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

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

  • Slim design
  • High performance density
  • Low energy consumption
  • Easy installation

Slim brake for installation both in the A-bearing side and the B-bearing side of servomotors and as a robot brake for installation in joints of lightweight robots.

Operation with overexcitation and power reduction.


The ROBA®‑servostop® Lean 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.
