Answer / kj

Yes
By replacing the field winding with permanent magnets. The
problem with doing this is that the output voltage is
controlled only by the speed of the alternator. This means
that at constant speed (frequency)the voltage will fall as
the load is increased. If the voltage must be constant the
speed must be increased with load. So the frequency will
not be constant.

what are the effects when a salient pole alternator is run at high speed like 3000 r.p.m?
