ABSTRACT:
The present invention concerns a wind power installation having a rotor with at least one blade and an adjusting device for the rotor blade. An adjusting device with more than one drive for one rotor blade is provided. By virtue of that arrangement each drive only has to furnish a corresponding fraction of the power output, it can be of a correspondingly smaller design configuration, and it imposes a correspondingly lower loading on the subsequent components.
