The AWE 54-900 is 900KW 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 54-900’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.

The AWE 54-900 turbine is available in two configurations.  A 54 meter rotor diameter machine for Class III wind conditions.  A 52 meter rotor diameter machine (the AWE 52-900) is also available for Class II higher wind conditions.

The AWE 54-900 comes in three versions: 

            AWE 54-900-40          with a 40m tower
            AWE 54-900-50          with a 50m tower
            AWE 54-900-75          with a 75m tower
