The INTORQ spring-applied brakes BFK458 are single-disc brakes with 2 friction surfaces. The braking torque is generated by frictional locking using compression springs. The brake is released electromagnetically. Automatic braking without current.

During braking, the rotor is pressed against the friction plate with the aid of the compression springs. To release the brake, the coil in the magnetic part is put under DC voltage. The magnetic force generated in this way pulls the rotor away from the friction plate in the direction of the magnet against the force of the compression springs.

With the basic module E from INTORQ, it is possible to reduce the braking torque by making adjustments via the adjustment ring.

Important: The friction surfaces must be kept free of oil and grease!

    • Fixed bearing not required on brake side
  • long-lasting
    • High service life of the winding of the magnet part due to insulation structure according to thermal class F (155 °C)
    • Design for 100 % duty cycle (brake energized/unenergized).
  • Low maintenance
    • long, low-wear rotor/hub guide with proven involute gearing

  • Ventilation travel or wear monitoring by microswitch (from size 12)
  • Monitoring of the manual release function
  • other voltages and bores than standard on request
