Abstract

PURPOSE: To select a direction of rotation optionally and reduce vibration, by preparing two stator coils, deviating the magnetic centers of the coils at a very small distance from both sides of the centers of stator poles and using one stator coil for diving and the other for braking.
CONSTITUTION: A first stator 21 fitted with a stator coil 41 and a second stator 22 fitted with a stator coil 42 are provided. The magnetic center lines l1, l2 are deviated at a very small angle θ/2 to both the sides of the center lines of magnetic poles. The stator coils 41, 42 are so wired that one of the coils is short-circuited when the other is connected to a power source. The stator coils can be switched by each other through a switch 7. As a result, one of the stator coils serves for braking while the other is selected for driving, and the direction of rotation can be changed optionally, a normal stepping range is widened and generation of vibration is reduced.
