Abstract:
The present invention provides a vibration-generating stepping motor including: two stator yokes; a bearing that magnetically couples the two stator yokes; a rotor frame that rotates on a circumference of the stator yokes; and an eccentric weight that shifts a gravity center of the rotor frame from a rotation center of the rotor frame.
