  • Patent number: 6911741
    Abstract: Wind power plant with a wind turbine with a turbine shaft with which a generator shaft, which can be an extension of the turbine shaft, is connected to the rotor (12) of an electric generator. The rotor is radially surrounded by a stator, the turbine shaft is journalled in two bearing housings with bearings arranged on a base at the top of a tower, the base is pivotable around a vertical axis, and a motor is provided to effect the pivoting. The generator shaft is integrated with or rigidly connected to a flexing turbine shaft, the stator and rotor are carried by the generator shaft, to allow the generator to follow the flexing movement of the turbine shaft and the stator is locked against turning by a non-rotatable coupling which transfers substantially no bending moment or axial force acting against the flexing of the turbine shaft due to the bending moment acting on the turbine shaft from its hub, the bearings being provided to allow flexing of the turbine shaft.
