The invention relates to a wind turbine comprising a rotor (70) on which rotor blades (30) can be mounted, an electric generator (60) which has a generator stator (100) and a generator rotor (200), and provided with a plurality of displacing units (300). The first end of the displacing unit is removably fixed to the generator stator (100), and the second end of the displacing unit is removably fixed to the generator rotor (200). Each of the displacing units (300) has a hydraulic cylinder (320), the deflection of which can be controlled such that the generator rotor (200) is displaced relative to the generator stator (100) by actuating the displacing units.
