Magnetic powder brakes

The brake has a control characteristic similar to that of a hysteresis brake and should be controlled steplessly using the exciting current.

Characteristic areas of application:

  • Tight winding
  • Winding control
  • Controlled braking
  • Soft start
  • Overload protection
  • Load simulation

 

TECHNOLOGY PRINCIPLE:

The magnetic particles arrange themselves along the magnetic field lines, thereby forming long particle chains. These increase the internal friction and thus generate the desired torque between the rotor and the stator. When the coil current is switched off, the particles arrange themselves on the inner side of the stator due to the centrifugal force of the rotor.

 

Characteristics of the brakes and clutches:

Stepless torque controllability using the exciting current

Considerably smaller design as hysteresis brakes with the same torque

Completely wear-free

Maintenance-free

Noiseless operation
