Like the Hysteresis Brake, the Magtrol Hysteresis Clutch develops torque strictly through a magnetic air-gap, ensuring an absolutely smooth transmission of torque from the drive unit to the driven element. Designed to be powered without the use of brushes or slip rings, and being a pure hysteresis device, there is never any fear of contamination due to wear particles or leaky seals. This makes Magtrol Hysteresis Clutches and Brakes ideal for use in food processing and clean room environments.

For every application determine the TORQUE, MAXIMUM RPM, and for brakes, the BENDING MOMENT.
Then you can choose the correct shaft or coupling, and various accessories.
All important internal clearances are ground to tolerances of less than .025mm (.001 in). Magnet Assemblies (purple) surround our hysteresis disc (gold). When like poles face each other, they produce maximum magnetic saturation, forcing lines of flux to travel circumferentially through the hysteresis disc. This produces Maximum torque.
When opposite poles face each other, they produce minimum saturation of the hysteresis disc. The lines of flux travel right through the hysteresis disc. Combinations of adjustment angles between these two extremes gives infinite adjustability. Because there are no contacting surfaces, the setting can be maintained indefinitely.
