Patent ID: 8519591

Claim:
A dynamoelectric machine comprising: a rotor that has 2n field poles, where n is a positive integer; a stator comprising: a stator core in which 2n×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 said stator core such that an electrical angle phase difference therebetween is 120 degrees; and a rectifier that rectifies alternating-current output that is induced in said first and second three-phase alternating-current windings due to rotation of said rotor, wherein: each of said phase windings is configured by connecting in series pairs of coil winding portions that are mounted to said stator core so as to have different electrical angular phases from each other; and an electrical angle phase difference between said first and second three-phase alternating-current windings is 30 degrees.
