STEPPING MOTOR FOR GENERATING VIBRATION

摘要

A stepping motor for generating vibration in which the stopping position can be securely held by increasing a detent torque. The pole teeth of one stator yoke of a set of one-phase stator yokes are formed in two types of pole teeth with different outermost face areas in the radial direction and the pole teeth of the other are formed in two types of pole teeth with different outermost face areas in the radial direction. One type of pole teeth of these stator yokes are formed in the same shape and the remaining two types of pole teeth which are not formed in the same shape are combined with each other and disposed so that the detent torque can be increased.
