The ROBA®‑stop®‑S is a spring-applied, electromagnetic safety brake.
In the de-energized state, the compression springs of the ROBA‑stop®‑S press against the armature disk. The rotor is held between the armature disk and the flange plate. The shaft is braked via the toothed 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. The brake is released, and the shaft can rotate freely.
