A family of electrically released brakes are designed to automatically engage when power to them is disconnected.
The ERS spring set brakes use a system of springs and a magnetic coil to generate braking torque. This style is normally limited to use in static holding applications with only occasional emergency stop cycling. Five models handle torque ratings from 1.5 lb-ft to 100 lb-ft.
The FB/ER series permanent magnet style brakes use both a permanent magnet and magnetic coil to generate torque and control the brake. The magnetic coils counter permanent magnetic force to hold brake "off" when current is applied. All FB/ER brakes are designed for dynamic engagement applications which cycle brakes periodically. FB models, which include bearing mounting hubs, are available in three sizes and handle torque ratings from 10.5 lb-ft to 56 lb-ft. Seven ER models, which require assembly on the shaft, handle torque ratings of 10.5 lb-ft to 400 lb-ft.
