ABSTRACT:
A drive unit has an electric motor having a motor shaft, an electrically disenageable arresting mechanism including a hub connectable with the motor shaft, a plurality of arresting teeth radially projecting from the hub, and at least one arresting pin for electrical disengagement of an element composed of windings of an electrically conductive wire and for disengagement of electrical current, the arresting piece being composed of a magnetically conductive material, the at least one arresting pin being arranged stationary and forming a component of a permanent-magnetic circuit relative to whose poles the arresting teeth are oriented one after the other, the electrically conductive wire being wound to form a magnetic coil which forms at least a partial length of the permanent-magnetic circuit so as to provide a temporary at least partial compensation of a permanent magnetic flux of the permanent-magnetic circuit.
