A tower segment, in particular for a tower of a wind turbine, a wind turbine, and a method for manufacturing a tower segment is provided. A tower segment, in particular for a tower of a wind turbine, comprising a casing segment with an inner casing surface, an outer casing surface and a cutout for a door, wherein the inner casing surface has a first inner reinforcing portion and/or the outer casing surface has an outer reinforcing portion, wherein the inner reinforcing portion and/or the outer reinforcing portion adjoin the cutout, and the inner reinforcing portion has an inner reinforcing plate and/or the outer reinforcing portion has an outer reinforcing plate.

Tower segment and manufacturing method

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.
