Build a Wind Turbine

An update from Duncan:

This is a photo of the stator we’re making for our 1.8 metre diameter Hugh Piggott wind turbine. I thought you might like to see it.

For those of you who don’t know what this object is and does

Two weeks ago we laid the coils of wire we’d made in the plywood mould (also made by us) and poured in polyester resin to make the rigid stator casting. On Tuesday we opened our stator mould, removed the casting and got our first look at what we’d made.

The stator contains six coils of wire, now sealed in a disc shaped casting of now set and solid polyester resin. The stator is bolted to the turbine frame. A rotor disc mounted on ball bearings holds eight magnets and spins over the six coils. The movement of the magnetic field from the magnets past the coils generates electricity.

Long flexible wire “tails” lead out of the casting and connect the coils together to generate three-phase electricity.

The magnet rotor is bolted to, and thus turned by, the wind turbine blades.

Members of Transition Worcester are planning to build a wind turbine. They will be using a tried and tested design produced by Mr Hugh Piggott who has designed homemade wind turbines for people in many countries.

They would welcome anyone  who would like to join them in making this turbine.
