Derivation of EMF Equation of Synchronous Generator or Alternator
The following is the derivation of emf equation of Synchronous Generator or Alternator. Let Φ = Flux per pole, in Wb. P = Number of poles. N = Synchronous speed in f = Frequency of induced emf in Hz. Z = Total number of conductors. Zph = Conductors per phase connected in series. Zph = Z/3 as number of phases = 3.
