ABSTRACT:
A device which brakes a drive motor having a rotor adapted to be axially displaced when the motor winding is de-energized. A braking member moves with the rotor so that when the motor winding is deenergized, the circumferential surface of the braking member engages the stationary member to frictionally stop the rotation of the rotor. When the braking member engages the stationary member, the exterior circumferential surface thereof pivots to position substantially the entire surface of the exterior circumferential surface in contact with the stationary member. Energization of the motor moves the braking member with the rotor away from the stationary member and the exterior surface of the braking member pivots to disengage from the stationary member enabling the rotor to rotate.
