PURPOSE:To reduce the number of parts and to shorten the axial length by interposing a middle plate between two coils for forming a stator, and extending pole teeth integrally form the plate. CONSTITUTION:Two coils 6, 7 are disposed on the same shaft, and a middle plate 8 is interposed therebetween. Pole teeth 19, 20 extending at the inner peripheral side of coils 6, 7 are integrally formed with the plate 8. Yokes 2, 3 having pole teeth 14, 15 disposed between the poles 19 and 20 of the plate 8 are mounted on the coils 6, 7 to form a stator 1. A rotor 10 having a permanent magnet 11 is supported on the central shaft of the stator 1, and a set of rotor poles of the teeth 6, 19 of the first coil 6 side and a set of rotor poles of the poles 15, and the teeth 20 of the second coil 7 side are displaced at the prescribed electric angle. |
