Active rotor brakes

Active rotor brakes are part of the aerodynamic braking system of the rotor of a wind turbine. Active rotor brakes are hydraulic applied and spring released, meaning that the braking force depends on the hydraulic pressure.

When the turbine is in operation, the active rotor brake is without hydraulic pressure and the brake linings are retracted by springs.

Active rotor brakes are used as an emergency brake and for positioning the rotor to apply rotor lock devices for mechanical locking during maintenance.
