    • A permanent magnet motor includes a P-pole-implanted permanent magnet rotator containing a ferrite magnet in a laminated silicon steel sheet, wherein, at one pole, a U-shaped permanent magnet comprising three parts, and, at the outer periphery of the U-shaped magnet, one outer-periphery permanent magnet disposed longitudinally in the peripheral direction are provided to generate permanent magnet torque. At one pole, the permanent magnet rotator generates reluctance torque using two salient poles formed between the U-shaped permanent magnet and the outer-periphery permanent magnet. One central salient pole is formed between the adjacent poles. A stator comprises an M-phase stator winding that is a distributed winding, and a stator core having Ns slots. The ratio of Ns/P/M is a common fraction. When the width of the center salient pole is set to τcp and the slot pitch of the stator core is set to τs, τcp is smaller than τs.
