The NedWind 40 is a stall controlled machine, but the 20 metre blades (made by NedWind) pitch hydraulically as a safety mechanism in strong winds. The turbine, with a site dependent rated capacity of 400-500 kW, has two generators of equal size and the patented yaw drive uses a cable slung around the tower top, rather than gears. As can be seen in the photo, the Nedwind 40 has two generators of the same size on a double outgoing shaft from the gearbox. A single speed version has been ordered specifically by the US client. The dual speed version has two small additional generators.
