Powder clutches/brakes
All-around ideal performance
We use a special magnetic powder to transmit and control the torque on this series of clutches/brakes. The original powder and advanced structural design create incomparable performance in torque control and slip usage. Our unique materials and manufacturing expertise produce a high quality, nearly spherical powder, which dramatically improves the performance and reliability of our product, truly making this the ideal powder clutch/brake.

Features
1. High precision torque over a wide range of values
By using efficient magnetic circuitry, the transmitted torque can be varied between 3% and 100% of maximum rated torque.
2. Stable torque and long operating life
The ideal spherical powder obtains stable torque and smooth slip operation.
3. High thermal radiation capability
Using a heat resistant powder, and a structure with high thermal radiation capability, our devices are capable of heavy continuous slip operation.
4. Non-shock, smooth linkage and brake
Achieve an excellent buffer effect with its constant torque and smooth slip torque.
5. Non-abrasive powder and silent operation
Unlike abrasive clutches/brakes there is no wearing powder, and silent operation is possible since there is no linkage sound.
6. Rapid response
The generated magnetic flux operates instantaneously as the effective flux, providing rapid torque response.
