Wind energy installation and method for production of electrical energy from wind energy by means of the wind energy installation having a rotor which can be driven via wind power and has rotor blades whose pitch angles can be adjusted by means of at least one adjusting apparatus, which can be driven electrically, in order to influence the rotational speed of the rotor, wherein a generator rotor is connected to the rotor, and the generator rotor together with a stator forms a generator, and wherein a magnetic field which rotates with respect to the generator rotor is produced by the stator and, by interaction with the generator rotor, which is stationary with respect to the pod, induces a current flow in the generator rotor in order to operate the adjusting apparatus. |
