EMP (Electro Magnetic Particle) Brakes & Clutches Principles
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
