The power of permanent magnets
KEB permanent magnet clutches transmit friction-type torque in de-energised state. For switching, the system uses the power of the permanent magnets in the magnet and forms a magnetic circuit via the rotor and armature assembly. The high field strength of the rare-earth magnets enables transmission of high torque with the smallest space.
The friction-type connection is opened via the opposite-pole electromagnetic circuit, controlled so that the power effect of the permanent magnet increases.
Preferred usage sectors for permanent magnet clutches are applications with very high power-on times, such as air-conditioning compressors or for door and hatch systems.
