Building a Wind Turbine
This wind turbine was not built following exact plans, instead the information from a selection of books and online resources was pooled and the turbine built accordingly. Of particular use was Hugh Piggot's book Windpower Workshop which is essential reading.

Wind Turbine Blades



First the wooden wind turbine blades were carved with an efficient aerofoil section and twist much like a propeller. Three 1.7 metre long blades were hand-carved (following calculations from Windpower Workshop) aiming for a tip speed ratio of 8, and a rotation speed of 450 rpm in a 22mph wind.

The Alternator (Generator)
The generator was designed with a 24 Volt three phase stator (3 coils each phase) and two rotors with twelve 46x36x12mm rectangular shaped NdFeB (Neodymium) magnets each. The hub and rotor assembly was built out of scrap 1995 BMW front strut with a pair of brake discs.
