A good set of plans should thoroughly explain which materials to use. The plans should also give you options and formulas for the size of your windmill generator. The size should be determined by electrical demand and available wind speed. You should know what type of motor to use for your windmill, and why.

Materials

The materials will vary upon application of the windmill. The shear wind force on your blades will determine what material you make your blades from. If your using PVC pipe for your blades and not reinforcing the blades at the hub, your more than likely going to snap a blade. This isn’t a huge deal, unless your windmill is placed in a hard to reach location. Sometimes you’ll want to sacrifice a little efficiency for less maintenance. A good set of DIY plans will cover materials.

Wind Formula Calculations

Your available shear wind speed wil determine the most efficient windmill generator for your applications. A huge windmill that doesn’t spin does you absolutely no good. The wind calculations will determine the length of your blades. This isn’t complicated but it’s good to know for efficiency. Those who are blessed with high winds, may need to include a break, or furl design, to keep from damaging your windmill.

Type Of Generator

A common misconception is that a car alternator would make a good wind generator. This isn’t true. A car generator needs to spin way to fast. Wind generators need motors that produce the most electricity whith the least amount of rotation, and at low speeds. Low RPM high voltage 3 phase motors, are commonly used. A good set of plans will tell you what motor to use for your needs.

DIY wind generator plans are a great alternative to paying high prices for wind generators. The wind turbines can be easily fashioned from readilly available materials, and they generally cost one eight the cost of a commercial wind generator. A good set of plans will spare you the high commercial costs and you’ll have a system that you can easily maintain. You won’t have to pay maintenance to upkeep your windmill. You’ll have first hand knowledge of how your wind generator operates.
