Powder brake & clutch operation principle

2011-03-09

Powder brake & clutch operation principle:

When no current flows in the magnetic coil, powder is being attached to input drum side by centrifugal force as separate input drum and output drum. So the torque is not transmitted. If coil is exited by electric current, magnetic flux is generated, and then torque is transmitted by the friction between powder and working side.

Powder brake & clutch features:

1) Excitation current and transmitting torque is almost in proportion, also transmitting torque is controlled with wide ranges.

2) Regardless of slipped rmp, torque is excellently transmitted.

3) Torque by residual flux is very little and stopping stability is excellent.

4) It can operate with slipping state, for large capacity cooling with heat.

5) Take short repair time as it is dry-type, so can use it for long time without any adjustment.

6) It is friction clutch of based on the powder.
