ABSTRACT:
A hybrid-type stepping motor has coils on stator yokes mounted on a fixed shaft or coils wound on the inner circumferences of stator yokes. This hybrid-type stepping motor is easy to coil wind, offers a substantially high density of coils, and achieves a reduction in cost. The use of sub flat magnets and sub magnetic plates on both sides of a stator yoke body allows magnetic circuits to form on both sides of the stator yoke body. This arrangement results in an increase in torque. Additionally, multiple-phase motor is easily constructed.
