PURPOSE:To obtain the stable rotation of a rotor in the same direction by composing the pole of a stator of a section made of a soft magnetic material and a section made of a semicurable magnetic material. CONSTITUTION:A rotor 11 has a permanent magnet radially magnetized oppositely with an N-pole and an S-pole. The poles 12, 13 of a stator are formed by bonding sections 12a, 13a made of soft magnetic material such as a soft iron and sections 12b, 13b made of semicurable magnetic material. When a pulse current flowed through a coil, the poles of both the sections 12a, 13a and the sections 12b, 13b are inverted in polarity, and the rotor 11 is rotated. |
