1. The problem statement, all variables and given/known data What are the effects of changing the speed of alternator? (elctrical synchronus generator) 2. Relevant equations Ns=120*f/p; p-poles f-frequency Ns-synch speed E=4.44*f*phi*T phi-max flux linkage T-turns f-freq E- generated voltage 3. The attempt at a solution from the above formula, if I increase the speed of the shaft, 1)then my output frequency will increase 2)also generated voltage will increase Q1)my query is will the above action increases the power rating of the alternator? Q2)what will be the effect to alternator if do so? like will there be any coil burn issue?
