Abstract:
1. A rotary electric machine comprising: a rotor that is rotatably supported by a housing; and a stator comprising: a stator core in which slots are formed at a ratio of two slots per phase per pole; and a first three-phase wye-delta hybrid winding and a second three-phase wye-delta hybrid winding that are mounted into said stator core, said stator being supported by said housing so as to surround said rotor, wherein: said first three-phase wye-delta hybrid winding comprises: a first delta winding that is configured by delta-connecting a delta-U a first wye winding that is constituted by a wye-U said second three-phase wye-delta hybrid winding comprises: a second delta winding that is configured by delta-connecting a delta-U a second wye winding that is constituted by a wye-U said delta-U said delta-U said delta-V said delta-V said delta-W said delta-W said delta-U said wye-U said two winding portions that are connected in parallel are respectively configured by winding said conductor wires into said slots such that inductances of said two winding portions are close, wherein a first portion of the two winding portions connected in parallel comprises a first group of conductor wires positioned radially outside on a first circumferential side of said slots, and wherein a second portion of the two wiring portions connected in parallel comprises a second group of conductor wires positioned radially outside on a second circumferential side of said slots.
