Operation
Friction discs rotate with the motor shaft and are free to move axially on the hub. When the magnet coil is de-energized, a spring loaded pressure plate (magnet armature) presses against the rotating discs. Friction force stops and holds the motor shaft. The pressure plate retracts against torque springs by magnetic force when the magnet is energized. Friction discs are then released and free to rotate with the hub and motor shaft. A manual release is also provided. Brake coil leads connect directly to motor leads so that power is simultaneously supplied to both brake and motor. No control equipment is required. An instruction bulletin on mounting and hookup are included with each brake.
Splined Hub
These C-Face brakes use splined hubs and internally splined friction discs as standard equipment. The spline design virtually elimi nates back lash which is a delayed action effect caused by excessive clearances between hub and discs. Splines in crease disc life because the many con tact points between hub and discs reduce the concentration of stresses encountered with non-splined hubs having only a few contact points.
