To solve, apply the formula of the frequency for ac generator which is:

`f=(NP)/120`

where

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.

`f=(1800*4)/120`

`f=60 Hz`

Hence, the frequency of 4-pole generator with a speed of 1800 rev/min is 60 Hz.
