bi,
The original rotor was taken out of the old machine a long time ago, so I can't test these new coils with that particular rotor and magnet combination. It had the six 2" magnets on it. I haven't had time to tear the machine down and put that rotor back in it, and now that all my testing is complete, I see no reason to do that. It became obvious when I tested with the small rotors using different magnets and a single coil what my problem is. I had four magnets on the rotor for each size magnet test, and I connected the single coil up to a 100 watt load.
2" x 1/4" magnets output 50.3 volts at .01 amps to the load. These were the ORIGINAL magnets that (with six of them on the machine) at the correct RPM, output 130 volts at .75 amps
3/4" x 3/4" magnets output 14.9 volts at .00 amps These are the magnets in my CURRENT rotor.
3/4' x 1" magnets output 27.8 volts at .001 amps
1" x 1" magnets output 50.3 volt at .015 amps. A bit better than the original magnets and I can put 20 of them on the rotor instead of six.
Since my current magnets only output 29% of what my original magnets output, I can safely say that changing magnets will make a SIGNIFICANT difference, and should get me back in the ballpark of where I want to be. We shall see.
