Electromagnetic particle brake - 0.007 - 1 000 Nm

Electromagnetic particle brake - 0.007 - 1 000 Nm
mobac Magnetic particle brakes and clutches are of simple design. Due to their size they produce a high torque compared to for instance hysteresis brakes. They are having two rotors (inner and outer) and an air gap between these two rotors where the magnetic particles are dispersed in. An electric current passing through the coil creates a magnetic field, which aligns the magnetic powder into the gap. The higher the current, the more rigid the connection between the inner and outer rotor becomes. The principle is the same for brake, clutch and torque limitor.

Advantages:

Noisless work
Torque directly proportional to current
Torque independant from r.p.m. (starting from 30 min)
Strong design, units are able to be used with steady slipping
High torque range to be controlled (approx 1:50)

Applications:

Braking
Torque control, torque limiting
Tension control at winding, unwinding
Starting clutch operation
Calculated braking and starting
of certain masses and inertias
