Abstract
The invention relates to a wind turbine of the horizontal axis, direct-drive type, wherein the wind turbine comprises a hub provided with one or more blades, a generator with a centerline that is technically horizontal, the generator comprising an inner rotor which is driven by the hub and an outer stator, the stator comprising a front plate, a back plate and stacked, arcuate laminates. The wind turbine according to the invention is characterized in that the front plate and the back plate are connected by tension rods so as to form a stator unit with the stacked, arcuate laminates being sandwiched between the back plate and the front-plate under compression, wherein of a first arcuate laminate in contact with a second arcuate laminate stacked against it the outer edge of the first arcuate laminate is at a larger distance from the centerline of the generator than the outer edge of the second arcuate laminate so as to increase the outer surface area of the stator for dissipating heat to the atmosphere. The invention also relates to a direct-drive generator.
