Magnetic powder clutch is a kind of multi-purpose

Magnetic powder clutch is a kind of superior performance of the multi-purpose automatic control element, is based on the electromagnetic principle and the use of magnetic powder transfer torque, in the case of has nothing to do with the slip can transfer torque, with fast response speed, simple structure, no pollution, no noise, no impact vibration energy saving, etc. Has been widely used in papermaking, printing, plastics, rubber, textile, printing and dyeing, wire and cable, metallurgy and other relevant rolling and coiling processing industry of winding tension control. 

Magnetic powder clutch can also be used to buffer starting, overload protection, speed, etc., as long as you change the size of exciting current, can easily control the size of torque. When the excitation current is kept constant, the convey of the torque is not affected by the impact of transmission parts between the follower and differential, namely static moment and torque. So can steadily convey constant torque. If this feature is applied to tension control, the users only need to adjust the size of exciting current, can accurate control and communicate the required torque, which is simple and effective to achieve the objective of the coiling tension control. 

The choice of the magnetic powder clutch and location: on the premise of the slip power matching, put the magnetic powder clutch in high level, you can choose small specifications of the clutch, the volume, the cost is also reduced. When small magnetic powder clutch can not match, but need larger magnetic powder clutch, should be in a middle or at the back of the drive mechanism, to increase work torque reduce slip speed.
