How Magtork™ Brakes & Clutches Operate
All Important internal clearances are ground to tolerances of less than 0.025mm (0.001 inch). Magnet assemblies (purple) surround our hysteresis assembly (gold). When like poles face each other, they produce maximum magnetic saturation of the hysteresis disc, forcing lines of flux to travel circumferentially through the hysteresis disc. This produces maximum torque.
When opposite poles face each they produce minimum saturation of the hysteresis disc. This produces minimum torque.
Combinations of adjustment angles between the two extremes give infinite adjustability. Because there are no contacting surfaces, the setting can be maintained indefinitely.
