Lenze electromagnetically operated brakes (spring applied) generate their braking effect by use of their in-built compression springs. These are often used as a fail safe brake as their coil is energized by a DC voltage which pulls the armature plate away from the friction disc thus releasing the brake.

When the brake voltage is no longer supplied, the field in the brake coil collapses and the compression springs push the armature plate away from the coil and against the friction disc thus engaging the brake.

These spring applied brakes can act as a dynamic brake or a simple holding brake depending upon the application and required torque.

We stock a wide range of Lenze brakes at Webb-Elec including the following models: BFK458, BFK470, BFK457, BFK468, BFK557  BFK552 & BFK471.
