"Like everything though, it's a compromise. If you make really big holes in your coils, you'll have really great "efficiency" and pretty wave forms, but less total output than if you pack more copper in with a smaller hole size."

Troy what if everything was bigger? I mean even the armature too? What if everything was scaled up to accomidate the new hole size, so the diamitor of of the armature was bigger too, would the output increase without losing the efficiency?

I don't know, asking.
Damn it Spoc, I'm a motivator, not a DJ.
Nice job by the way.

I agree that larger rotors and stators offer some advantages like less crowding of the coils and magnets, which may provide better efficiency compared to cramming the same wire and magnets into a smaller alternator. The downside is bigger/heavier/more expensive construction. I'm still pondering the implications of the data, as far as the ideal mix of coil size vs magnet spacing. Will keep you posted on the outcome..

Best Regards,
troy

Credit where credits due, even for you. Hey here's one that may or may not already exist, shape magnets to be airodynamic, have them on the outer most tip of the windmill blades. Not too heavy but flying past a coil at high speed, 'while' it turns the hub genny too.

Just an idea I want to try but too many irons in the fire. "emagination is more important as knowledge" said the man in the funny hair.

I think some of the minds on this board should just form a mini "corporation" (with out the yuck usually associated with that word) and just pump out patents. Working alone can have benifits but a team often produces more. You could be the "The Copper Head Gang" Copperhead Inc.

Give me the word, I'll chair it, tee hee.
