PURPOSE:To increase the output of a motor by using a strong magnet material by using both sides of a disc-shaped magnet rotor. CONSTITUTION:Pole teeth of a stator 4 are alternately excited to S-pole and N- pole by energizing a stator winding 45. A rotor 1 is stopped by the generation of the S-pole and N-pole so that the poles N1, N2, N3, ... of the rotor 1 are opposed to the S-pole of the stator 4 and the poles S1, S2, S3,... of the rotor 1 are opposed to the N-pole of the stator 4. Then, the energization of the stator winding 45 is interrupted, a current is flowed to the stator winding 45', and the poles of the stator 4' are alternately excited to S-poles and N-poles. The rotor 1 is moved to the position that the poles N1, N2, N3,... of the rotor 1 are opposed to the S-pole of the stator 4' and the poles S1, S2, S3,... of the rotor 1 are opposed to the N-pole of the stator 4', and stopped. |
