 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Just thought I'd share a fun project that I've been tinering with. Posted on OP in my diaries here... http://www.fieldlines.com/story/2006/9/5/13246/47609 |

Very clever Ed. Is it double sided? A double sided board could have another coil on the PCB back, either in phase or at 90 degree, giving a 2 phase alternator. Hey, why not go for multi layer  and really watch the manufacture price go up.
Be interrested to see how it went as a dual rotator, with the magents so close through the PCB board, the magnet flux would be very intense. I think we talked about this once before. Glenn The best time to plant a tree was twenty years ago, the second best time is right now. JAQ |

It is a multi layer layout, it has 4 layers of 9 turns or traces in series. I thought of doing a dual rotor with it to see how it faired. Putting the magnets that close together is a pretty scarry thought and would take some heavy duty jacking device to get it together or apart without creating a disaster. It might work just as well to use a blank disc behind it as the second rotor. Being that close the magnetic path is pretty short. Have Fun! Windstuff Ed |
