summary
Hysteresis clutch according to the principle of hysteresis, hysteresis torque transmitted, excitation current and torque linearly. In the case of non slip, can transmit a certain torque, has the advantages of fast response, simple structure, no pollution, no noise, no impact vibration energy saving and so on. Is a versatile, superior performance of automatic control components. It can be widely used in the field of tension control of the winding of the buffer, the overload protection, the speed regulation and the winding system.
