new generator setup

[Drevtoobe]

You have a design issue to resolve with the big pick-up coils and the top neo rotor. The big coils will always be "seeing" the magnetic flux from two or three of your neos at the same time, kind of like an averaging function. You don't want that, you are looking for changes in flux, big flux on-offs as the rotor turns. The simple solution is to remove four out of your eight neos.

Plan B would be to mount much smaller coil(s) about the diameter of the individual neos. The neos should be NSNS.

[Drevtoobe]

If you were to remove four of the eight neos then the pattern as you go around the rotor should be N N _ _ SS _ _. That will make the rotor look like one single big spinning magnet relative to the pick-up coils.

If you go with plan B then the magnet arrangement should be NSNSNSNS. This pattern will result in each magnet's flux reinforcing its two neighbours fluxes. The net result is that each magnet in the rotor will output more flux as compared to an all N or all S configuration.

I cant wait you do this experiment

Welcome back :) Back for your Bedini fix ROFL....

I tell new comers when they ask me what to do next to RUN RUN while you still can. :-)

You might want to look at wind generator setups to get an idea of ways to wind your coils.. Another idea I want to test is to take the output of the coil and put it into a transformer and then rectify the output, someone else has had great sucess with that. All my toys are packed up... MOVING!! sigh, I need another fix soon :)

thanks. It's good to be back. And yes I've downloaded a ton of great stuff on wind generators. I especially like to solid wood one. I'm sure you've seen it. Good luck on your move. GAWD i hate moving...ugggg

then if you want, take a look at "lenzless" generators, they speeed up underload - the more you want the more it gives =D. rectorfie apart. the voltage will be low but the amperage is higher and less prone to slow down.

[mcorrade]

I've seen them and there very cool. Thanks

VDR's only work properly on a bipolar setup (IE North and South poles alternate past a coil)

VDR's are quite simple, 2 diodes, 2 capacitors... I've had a couple of people ask about them so i'm gonna do a laymans video tomarrow on how to construct one...

> rectify each coil seperatly?

You can only connect coils directly if they are in phase with the magnets on your rotor...

Also, using a standard bridge rectifier is very in-efficient, look up voltage doubling rectifier in a search engine...

Also, the gauge of wire your using is quite thick, 25 gauge I think you said... I' using 27SWG and i'm getting low voltages... i'm considering using smaller wire say 30-35 SWG... so that i can get more turns closer to the magnets thus increasing voltage...

[mcorrade]

thanks a million for the rectifier tip. I was going to use 24 SWG because I'm told the thinner the wire the higher the voltage and the thicker the wire the higher the amps. So I thought 24 would be a good in between no?

[comwarrior69]

it does depend on setup and what magnetic field you've got and the speed at which the field alternates...

best thing you could do is to try one coil and see the results... then wind another and see the results...

Their is proberbly a formula for working it out... but i can never find one... lol

[mcorrade]

thanks again. I want to ask you about the voltage doubling rectifier. I've been researching it and it appears to not be a single component but a circuit. I'm net really good at reading these schematics and was wondering if you can help me out here?

thanks,
