Magnetic Particle Brakes

Magnetic Particle Brakes with shaft

Shaft-mounted magnetic particle brakes offer precise torque control that is proportional to the excitation current. They are robust, designed for continuous slip and ideal for applications that require reliable tension control, such as in film and paper processing.

Information on working methods

Details

The Magnetic Particle Brakesare designed for a temperature range of -20 to +80 °C.

Precise torque control through magnetic particles
Torque range: 0.2 Nm to 5 Nm

These standard units are designed for horizontal operation, speeds between 60 and 3000 min are possible, whereby the permissible power loss must be taken into account. The installation must be carried out without any tensioning; if necessary, a flexible coupling must be used.
