ROTOR LOCKS

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. Svendborg Brakes rotor lock units hold a global market leading position. 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. The units are engineered to handle the large output torque generated by the high ratios found in wind turbine gearboxes.

Svendborg Brakes operates with three types of Rotor Lock solutions

LSM – Manual driven rotor lock
LSA – Hydraulic driven rotor lock
LSL – Electrical driven rotor lock
