vertical wind turbines Frequently Asked Questions
Is there a linear relationship between rotations going into a DC generator and voltage coming out?
I'm building a small vertical axis wind turbine for a school project. I wasn't getting the voltage I needed with wind from the fan I had, so I decreased the radius to increase the rotational velocity. When I halved the radius (and doubled the RPMs), the voltage more than quadrupled. Is this an accurate relationship? Or should the relationship be linear and some other factor accounts for the increase in voltage?
Generators are usually wound to be linear over their usual operating range. When running slower than that the voltage will increase with speed but with no guarantee of linearity.
Where can i buy a horizontal and vertical wind turbine that produce electricity?
Hey ST, I'm surprised nobody has responded to this yet. Actually, there are lots of places that manufacture and sell horizontal wind turbines, but very few vertical. The reason is the vertical units are horribly inefficient. Despite what you may have heard or seen, or people have said about them, they are handy for little water pumps in the garden, or to run a few small LED lights, but even a large one will never run anything of significance.
If you are really in the market for a wind turbine, my best suggestion is first to get a subscription to Home Power Magazine. It is inexpensive, they run articles on lots of things to do with making your own energy, including wind turbines. About every third issue or so they will pick one item, like wind turbines, and compare all the different commercially available ones with all the ratings, power curves, prices and so on, so you can really compare them. Then most of the vendors run advertisements in the magazine as well. We started subscribing 12 years ago, today our home is completely powered by the wind and sun. If you subscribe, you will have access to the archived articles on their website, and you can look back at the issues that rate all the different wind turbines as soon as your subscription is started. There are some other places to get info, I will list some below. Good luck, and take care, Rudydoo
