    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： An electrically-insulating resin portion is formed by applying a resin so as to cover apex portions of coil ends forming a coil end group, that is, weld portions and surfaces of portions where an insulation coating has been removed from free ends of coil segments which constitute joint portions between the free ends. Spaces between radially-adjacent joint portions may be filled by the electrically-insulating resin portion. In addition, air passage spaces may be ensured between circumferentially-adjacent joint portions.
