Rotor Locks


Svendborg Brakes rotor lock units hold a global market leading position
Rotor locks are used in the wind turbine industry and are typically mounted to the turbine´s main rotor shaft, between gearbox and generator. A rotor brake is primarily intended for use as safety brake during emergency stops under high wind conditions.

The rotor lock is activated by running the lock bolt into the lock disc using hydraulic power; a "locked" signal is then transmitted to the control system.

All Svendborg Brakes rotor lock units are engineered to handle the large output torque generated by the high ratios found in wind turbine gearboxes.

 Key benefits of Svendborg Brakes' rotor locks for wind turbines:

  • Compliance with safety regulation (e.g. requirement for form-fit locking)
  • Suitable for extreme wind load situations
  • Reliable and proven design on thousands of turbines
  • Monitoring capabilities by visual and/or electrical sensors
  • Hydraulic or Mechanical activation
  • Fully automated rotor lock engagement available
  • Best in class corrosion protection
  • Full engineering support from first samples to serial deliveries
