ACTIVE ROTOR BRAKES

ACTIVE ROTOR BRAKES

Rotor brakes are an essential safety-feature of wind turbines.

They are used for protection against overspeed as well as for stopping and holding the rotor, e.g. for maintenance purposes.

Depending on the drive concept, the brakes can be installed on the low speed rotor site, e.g. in gearless drives or on the high speed side at the gearbox output shaft.
