Abstract: The invention relates to a method for operating a wind turbine comprising an aerodynamic rotor that has at least one rotor blade. Said method comprises the steps of operating the wind turbine at an operating point that depends on the wind speed, detecting an operating parameter of the operating point, comparing the detected operating parameter with a predetermined reference quantity, and heating the at least one rotor blade when the detected operating parameter exceeds a predetermined variation from the reference quantity, the operation of the wind turbine being continued.

Abstract: There is provided a wind power installation rotor blade comprising a rotor blade nose, a rotor blade trailing edge, a rotor blade root region for fixing the rotor blade to a hub of a wind power installation and a rotor blade tip. The rotor blade extends from the rotor blade root region along a longitudinal axis to the rotor blade tip. The rotor blade further has an air distribution unit having an adjusting member for directing an air flow into the rotor blade nose region and/or a rotor blade trailing edge region.

Abstract: The invention relates to a laminated core assembly of an electric generator, in particular of a generator of a gearless wind turbine. The laminated core assembly comprises at least one laminated core, at least one winding arranged around the laminated core, and an electrical insulating means arranged between the laminated core and the winding, wherein the insulating means has a composite material for conducting the heat arising in the winding.

Abstract: The invention relates to a pole shoe of an electrical machine, in particular a rotor of an electrical generator of a wind turbine generator system, comprising a pole shoe body for conducting a magnetic field and for receiving a winding for conducting an electrical current, in particular an excitation current, for producing the magnetic field, and at least one heat sink, entirely or partially surrounding the pole shoe body, for cooling the pole shoe, wherein the heat sink is arranged between the pole shoe body and the winding.

Abstract: There is provided a wind power installation rotor blade comprising at least one electrically operable heating mat which is fixed in the interior of the rotor blade.
