Recently Lenze separated their brakes division ‘Lenze Bremsen GmbH’ into a new company and this new company goes by the brand name of Intorq. Lenze no longer manufactures these products. In accordance with its background, INTORQ continues to set the international standard for brakes and clutches. Identical products with the same designations and order numbers as those of Lenze are now available from INTORQ. Internationally Intorq continues to work closely with the worldwide sales organization and service teams of Lenze.

  ●  Multipole Spring operated brakes- Intorq BFK468  
 
          


High-performance drives are generating ever higher motor speeds and drive torques. Although performance requirements are increasing, less and less space is available for the brake. The INTORQ spring operated brake for high-performance applications is the BFK468. The innovative multipole technology allows it to be released through a large air gap, even when forces are high.

  
       
  Æ  Features  
       
    ● Spring-operated brake with multipole system  
    ● Up to twice the braking torque compared to the BFK458  
    ● Fixed or adjustable braking torque  
    ● “Cold brake” by holding current derating  
    ● Short operating times on AC side  
    ● Large working air gap means long maintenance intervals  
 
  ●  Multi-pole spring-operated brake, the solution for direct drives in passenger lifts-BFK466  
 
         


Direct drives for modern hoists demand brakes with high braking torques, short response times and low-noise operation. The multipole BFK466 satisfies all these requirements and can also be adapted to the contour of the motor.

  
       
  Æ  Features  
       
    ● Spring-operated brake in the form of a caliper  
    ● For multiple and redundant arrangements  
    ● High braking torque and large working air gap  
    ● Release without residual torque and quiet operation  
    ● Optimal contour adaptation to the design of the motor  
    ● High magnetic forces caused by overexcitation when releasing  
    ● “Cold brake” through holding current derating  
    ● Air gap or wear monitoring using micro switch  
       
  ●  Brakes for Safe raising and lowering of hoists- Intorq BFK454  
 
          


This dual-circuit spring-operated brake is specially designed for geared motors in lift applications. It ensures safe operation as a holding brake and for emergency stop duties. It is TÜV tested and satisfies the TRA200 requirements for hoists.
 
  Æ  Features

  ●  Spring operated brakes for servo Motors: BFK418  
       
          


Servo drives require holding brakes that have short operating times and very little torsional backlash. The temperature-resistant friction linings of the brakes are also ideally suited to handle emergency stops from high speeds. This makes the low-cost BFK418 a viable alternative to permanent magnet brakes, and not just froma technical point of view.

  
       
  Æ  Features  
       
    ● Braking torque: 5–150 Nm
