What is a magnetic powder clutch?

A magnetic powder clutch is an electromagnetic torque transmission device that uses magnetic powder to transfer adjustable torque between input and output shafts.

What industries use magnetic powder clutches?

Printing, packaging, film converting, paper processing, textile manufacturing, lithium battery production, and wire & cable industries.

How is torque controlled?

Torque is adjusted by changing the excitation current supplied to the clutch coil, enabling precise tension control.

What is the difference between a magnetic powder clutch and brake?

A clutch transfers torque between rotating shafts, while a brake generates controllable resistance to regulate tension and speed.

Can magnetic powder clutches be used with tension controllers?

Yes. They are commonly integrated into automatic tension control systems for precise winding and unwinding operations.
