overview

The EMP powder reacts to the variation of a magnetic field generated by a coil.

Varying the powder's "viscosity" leads to the control of the torque transmission between the primary and the secondary rotors.

When the secondary rotor is fixed to the equipment frame, the device is acting as a brake.
When the secondary rotor is free to rotate, the device is acting as a clutch.

features

The torque is proportional to the electric current

The torque is independent of slip speed

- Reliable, stable torque without chock nor noise
- Low residual torque
- Continuous slip
- Bi-directional rotation
- Low wear, long life-reduced maintenance
- Dust free
- Thermal dissipation increased by the installation of cooling fins (radiator)
- Fast response time
- Low electric power control
- Easy remote control
- Linear smooth, silent
- Easy to integrate in any type of system
