Electric Motor Brakes

Electric Motor Brakes Multiple Disc Spring Set Electric Brakes (EFS)
EFS Electric Motor Brake
Carlyle Johnson's MAXITORQ® Multiple Disc Spring Set Brakes and electric motor brakes are suited for applications demanding fast, positive braking to stop machines.
These electric motor brakes are designed and built to provide unusually high torque for their compact size, and meet the braking requirements of a wide range of machinery.
The design of CJM's EFS Electric Brakes (and electric motor brakes) incorporates a MAXITORQ® multiple disc brake unit, which is kept compressed by radially-spaced coil springs between the armature and end plate, resulting in a constant "holding" force as long as the coil is not energized.
When energized, electromagnetic force flows through the flux path to override spring pressure, releasing the friction discs for drag-free shaft rotation.
Carlyle Johnson engineering staff can modify our standard electric brakes electric motor brakes, or we can develop a new product to meet your exact specific needs.
Features of EFS Electric Brakes Electric Motor Brakes
Furnished ready for use, Carlyle Johnson's EFS electric spring set electric brakes electric motor brakes can be quickly installed by sliding the brake over the keyed shaft and bolting it to a frame member. Optional C-faced non-magnetic flanges are available which enable direct-mounting on C-frame motors.
EFS Fail-Safe brakes can also function as a torque-limiting device.
