Description

Permanentmagnetic Clutches Automotive 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. Technical data Torque range: 0,4 … 80 Nm Diameter: 29 … 150 mm Operating voltages: 12 … 48 V DC KEB Permanent magnet clutches offer: ■ Zero energy consumption in frictional locking ■ Residual current-free separation ■ Switching with no torsional backlash ■ Easy system integration ■ Maintenance-free ■ Long service life
