Optimum generator cooling
A my!WIND's nacelle is far more than just a cover.
The nacelle not only protects component groups such as yaw mechanism or ring generator, it also leads approaching air flow right where it is needed to cool down the generator: Around the ring generator's surface air flow speed is very high. A following reduction in size creates suction, which keeps the air flow at the generator close to its cooling ring's surface. It is easy to recognise a my!WIND's cooling ring by its green colour.
Thanks to a centre of mass at its very rear, the my!WIND nacelle widely protrudes into wind direction. At its rear there is a cover that houses both rotor hub and the blades' pitch mechanism.
