calculating voltage of test coil | 3 comments (3 topical)
Re: calculating voltage of test coil (3.00 / 0) (#3)

got the air gap smaller - quite small actually, probably too small for the finished stator!  but, up to 4.5v at 300rpm.

i flipped the magnet rotor over so the magnets point towards the floor, so i could set the coil on some wood blocks to position it.  does anything behind the coil besides air affect anything?  flux return etc?  if so, i wouldn't think it would be too drastic.
