Lenze INTORQ BFK 466 Spring-Applied Calliper Brake for Elevator Applications Distributor


With its broad scope of different versions, the modular range of INTORQ products is used in many motors and geared motors and has set standards worldwide. With the establishment of facilities in Shanghai and Atlanta, we have also consistently expanded our international presence. So wherever you are in the world, our network of sales and service staff is always close at hand to support you.

When using brakes in lift systems, safety is the top priority. We offer you specific solutions for various drive concepts in the field of lift technology.

Whether geared motors or direct drives - our brake systems are precisely matched to your specific requirements. The BFK464-S dual-circuit brake with multi-coil technology has, for example, been optimised for fitting to the new generation of compact direct drives. Also, the kidney-shaped brake callipers of the BFK466 with multi-coil technology have been ideally matched to the contours of axially-short motors and are capable of generating high levels of braking torque.

If you are looking for INTORQ BFK466 Brakes, please call us at (844) 331-9371 or email us at we will do our best to help you find the INTORQ BFK466-12 spring-operated brake that you are looking for at the most competitive prices possible. If you are searching for INTORQ BFK 466-22 brakes technical information (data-sheets) please use the datasheets or product selection guide page links.

The most important properties of INTORQ brake systems for lift applications:

  • Redundant brake systems
  • Long-term reliable noise reduction
  • Stable braking torque, even with friction surfaces at high temperatures

Direct drives for modern lift technology require brakes with high braking torques, fast response times and low levels of operating noise. The BFK466 with multi-pole technology satisfies all of these requirements and can also be adapted perfectly to the contour of the motor.


  • Spring-applied brake designed as a calliper
  • Redundant by multiple arrangement
  • High level of braking torque and large working air gap
  • Zero residual torque release and quiet switching
  • Optimum contour matching to the motor design
  • Cost optimized excitation due to bridge/half-wave rectifier (necessary)
  • Fast switching times thanks to low brake inductance
  • Release or wear monitoring with microswitch
  • Type tested

The Energy-Saving Function "VFC eco" supported by the 8400 reduces the energy required by the motor in partial load operation. Combine this with an MF L-force three-phase AC motor (inverter-optimised, 120 Hz) and what you get is a highly efficient, compact and cost-effective drive with high dynamic performance and a wide setting range. "VFC eco" can reduce your energy costs by up to 30%.

Magneta Clutches

The Stator with a Flange must be assembled concentrically to the shaft. For this, use the outer flange diameter or the housing bore. The rotor of the clutch is assembled on the shaft using a key connection and is secured axially. If there is no suitable mounting surface for the flanged stator, use shaft-mounted clutches. The stator is bearing-mounted onto the rotor. A pin with sufficient tolerance
