Rotating shaft brakes provide the ability to stop a rotating shaft on a space craft, launch vehicle, aircraft, land-based vehicle or commercial and industrial equipment. The FSB-series electrically off brake is designed to stop a rotating shaft in milliseconds after power interruption. The brake is held off electrically, a field coil creating the magnetic holding force. When power is shut off or interrupted, a spring set causes the brake to activate, stopping the shaft rotation. Failsafe brakes are often mounted on the end of a motor shaft but can be mounted on the end of any rotating shaft in the drive train.
Failsafe Spring Set Brake applications include:
