Abstract
A wind turbine of the horizontal axis, direct-drive type, 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 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, the arcuate laminates having protrusions over the circumference of the stator for dissipating heat to the atmosphere. The invention also relates to a direct-drive generator.

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, wherein 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, the arcuate laminates having protrusions over the circumference of the stator for dissipating heat to the atmosphere.
A direct-drive generator comprising an inner rotor and an outer stator, the stator comprising a front plate, a back plate and stacked arcuate laminates, wherein 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, the arcuate laminates having protrusions over the circumference of the stator for dissipating heat.
