ABSTRACT:
A mechanical disconnect assembly is disclosed for rapid disengagement of an electric motor from a gear or shaft system on loss of power to the motor, and for rapid reengagement of the motor upon restoration of electric power thereto. The assembly utilizes a sliding slave member made of a magnetic material and arranged to be drawn into the magnetic field of the electric motor when under power. The slave member is operably connected to a sliding engagement member on the motor output shaft and is resiliently biased out of said magnetic field by spring means and out of engagement with the gear assembly.
