A synchronous generator with 4 poles is designed to operate at a frequency of 50 Hz. Calculate the synchronous speed of the generator. If the rotor speed decreases to 1400 RPM, what is the percentage slip?
💡 Hint: Use the synchronous speed formula and compare it with the actual rotor speed.
If a synchronous generator operates at 2,000 RPM with 6 poles and produces an EMF of 400 V, what is the frequency of the output? Also, if the flux per pole is reduced, how would that affect the EMF?
💡 Hint: Know the relation between RPM, poles, and frequency, as well as the EMF equation.
