The wind generator is the heart and soul of your windmill project. It is the wind generator that converts wind into energy. There are many types and brands of wind generators available for purchase. Some produce D/C voltage while others produce A/C voltage in both single phase and triple phase. I’ll get into the phase details A/C electricity a little later.

The basics of building a wind generator a relatively simple. The windmill blades spin, when the wind is strong enough, turning a rotor. Inside the rotor are a set of magnets. As the rotor spins the magnets pass by coils mounted on a stator. As they rotor spins, due to wind speed, it creates a magnetic field that pushes the charged particles out of the coils creating electricity. That is only the basics, so all you electrical engineers can add comments to go further into detail.

There are many factors to consider when building a wind generator. How much power do I need? How much wind will I require to achieve the power needed? How tall should I build my tower? With those questions in mind, I suggest getting a book from Hugh Piggott called Windpower Workshop. He explains all the math in detail for a fairly easy DIY(do-it-yourself) windmill.

To build a wind generator you will need several components.
* Stator= This will be the stationary portion of the wind generator that will hold the windmill magnets

* Rotor= This will spin with the blades and will have copper coils attached to create electricity

* Rectifier= This device will convert A/C electricity into D/C electricity to be able to store power in a Battery bank created by your wind generator

Note: The size of the stator and rotor will depend on your application and will need to be custom made. These are made of steel. in order to produce 1000kwh monthly they should be 12″ in diameter and 1/4″ thick.

Building a wind generator is not for everyone. But owning a wind energy system is possible. If this sounds like a project you can handle then the book from Hugh Piggott called Windpower Workshop. If you are interested in buying a wind energy system, How To Make A Windmill suggests the 400W/12V WindMax High Efficiency Wind Generators – Wind Turbine Systems
