Spring applied power off brake Fail-safe, spring applied power off brakes for use in demanding applications. Designed with power-off brake engagement, engaging when electrical power supply is removed. Key features Fail-safe Power off brake engagement/electrically released High braking torque High operating speeds (dependent on size) Precision holding Low moment of inertia Horizontal and vertical mounting Toothed hub/friction disc connection Water resistant versions available Optional voltages Product description The electromagnetic spring applied power off brake (sometimes known as a safety brake or fail-safe brake) is designed so that when the electrical power supply is removed, the brake engages (power-off brake engagement). The spring applied brake can be designed to be used as a holding brake (parking), or dynamically where an emergency stop functionality is required (E-stop). Our spring applied power off brakes are robust and reliable, generally incorporating multiple internal compression springs. The multiple springs provide an added safety feature, ensuring that the brake would still function should one spring fail prematurely. When power is cut the coil’s magnetic field decays, the springs force an axially moving armature plate forwards to engage and lock the rotating friction disc. The electromagnetic spring applied brake is ideal for integration into servomotors and can be mounted externally or integrated into the motor housing.
