Learning How to Build a Wind Generator is Easier Than You Might Think

Life can be tough sometimes and you may be looking for ways to make it easier and less expensive. Since energy, especially electricity is one of your more expensive everyday expenses, would not it be great if you could tap into the renewable energy that is all around you? Wind energy is already benefiting much of the world, so why can not you take advantage of it, too? All you need is a wind generator. But do you know how to build a wind generator?

That is a good question. Here are some simple steps to help guide you:

– Location, location, location. You will need an open area with at least a three hundred to four hundred foot radius. You also need to watch for any obstacles since since the tower can reach 30 to 40 feet high. A tilt-up tower is best for low areas since they are closer to the ground. This also makes them easier to maintain. However, a free standing tower will maximize the output since it is taller and has fewer obstructions.

– Secondly, focus on the materials needed, first of which is the motor, which converges the wind energy. It is a must to find a DC motor that is intended for high voltage, with low rpms, and high current.

– Then comes the blades of the wind generator, which can be carved from plastic, wood, sheet metal or you could also use PVC pipes. Note that the longer the blades are, the wider its swept area covered, meaning the more power it can extract from the wind.

– Next you need to connect the blades to a shaft which, in turn, connects to the motor. This is done with a hub. The hub can be made from a steel disk that you can drill holes into. Attach the blades to the hub, the hub to the shaft, and the shaft to the motor.

– In order to keep your wind generator turned to the wind, you need to make a tail and pivot. You can use some scrap sheet metal for the tail and a flange for the pivot, along with some square tubing and pipe nipple.

– One last, important step to cover for your wind generator is the battery. The wind does not always blow, so you need a way to store the converted energy. Try to keep the batteries as close to the generator as you can in order to monitor the charging. Try to get batteries that are highly efficient, yet low maintenance.

"Deep cycle" batteries are best used for this type of power system application. They are rated in amp-hours and have indicators of their charge-discharge cycles.

Once you have learned how to build a wind generator, you will need to place a diode between the generator and batteries. This is to prevent the energy from flowing back into the generator and being wasted. A secondary load to act as a depot for excess energy produced would also be a good idea.
