Generator for a direct-driven wind turbine.

摘要

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.
