An injection molded friction disc is provided, as well as a keyed hubless design. A manual release mechanism is also provided. An energization coil is provided enabling simplified connection lead bonding. A spring set brake includes a magnetically permeable body having a pole face. An armature is axially movable toward and away from the pole face. An energization coil is energizable to magnetically attract the armature toward the pole face. A biasing member biases the armature away from the pole face. A pressure plate is spaced from the pole face by a plurality of legs. A friction disc between the armature and the pressure plate is keyable to an axially extending rotary shaft, such as a motor shaft. Upon de-energization of the coil, the biasing member biases the armature to a braking position pushing the friction disc against the pressure plate to stop rotation of the friction disc and the shaft. The armature in the braking position defines an air gap between the pole face and the armature. Upon energization of the coil, the armature is pulled toward the pole face to a released position releasing the friction disc and permitting rotation of the shaft. The noted air gap is adjusted by machining the ends of the legs on one or the other of the pole face and pressure plate. This is time consuming and costly, particularly in precision applications because the magnetic air gap must be controlled within close tolerances to enable proper magnetic attractive force. These precision machining operations are undesirable from a manufacturing cost standpoint. The present invention addresses and solves the noted problem and eliminates the objectionable high cost machining manufacturing steps. The invention provides a simple, cost effective structure and method for setting the magnetic air gap.
