I've seen this article used to build one before, and it actually turned out pretty decent.

This is part of a whole set of articles I will be posting.

    That's quite informative. :)
    A friend of mine runs alternative power to his property. Water and solar, not wind though but still interesting. :thumbsup:

    The whole construction looked idiot proof until I hit the schematic.

    I take it you didn't like the voltage brah. :D

    Cool idea. and we need Katzenklavier to do this project due to the high voltage etc.

    That is actually a pretty simple circuit. It takes the 8 volts from the LM7808 and compares it to the voltage on the batteries. When the voltage on the batteries reaches a certain point (that point determined by the two potentiometers) it kills the power to them via the relay. That circuit is overcomplicated though, all one needs is a schmitt trigger.

    I might build one, I have had an old washing machine motor sitting around here for the past 3 years that is wired for 3 phase ac and generates around 48 v when spun by hand, I got the output up to 300v when I used a drill to spin it when I tested it after removing it from the washer. According to what i have read about the particular model of motor is that they can produce around 1kW of power, i just need a way of bringing the voltage down low enough to charge a couple of 12 v batteries.

    In order to avoid huge losses I'd say you'll have to design a buck converter for the task.

    The mate that has alt power uses these near the river at the back of his property. They apparently work well. :thumbsup:

    I was thinking i would. For some reason i was thinking along the lines of using a transformer but that would just end up wasting energy

    They will give a decent belting if you happen to be holding on to the output while you give it a spin, or make a CFL flicker on

    He had six of them, not sure how many he has now? Water wheels were f-glass coated ply. He said they have enough punch in them to do the job. :thumbsup:

    This is a great article. However I can't just add content that belongs to another site.

    Moved back to Green Planet.

    Could the text content be reworded to make them original? Just curious. :)

    That's a fancy motor daktologist. BTW, fairchild gives out free silicon again...

    And they weren't meant to be "guides" they are pieces to a larger guide I am writing. They just need to be there for me to link to later. ;)

    Guide prefix removed.

    Why does the content have to be original? If the information is important and well-written, give the author credit, and post it.

    It doesn't have to be original, but one link does not warrant a guide prefix. At least make the effort to transfer some of the content over to the original post. If you wish to discuss this further, make a thread in H&S.

    Oh yeah I definitely agree with the guide needing to be typed out at least sorry for the confusion. I see how my original post could have been a cause of confusion.

    Anyone know where to get cheap magnets? I found some Sumerian cobalt magnets, and it looks like you can get twice as much surface area for the same price as half of the neodymium ones. Would it be better to have more surface area or just to have a stronger magnet? Is coating the coils in resin for insulation or just so it will rotate smoother? I don't understand why the electrons would be leaving copper wire and intense magnetic fields just to float around in the atmosphere.

    Also, in some of these designs, they have two rotors with magnets and the coils inbetween, like a big sandwich. Is it necessary to have both of the magnet boards in rotation? What would happen if you the back one sit still and only had the front one rotate?

    Sumerian magnets are good, but despite their similarity I think Akkadian magnets are marginally superior.
