ABSTRACT:
The phase difference between the pole teeth of a first stator and the pole teeth of a second stator is set to 30-80 degrees or 100-150 degrees in electrical angle, whereby the magnitude of combined torque of the torque generated by the pole teeth of the first stator and the torque generated by the pole teeth of the second stator becomes larger when the step number is odd and becomes smaller when the step number is even. Accordingly, when the number of steps for one motion is an even number at all times, the starting torque can be increased and the settling torque can be decreased.
