Consider a 4pole generator How fast in rpm do you have to ro

Consider a 4-pole generator. How fast (in rpm) do you have to rotate the shaft to get a 60Hz wave? Use R or matlab do plot one cycle of 3-phase 60 Hz sine wave voltage (plot all 3 phases together).

Solution

N=120f/P

N=120×60/4

N=1800 rpm where

P=Number of poles=4

f=frequency in hz

N=Speed of shaft in rpm.
