ROBA®-servostop® Classic: Classic spring-applied safety brake for servomotors

  • High braking torque
  • Wear-resistant - large number of emergency stops allowed
  • Easy installation

Classic series for installation both in the A-bearing side and the B-bearing side of servomotors.

The ROBA®‑servostop® Classic is a spring-applied, electromagnetic safety brake.

When the brake is closed, the rotor with the friction linings is held between the armature disk and the flange plate. When the power to the installed magnetic coil is switched on, the magnetic field pulls the armature disk against the force of the springs towards the coil carrier. The brake is released.
