MINEX®-H Hysteresis coupling

up to 10 Nm / Hysteresis coupling

Having reached the maximum torque, the MINEX-H hysteresis coupling switches to slipping operation, thus ensuring wear-free torque limitation.

As long as the operating torque is less than the selected torque (slipping torque), the speed is transmitted synchronously. As soon as the operating torque exceeds the selected torque, the coupling 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 torque with overload remains almost constant but might lightly rise with an increasing relative speed and the resulting losses of eddy current.


  • maintenance-free hysteresis coupling by contactless torque transmission by means of magnetic forces

  • wear-free torque limitation

  • load-holding

  • very good repeatability of torque

  • maintenance-free
