Slots are formed at a nonuniform pitch at a ratio of two slots per phase per pole. An X-phase winding phase portion constituting a stator winding is constructed by connecting in series an a phase winding phase sub-portion and a d-phase winding phase sub-portion having a phase difference corresponding to an electrical angle of 34 degrees, a Y-phase winding phase portion is constructed by connecting in series a b-phase winding phase sub-portion and an e-phase winding phase sub-portion having a phase difference corresponding to an electrical angle of 34 degrees, and a Z-phase winding phase portion is constructed by connecting in series a c-phase winding phase sub-portion and an f-phase winding phase sub-portion having a phase difference corresponding to an electrical angle of 34 degrees. <IMAGE>
