ABSTRACT:
A rotary electric drive device for use in a vehicle anti-skid braking system has a rotary armature supported by a thrust race in relation to a housing. One part of the thrust race has external teeth for co-action with a pawl which is disengaged from the teeth for one direction of rotation of the armature but engages the teeth during rotation in the other direction to lock the race part to the housing. When this happens, slipping occurs between opposed contiguous faces of the armature and part respectively in order to dissipate some of the rotational energy of the armature when the drive device is de-energized.
