KEB COMBIPERM Permanent Magnet Brakes and Clutches

KEB Combiperm P1 brakes provide power-off brake engagement with electromagnetic release. KEB P1 brakes are designed using rare earth magnets which allow for very high torque densities in small diameters.

P1 permanent magnet brakes have zero backlash and operate across a wide range of operating temperatures and voltages — this makes them ideal for the most precise and demanding applications.

Servo Motor Brakes

KEB P1 permanent magnet servo brakes are preferred by servo and stepper motor manufacturers because they offer:

  • Power-off brake engagement
  • Zero Backlash
  • High brake torque density per diameter
  • Large temperature tolerance – Nearly constant torque at high temperatures
  • High maximum operating speeds
  • Large torque ratings – Up to 145Nm

Robotic Arm Brakes

KEB permanent magnet brakes are used in the most demanding and high-cycle robotic arm applications. Some advantages of the P1 robotic brakes are:

  • 24VDC operation (other voltages available upon request)
  • Zero Backlash
  • High duty cycles supported
  • Flexible mounting configurations
  • Low Inertia
  • Horizontal and vertical mounting

Typical Applications

  • Servo motors
  • Robotic arms
  • Medical machinery
  • Industrial machinery
  • Machine and CNC tools
  • Semiconductor machinery
