摘要

A motor having a clutch device which can provide a desired one of two (or more) rotating speeds of a rotor of the motor, comprising: an armature which is rotated by a driving shaft of said rotor and is slidable along the axis thereof; two rotating drive members which are rotatably supported by said driving shaft; electromagnetic exciting members which can attract said armature to a desired one of said rotating drive members, wherein a desired one of said rotating drive members produces rotational power due to the rotation of said driving shaft via said armature.
