摘要： Slots are formed in a stator core at a ratio of two per phase per pole and winding phase portions constituted by star-shaped winding units are installed in the stator core so as to line up in six layers radially. An a-phase winding phase portion, a b-phase winding phase portion, and a c-phase winding phase portion constituting a first three-phase alternating-current winding constitute three radially-outer layers, and a d-phase winding phase portion, an e-phase winding phase portion, and an f-phase winding phase portion constituting a second three-phase alternating-current winding constitute three radially-inner layers.

摘要： Six single phase winding portions are installed in slots disposed at a ratio of two per phase per pole. Each single-phase winding portion has two wave windings formed by winding a conductor wire for a predetermined number of winds into a wave-shaped pattern composed of slot-housed portions disposed at a pitch of six slots in a circumferential direction and crossover portions linking together end portions of adjacent pairs of the slot-housed portions alternately relative to an axial direction, the wave windings being offset by six slots from each other circumferentially and installed in the slots such that the crossover portions face each other axially.

摘要： A rotor structure comprising magnets for suppressing the leakage of a magnetic flux between the side faces of the adjacent claw-like magnetic poles and metal holding members each of which covers the magnets together with the claw-like magnetic pole and radiates heat transmitted to the claw-like magnetic pole at the time of power generation. Therefore, the quantity of heat radiated to the peripheral portions of the magnets is increased and the coolability of the magnets can be greatly improved.
