Abstract

PURPOSE:To enable the self-excitation of a synchronous motor and to shorten the axial length of the motor by mounting a permanent magnet to a rotor, forming a stator of a frame structure, and forming the poles of the stator of the prescribed shape. CONSTITUTION:Permanent magnets 10 are so mounted as to become alternately different polarity at the respective sides of a rotor 1 made of soft iron material of regularly polygonal shape, and a stator 2 of frame shape is provided on the outer periphery of the rotor 1. Magnetic poles 20 are provided at the positions faced with the rotor 1 of the frame 23 of the stator 2, extending surface 21 having the prescribed gradient is formed at least a pair of facing poles 20a of the poles 20, and a slit 22 is formed at the position corresponding to the pole 20 on the frame 23. In this manner, since the poles 20a simultaneously attract and repel a pair of adjacent permanent magnets 10 at the starting time, self-excitation is enabled.
