Abstract
A stator winding is configured by connecting a first three-phase stator winding and a second three-phase stator winding in parallel. A U-phase winding of the first three-phase stator winding is configured by connecting a U-phase winding portion and a U-phase winding portion in series, and a U-phase winding of the second three-phase stator winding is configured by connecting a U-phase winding portion and a U-phase winding portion in series. The U-phase winding portion and the U-phase winding portion are m-turn wave windings, and the U-phase winding portion and the U-phase winding portion are n-turn wave windings (where n does not equal m). The U-phase winding portion and the U-phase winding portion are mounted into a first slot group, and the U-phase winding portion and the U-phase winding portion are mounted into a second slot group.
