Abstract:
An electric motor comprising:a housing; a stator supported by said housing; a shaft supported by said housing for rotation about an axis; a rotor supported by said shaft for rotation therewith relative to said stator; a switch supported by said housing, said switch including a pair of flexible, elongated arms; a switch actuator button which is not fixed to either arm; and a centrifugal governor mounted on said shaft for rotation therewith, such that as said shaft rotates, said governor causes said actuator button to force said arms together to close said switch until such time as said shaft reaches a predetermined rotational speed, after which, centrifugal forces generated by said shaft and acting upon said governor cause said governor to allow said actuator button to move in a direction that allows said arms to separate, thereby opening said switch.
