Claim Text:
1. A wind power installation comprising: an aerodynamic rotor configured to have rotor blades fixed thereto and removed therefrom; an electric generator having a generator stator and a generator rotor, the generator rotor being directly coupled to the aerodynamic rotor; and a plurality of displacement units, each having a first end that includes a bracket directly and releasably fastened to the generator stator and a second end that includes a fork directly and releasably fastened to the generator rotor, each of the displacement units having a respective hydraulic cylinder between the fork and the bracket, wherein a deflection of each of the hydraulic cylinders is controllable and causes a displacement of the generator rotor relative to the generator stator whereby rotation of the aerodynamic rotor is effected, wherein the bracket and the fork are fastened to the generator stator and the generator rotor, respectively, while rotor blades are being fixed to or removed from the aerodynamic rotor.
