Power-Off Engaged Brakes for Conveyor Applications

Miki Pulley’s latest model BXW power-off engaged brakes offer multiple conveyor line applications. These spring-actuated electromagnetic brakes are designed to provide dynamic braking when conveyor power is disengaged and ensure performance for longer-term holding requirements for staging, loading, and unloading conveyor operations. BXW brakes work by using internal compression springs to provide power-off, fail-safe braking. The primary moving part in this design is the armature plate.  When actuated, the brake’s compression springs push the armature plate into the friction disc when power is disengaged. This feature provides fail-safe braking and allows the brake to maintain position over long periods of time, thus preventing a conveying system from “coasting” when powered off.
