Pete,
It is built for 48v.
Glenn had for a 10 turn coil test 1.63v at 95rpm, 1.72v at 100rpm, 2.28v at 133rpm.
I took the 100rpm = 1.72v x 10 to give 100 turns = 17.2v x 3 coils in series = 51.6v.
If you take the 95rpm = 1.63v x 10 = 16.3v x 3 coils in series = 48.9v
Cut-in then, should be just before the 100rpm. I wanted more turns to lower the cut-in rpm further but run out of space to the 12mm threaded rod holding the 2 plates.
