The FAIRWIND windturbine is made of :

1. A self supporting structure without stay ropes. The height depends on the type of mast :
   • Either a metallic mast in one or several parts to be fitted on a concrete foundation
   • Either a smaller structure to be installed on an existing building
2. One rotating unit including bearings and coupling flanges parts on the supporting structure.
3. Two or three arms connecting the blades to the rotating unit for torque transmission.
4. One electric box including the frequency converter, the regulation device and the protection system. The converter rectifies the variable frequency current and generates good quality 50 or 60 Hz current to feed the network.
5. Two or three constant chord blades of continuous structure, made of a light alloy.
6. One synchronous permanent magnet generator regulated to adapt constantly the wind turbine rotation speed to the wind speed and maximise the energy recovery (Maximum Power Point Tracking).
7. One reinforced concrete foundation designed to resist the heaviest winds.
