There's a pretty wild dynamic going on here with all these coils and magnets...
I can't say for the rest of the guys, but I for one am now thoroughly confused as to which way is up for all of this.
Your stator arrangement (individual coil polarities) may either be dead on or dead wrong, depending on how your magnets are set up.
Seems to me as though the output is still kinda low. Granted, I'm arm-chairing it here, but even with shorts aside, the entire thing should be putting out more than it does at a given RPM.
The coil diagram is a good start, but how do the magnets play into this?
It looks (from the drawing, if taken verbatim) that you have every other coil in a phase (color), out of phase with the next coil in line for that phase, within each stator. Forget for a moment that there are 3 stators; look at it as if even just one were present. Something seems off to me.
There's nothing wrong with that, provided the magnets for that phase angle are pointing in the opposing directions, so that the EMF is electrically additive, and not negating.
To see what I'm talking about, reduce it (in your mind) to a single phase, single stator, with 4 magnets (just on one side of the stator, on a single rotor, for simplification). If configured for the stator as drawn, the magnets would be at 90 degrees to each other, every other magnet flipped N-S-N-S.
That's all fine and good, until you need to add the other 8 magnets to the rotor. Then you end up with N-S-N-N-S-N-N-S-N-N-S-N (I think?). Not conducive to nice smooth sine waves at the output.
I may be so far off on what I am seeing that this particular piece of my input may be of no use to you whatsoever.
But, if not, there's no surprise that the output is very small.
Anybody else seeing this? Or am I really missing something?
