each oil container has a scoop-up part and an exhaust outlet formed on end sections thereof. When the rotor is rotating, the scoop-up part scoops up an oil stored in the housing, the oil and inside air are compressed in the oil container, and the exhaust outlet exhausts the oil and compressed air to the coil end of the stator. The housing stores the oil at a lowermost side thereof so that the scoop-up part and the exhaust outlet are immersed in the oil.

摘要： A rotary electric machine includes a stator. The stator has a coil end provided by a plurality of joint portions. The coil end has a leader wire connected to a power terminal. The stator has a coil end provided by a plurality of turn portions. The coil end has a circumferential pair whose top portions are offset in a circumferential direction. The circumferential pair has a height HG21. The coil end has an axial pair whose top portions are offset in an axial direction. The axial pair has a height HG22. The housing has a facing surface facing the coil end. The coil end provides a height distribution which adapts an unevenness of the opposing surface.

摘要： An electric rotary machine includes a stator, which Is fixed to a housing, composed of a stator core having a coil end protruding at an end face of the stator core, a rotor core formed by laminating core sheets, and a rotor having a pair of rotor side-plates sandwiching both end faces of the rotor core. The rotor core is rotatably supported in the housing facing an inner peripheral surface of the stator with a gap between the rotor core and the stator. Either one or both of the rotor side-plates has a concave surface in an outer surface of the side-plate that does not abut the rotor core. An axial distance from the end face of the rotor core to the concave surface increases from an inner diameter side to an outer diameter side.

摘要： An armature for a rotating electric machine includes an armature core and an armature coil. The armature core includes a substantially annular main body disposed in radial opposition to a field of the machine and teeth extending from the main body radially toward the field. The armature coil is arranged between the teeth of the armature core. For each of the teeth, there are formed a protrusion and a pair of claws at a distal end of the tooth. The protrusion protrudes from a circumferentially central part of the distal end of the tooth radially toward the field. The claws extend, respectively on opposite circumferential sides of the protrusion, from the distal end of the tooth toward the field. Each of the claws has a smaller width at its distal end than at its proximal end and is arcuate-shaped so as to engage with and thereby retain the armature coil.

摘要： A double-stator electric rotating machine with a retainer. The retainer includes a connector which joints between an outer stator and an inner stator. The retainer is placed in contact with an outer peripheral surface of the outer stator and an inner peripheral surface of the inner stator to retain the outer and inner stators together. Specifically, the retainer works to join the outer stator and the inner stator together and also to tightly hold the outer periphery of the outer stator and the inner periphery of the inner stator, thus minimizing misalignment of the outer and inner stators in axial and radial directions there of.
