Magnetic Brakes
Magnetic brakes use permanent magnets to produce a braking force on a moving conductor. A high level of braking force can be achieved with no moving parts and no external power supplies. The permanent magnet eddy current brake is an extremely flexible device which can give the user the following substantial benefits:
- Compact size
- Efficient
- Very simple to use
- Require almost no maintenance
- Fail safe
The standard magnetic brake unit consists of high strength rare earth magnets fixed to a mild steel plate. The magnets are protected against corrosion and a stainless steel cover fitted to provide mechanical protection.
