What characterises an FHY hysteresis electromagnetic brake?

An hysteresis FHY electromagnetic brake includes a braking torque which takes place without physical contact and therefore no wear or adjustment occur. Therefore, it has a higher life and an excellent stability.

As for the hysteresis effect, it is generated by an inductor and a hysteresis loop. The first surrounds the ring and, after applying tension, the result is magnetic poles crossing the ring and producing braking.
