A wind turbine assembly has a hub, a rotor blade, a bearing that can be installed between the rotor blade and the hub, and an adjusting device. The rotor blade is arranged on the hub so as to be rotatable substantially its longitudinal axis. The adjusting device comprises at least one electric adjusting motor, which drives a gear connected to the rotor blade by means of a drive pinion, a converter coupled to an electric network and controlling the adjusting motor, and a control unit for the adjusting motor. The adjusting device comprises means for producing a signal that depends on the adjustment position of the rotor blade and an evaluating unit for comparing the signal or a derivative of the signal. |
