A dynamoelectric machine includes: a rotor that has 2 n field poles, where n is a positive integer; and a stator including: a stator core in which 2 n×6 slots that are partitioned by adjacent teeth are formed at a predetermined pitch circumferentially; and first and second three-phase alternating-current windings that are each configured by delta-connecting three phase windings that are mounted to the stator core such that an electrical angle phase difference therebetween is 120 degrees, each of the phase windings being configured by connecting in series pairs of coil winding portions that are mounted to the stator core so as to have different electrical angular phases from each other, and an electrical angle phase difference between the first and second three-phase alternating-current windings is 30 degrees.
