BFK468 SERIES

Multipole Spring Applied Brake

The new performance standard 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.
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
