Question
In parts of South America, the frequency of the power system is $50 \mathrm{~Hz}$. If a three-phase, eight-pole synchronous machine is used as a generator, determine the speed of the rotor.
Step 1
The synchronous speed (Ns) of a synchronous machine can be calculated using the formula: \[ N_s = \frac{120 \times f}{P} \] where \(N_s\) is the synchronous speed in revolutions per minute (RPM), \(f\) is the frequency in hertz (Hz), and \(P\) is the number of Show more…
