Before we can build our wind turbine there are a few tools we need to make. We’ll need to make moulds for the magnet rotors and the stator, and we need to make a coil winder. It’s simply a spool made from wood, with a crank that we can wind our coils on. The next couple of pages will detail exactly how we made ours, but the idea here is simple and there are surely many simpler ways to do this. Some of the thoughts that went into this design included… having a fairly large crank which makes handling thicker wire easier, and having the back disk oversized, with steel pins so that we can change the form of the coil
and build different/larger sizes of coils if necessary . Ours is also constructed like this because these were all materials we had on hand. Your situation may be different. For a one off project, this could all be simplified some. Before building this it might be helpful to read the section on building the stator so you understand how we use this tool – that will help you to understand why we make it this way, and give you ideas about other possible ways to make a good coil winder. Listed below are all the parts we’ll require for this project.
