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.
|Torque range||0,1 … 80 Nm|
|Diameter||29 … 150 mm|
|Operating voltages||12 … 48 V DC|
KEB Permanent magnet clutches offer:
- Compact design
- Easy system integration
- Rare-earth magnets with high energy density
- De-magnetizing and corrosion resistant
- Free from torsional backlash and maintenance with long service life
- High temperature range
An alternative to power transmission with permanent magnets are KEB spring-operated brakes, available for use with braking torque up to 1500 Nm.
