MINEX®H hysteresis couplings

The  MINEX-H hysteresis 联轴器 transmits the 扭矩 from the driving to the driven element without contact via magnetic forces (wear-free 扭矩 transmission). Operation of the hysteresis 联轴器: Having reached the maximum 扭矩, the  MINEX-H hysteresis 联轴器 switches to slipping operation, thus ensuring wear-free 扭矩 limitation. As long as the operating 扭矩 is lower than the selected 扭矩 (slipping 扭矩), the speed is transmitted synchronously. As soon as the operating 扭矩 exceeds the selected 扭矩, the 联轴器 slips  and there is a relative speed between driving and driven side.  At this moment the polarity of the hysteresis material is continuously reversed and it heats up. The holding 扭矩 with overload remains almost constant, but might lightly rise with an increasing relative speed and the resulting losses of eddy current.
