INTORQ BFK458 spring-applied brake
Torque range: 1.5 – 600 Nm
Electromagnetically released spring-applied brakes are used wherever masses in motion have to be decelerated as quickly as possible or where masses must be held in a defined position. The braking force is applied by tappet springs. Thus the braking torque generated by friction locking remains available in the deenergised status – even in the event of mains failure. The brake is released electromagnetically.

Fields of application
Brake motors, Conveyors, Cranes, Storage technology, Industrial trucks, Wood working machines, Stage machinery, Vehicles for the disabled, Automation technology, Controlled drives, Gate drives, Escalators.

    Torque transmission
  • Designed for dry running

    A powerful and complete range
  • 9 sizes
  • Standard voltages [V DC] 24, 96, 103, 170,180, 190, 205
  • Graduated torque range from 1.5 - 600 Nm
  • Enclosure according to IP00 ... IP55, depending on the special operating conditions

  • Hand release for all sizes, both directions can be used for release and mounting (exception: tacho brake)
  • Noise-reduced designs
  • Various types of corrosion protection and enclosures
  • Microswitches used to monitor air gap and wear (size 12 and above)
  • Monitoring of Hand release function
  • Non-standard voltages and bores on request
  • Pulse width modulation (PWM), sizes 06 – 18 Partial discharge free brake has been developed for operation with the pulse width modulated DC bus voltage of a frequency inverter Rated coil voltage UN=103V DC

    Quick and easy mounting
  • Preset air gap
  • Special machining of the friction surfaces ensures that the rated torques are achieved after very few switching operations
  • No locating bearing is required on the brake

  • The insulation system to temperature class F (155°C) ensures that the winding has a long service life
  • The brakes are designed for 100% duty time (current applied to the brake)

    Low maintenance
  • Long rotor/hub connection with low rate of wear and a tried-and-tested involute gear
  • Asbestos-free and solvent-free friction lining with low rate of wear

    Long Life design BFK458-L
  • Armature plate with low backlash and reinforced torque support
  • Tappet springs with guide pins for protection against shearing forces
  • Aluminium rotor with toothed intermediate ring: friction lining and tooth system with low rates of wear.

    CCV (Cold Climate Version), temperature resistant up to -40˚C
  • CCV design configurable for all sizes in the modular system
  • Use of chrome-plated friction surfaces (armature plate and flange)
  • Use of temperature-resistant fixing screws is essential

    The following components are also approved for use up to -40˚C
  • Rotor with sleeve (noise-reduced)
  • Hand release
  • Terminal box
  • Microswitch
  • Caps E and N

  • Shaft sealing rings (available on request)
