The first rotor 14 has first pole teeth 36, and second pole teeth 38, that are provided alternately along a circumferential direction. The first pole teeth 36 serve as first magnetic poles of the rotating magnetic field, and the second pole teeth 38 serve as second magnetic poles of the same. The second rotor 16 has a plurality of permanent magnets 30 arranged along the circumferential direction. The first rotor 14 also has a first pole teeth ring 40 and a second pole teeth ring 42. In the first pole teeth ring 40, the first pole teeth 36 are provided at intervals in the circumferential direction. In the second pole teeth ring 42, the second pole teeth 38 are provided at intervals in the circumferential direction. The second pole teeth ring 42 is arranged opposite the first pole teeth ring 40 in such a manner that the second pole teeth 38 are arranged in respective gaps between adjacent pairs of the first pole teeth 36.
