The AWE 52-750 is a 750KW direct drive turbine, with an up wind rotor. The rotor consists of three blades that can be actively and individually pitched over their full span.
The AWE 52-750’s elegant high tech energy conversion system produces electric power of an excellent quality with its slow running ring generator.
In direct drive turbines, the number of components has been reduced tremendously. The result is a less vulnerable machine. The rotor and generator rotate as one integrated unit, supported by a designed single bearing system.
The absence of a gearbox simplifies maintenance procedures. The use of a monocoque nacelle also allows “all weather” access to essential systems and controls due to internal access.
