Abstract
The brake assembly includes a motor shaft connected to a friction disk assembly. Springs housed in a field cup assembly, frictionally link a clapper plate assembly and friction disk assembly against a mounting plate to activate the brake. To disengage the brake, the field cup assembly magnetically attracts the clapper plate thereto and the friction disk assembly is free to rotate. For manual release, rotation of a lever arm against a reaction plate compresses a wave spring to generate an opposing force which overcomes the springs, thereby forcing the clapper plate assembly away from the friction disk assembly to allow rotation thereof.
