Before you begin your DIY wind generator project, you need to learn the ins and outs of design and construction of a wind turbine.
Don’t worry, its not rocket science; although it can be in some situations. In general, the design and development of a DIY wind generator is simple and straight forward. The only real complexities in the design phase have to do with how much power you can feasible generate with a given wind speed and purity in your area.
This is a little more difficult to explain, but the maximum amount of power you can get out of a wind generator will depend on many factors that can either work in unison or against each other. The first factor is the wind itself. You really need a stead source of wind locally and this wind needs to be as pure as possible in order to generate any usable wind. The concept of wind purity has to do with the amount of turbulence in the wind as turbulence can create many hassles with the operation and efficiency of a wind turbine.
The second factor has to do with capturing that wind and converting its lateral force into a rotational one. If only a DIY wind generator could use the lateral forces of the wind directly. Unfortunately, you generator will need to spin and in order to convert these forces, you need blades that are designed for your particular generator and circumstances. The blade needs to be designed for collecting the wind and therefore electric fan blades will not be efficient at all.
Finally you have what is known as back EMF. If you have ever tried to turn a high-torque electric motor and felt those lobbed parts of the rotation, this is back EMF. As magnets pass one coil, the other coils become charged and magnetized. This force can prevent the DIY wind generator from spinning. Many builders opt to construct this generators using multiple phases so as to separate this back EMF and reduce its potential to create friction in the turbine system.
Furthermore, the coils themselves are dependent upon the gauge of the wire used in their construction. The larger the diameter of the wire used, the more power that can be created but at the same time, the more back EMF that is generated. The smaller the wire, the more freely the DIY wind generator is capable of spinning, but as a result the less power that the system is able to produce with a given wind speed.
If you take the time to learn more about these individual concepts, then making a DIY wind generator will be so much easier.
