..made another test coil today, 35 turns gives approx. 2,5VAC @ approx. 60rpm with an airgap of ~7mm each side of the coil. I´m not sure if the airgap affect the voltage or not..? I will narrow it down towards 2mm each side at final test. 2,5VAC x 15coils = 37,5 RMS(RootMeanSquare) volt. 37,5 x 1,414 - 1,4(rectifier loss) = 51,63volts to battery
Did I calculate it right? In case I did, it seems this coil is pretty close to what I will wind. However, I will make one testcoil later when I have the correct wire available.
