Thinking Wind Power? Learn Why Buying Cheap Wind Turbine Components Is Not Always The Best Option An

In these tough economic times, we are all looking to save money whenever we can

. Adding wind power can be an energy saving add-on to your home if you live in a strong wind zone. However, buying cheap parts to build your wind turbine or buying an inexpensive wind power kit may not produce the home energy savings you are hoping for.

A wind turbine consists of the tower, control panel, mounting, generator, and the wind blades. That seems simple enough to build from scratch, but the most advanced commercial wind turbines are designed with computers to maximize energy production.

Here are the wind turbine parts you should focus on if you want to maximize both your investment and energy production:

The Generator: Along with the wind blades, the generator is one of the most important components of a wind turbine. It generates electricity by reversing the direction of a DC motor shaft attached to the wind blades. If funds are tight, you can use a car alternator, old electric lawn motor, or the DC motor in your power tools. However, the energy produced may not be as much as you'd like.

When deciding which generator to purchase or convert, it may be a good idea to invest in a good generator like those produced by Ametek if you are serious about wind energy production. Focus on the size of the motor, amps, voltage, and a generator with a low RPM rating of 400 or less which produces 12 volts or more.

With a low RPM rated generator, more electricity is produced with lower wind speeds. So unless you live in an area with high winds, or planning to generate your energy production from multiple hurricanes, an RPM rated generator under 400 RPM is usually your best option.

Attaching a larger hub to your wind blades and using a belt to the generator, similar to the gearing of a bike, may produce more electricity for a low cost, high RPM rated generator. However, this setup will require more torque from the wind blades, which will lower your RPMs. Test out the hub configuration that works best to maximize your energy output.

Wind Blade: The wind blade is another important wind turbine part that generates RPMs by capturing the wind, which is offset and slowed by the wind resistance of the blades. Blades, which are homemade, can have poor RPM efficiency if they are not balanced correctly, which will add additional stress to the generator shaft bearings.

The most expensive wind turbines use the three blade configuration due to low wind resistance, good balance, and efficient wind capture to maximize RPMs.

If you are using a larger hub to counter a high RPM rated generator, using five blades to increase your wind power torque at lower RPMs may work best. Again, test and see which maximizes your results as five blades will encounter more wind resistance and result in a lower RPM.

Although making your own wind blades may be a fun project to accomplish and give you an inexpensive wind turbine, manufactured blades made out of carbon fiber which are computer designed can be purchased for a relatively low cost and produce more electricity.

Taking the inexpensive route on wind turbine parts may be the best path in the short run, but choosing to purchase quality parts at relatively low cost can provide you with a wind turbine that will last longer and provide you with more usable energy for your home in the long term.
