ABSTRACT:
An electromagnetic motorbrake has three wear compensating studs with threaded portions that receive nuts. The threaded nuts define cylindrical wrap surfaces for spring clutch elements that are coupled between the armature and the pressure plate of the brake by a bellcrank to be sequentially wrapped to turn the nuts as required to automatically take up any excessive gap between the armature and the electromagnet due to wear of the friction disc between the armature and the pressure plate.
