Abstract: A hoisting system for the installation of a wind turbine wherein said hoisting system comprises measures to achieve a load bearing connection to the tower of the wind turbine and comprises measures to move the hoisting system up and down along the tower wherein the hoisting system, when it is fixed to an already installed part of the wind turbine tower with said load bearing connection, is arranged to install or remove any of a tower segment, a nacelle, a generator, a hub, and a blade in one or more combined hoists or in a single hoist.

Abstract: A system comprising a receiving unit which is sensitive for electromagnetic radiation and one or more wind turbines, with a variable rotor speed, a rated power of more than 1 MW, a rotor diameter of at least 50 m, which one or more wind turbines are located at a distance of less than 20 km from said receiving unit and wherein said system is arranged for reducing the interference of the receiving unit by the electromagnetic radiation emitted and or reflected, by the one or more wind turbines, and in particular wherein said receiving unit comprises at least one antenna for receiving cosmic electromagnetic radiation in the frequency range between 10 Mhz and 250 MHz.

Abstract: Direct driven wind turbine includes a tower, a nacelle, a rotor blade, a radial flux generator with a stator and a rotor, wherein the lamination package of the generator is essential for the transfer of the torque in axial direction. By introducing this additional function to the lamination package, the generator can be provided without additional torque transferring housing. Preferably, the lamination package obtains this additional function by pressing together the laminations between the front plate and end plate by tensile bolts. This gives sufficient strength to transport the torque in axial direction through the laminations to the mounting points of the generator. Preferably, the laminations include cooling fins. Due to these measures the cooling of the generator improves and active cooling may become superfluous or the power can be increased. The housing of the laminations is an expensive, heavy and labor intensive part which is no longer required due to the invention.
