What is the frequency produced by a 4-pole generator rotating at 1800 r/min?
To solve, apply the formula of the frequency for ac generator which is:
f - frequency of generator
N - number of revolutions per minute
S - number of poles
So, plug-in P=4 and N=1800 to the formula.
Hence, the frequency of 4-pole generator with a speed of 1800 rev/min is 60 Hz.
