three phase (none / 0) (#16)

If this is Mr. Piggot, then I'm honored that you stopped by to join in the discussion. In any case, we're happy to have you.

Personnally, I hope to make a three phase mill next year, and am fiddling with a single phase right now just to play with.

No question, three phase is more efficient, and gives you the star/delta option to better match the alternator to the avg. wind speed.

Best Regards,

troy

Thanks for the welcome Troy. There's a lot of interesting stuff on this board. To be honest I have done very little work with single phase, and I found it vibrated quite badly. The other thing that bothers me about single phase is that it should only have wires in certain positions, spaced at the same pitch as the magnets. Wires in other places produce very little power in that particular circuit (phase) but could be useful if connected to a different phase. So it seems like a waste to only be using the flux of the passsing magnets at certain times and at certain positions.
