ABSTRACT:
A motor including an electromagnetically actuated friction clutch and friction brake for respectively transferring a driving torque and/or a braking torque to an output shaft. A rigid hub is rotationally fixed on an output shaft of the motor for rotation therewith. A first axially deflectable spring washer is connected to an annular shaped clutch disk, with a second axially deflectable spring washer being connected to a brake disk. The clutch disk and brake disk are axially movable by a magnetic force and are adapted to be pressed against a driving pulley and a braking block respectively. The hub is fashioned as a one piece member and a supporting ring is disposed axially between the clutch disk and the brake disk. The axially deflectable spring washers are prestressed in a rest position and, at points that are essentially the same radial distance from the axis of the hub but staggered with respect to one another in the direction of rotation of the motor, are connected with the supporting ring and the clutch disk or brake disk. The output shaft is adjustable in an axial direction for the purposes of enabling an adjustment of a brake slack and/or a play in the clutch.
