Abstract
The invention relates to a wind power plant (W) with a rotor, which is in operative connection with a gearbox (13) via a rotor shaft (12), wherein in particular the gearbox (13) is in operative connection with a generator via a main drive (19). Moreover, the invention relates to a method for the operation of a wind power plant (W) with a rotor and use of a driving device. The wind power plant (W), with a rotor, is further established in that the gearbox (13) has an auxiliary drive (30) and in that a rotor positioning rotating device (24) is arranged on the auxiliary drive (30) so that using the rotor positioning rotating device (24) and the auxiliary drive (30) of the gearbox (13), the rotor of the wind power plant (W) is positioned, and wherein the auxiliary drive (30) cannot be switched within the gearbox (13).
