The Electromagnetic powder clutch achieves at a low gate power a high torque being independent from the slip speed. It distinguishes itself by a simple structure, low weight and requires little place. This advantage makes it possible that the clutch can be employed in the solution of many technical problems. For the different applications are needed appropriate regulation and control devices. We can deliver such proven devices. The characteristics of the Electromagnetic powder clutches and brakes are a great advantage in the control engineering. By changing the exciting current intensity, the torque to be transferred can be adjusted.
