ABSTRACT:
A mechanism for transferring torque from a motor to a gear train through a magnetic hysteresis slip clutch has a feature for disconnecting the motor from the gear train. A cup element of the clutch is carried on a shaft and can be shifted along the shaft's axis. The cup element has a magnetic member on its outer surface and an interior hysteresis layer. An electromagnet can magnetically apply force to the magnetic member to axially shift the cup element, and by so doing can shift a drive gear carried on the cup element into and out of mesh with a first gear of the gear train. In a preferred embodiment, the cup element shifts the drive gear into mesh with the gear train's first gear when the electromagnet is energized and magnetically applies force to the magnetic member, and allows magnetic force applied to the hysteresis layer by a permanent magnet element of the clutch to shift the drive gear into its unmeshed position when the electromagnet is deenergized and does not apply force to the magnetic member.
