The power of permanent magnets

KEB high performance permanent magnet brakes transmit torque by friction with no torsional backlash.

Permanent magnets generate a force field raised (opened) by the magnetic coil of the opposite pole when current is supplied and, in conjunction with the spring on the armature element, ensures separation free from residual torque irrespective of installation position.

A further advantage of permanent magnet brakes is high torque transmission within a small space. 
KEB permanent magnet brakes are particularly suitable for door/hatch Systems.
