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 stator core is prepared into a cylindrical shape by abutting four arc-shaped laminated core divisions and welding an outer surface and an inner surface of the abutted portions. Each of the laminated core divisions is prepared by bending into an arc shape a rectangular parallelepiped laminated body formed by laminating thin magnetic plates. Second outer plate-joining weld portions are applied at positions dividing the outer surface of the laminated body into three sections, and first inner and outer plate-joining weld portions are applied to the inner surface and the outer surface in the vicinity of end portions of the laminated body.
