Calculate generator output voltage from flux, speed and winding turns.
Induced EMF is proportional to flux, frequency and turns. Because voltage rises with frequency at constant flux, a machine designed for 50 Hz produces 20 per cent more voltage at 60 Hz unless excitation is reduced. The volts-per-hertz relationship is why generator and transformer designs are frequency-specific and cannot simply be swapped between regions.
