Homework Statement

What are the effects of changing the speed of alternator?
(elctrical synchronus generator)

Homework 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

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?
