More Information
Summary:Adjustment and/or drive units that can be used in wind turbines to set the azimuth angle of the wind turbine nacelle or the pitch angle of the rotor blades, wherein such an adjustment and/or drive unit has at least two actuating drives for rotating two assemblies, which are mounted for rotation relative to each other, and has a control device for controlling the actuating drives, which control device controls the actuating drives in such a way that the actuating drives are braced in relation to each other during the rotation of the two assemblies and/or at a standstill of the assemblies. The invention further relates to a wind turbine having such an adjustment and/or drive unit and to a method for controlling such an adjustment and/or drive unit.
