ROBA-stop®-silenzio®: The quietest safety brake for elevator and stage drives

Dual circuit brake
Function monitoring possible
Easy installation
Preset air gap
Low noise level

The ROBA‑stop^®‑silenzio®brake is a spring-applied, electromagnetic safety brake.

ROBA‑stop^®‑silenzio^® is suitable for the following uses:

Use in elevator and stage drives
Secure reliable and safe hold in the event of a power failure or switch-off

The ROBA^®‑stop‑silenzio is a spring-applied, electromagnetic safety brake.

In de-energized condition, several thrust springs press against the armature disks. The rotor is held between the armature disk and the intermediate disk or the intermediate disk and the flange plate or machine wall via frictional locking. The braking torque is introduced into the shaft via the toothing of the rotors and the hub.

Due to the magnetic force of the coil in the coil carrier, the armature disk is attracted against the spring pressure to the coil carrier, and the intermediate disk is pushed against the collar of the distance bolts by the thrust springs. The brake is released, and the brake rotors with the hub can be released freely.
