Here’s a step-by-step guide to building your own wind generator made out of basic materials like PVC pipe and sheet metal. Author Mike Davis explains how he started on this project:
I started by Googling for information on home-built wind turbines. There are a lot of them out there in an amazing variety of designs and complexities. All of them had five things in common though:
1. A generator
3. A mounting that keeps it turned into the wind
4. A tower to get it up into the wind
5. Batteries and an electronic control system
I reduced the project to just five little systems. If attacked one at a time, the project didn’t seem too terribly difficult. I decided to start with the generator. My online research showed that a lot of people were building their own generators. That seemed a bit too complicated, at least for a first effort. Others were using surplus permanent magnet DC motors as generators in their projects. This looked like a simpler way to go. So I began looking into what motors were best for the job.
