Abstract
A stator has a stator core provided with slots formed at a ratio of two per phase per pole and a stator winding composed of an a-phase, a d-phase, a c-phase, an f-phase, a b-phase, and an e-phase winding phase portions mounted to the stator core, wherein a′-phase winding phase portion is constructed by connecting the a-phase winding phase portion and the d-phase winding phase portion in series by a first interphase crossover portion, a b′-phase winding phase portion is constructed by connecting the b-phase winding phase portion and the e-phase winding phase portion in series by a second interphase crossover portion, and a c′-phase winding phase portion is constructed by connecting the c-phase winding phase portion and the f-phase winding phase portion in series by a third interphase crossover portion, the interphase crossover portions being arranged so as to be offset in a circumferential direction.
