The answer is because these alternators are synchronuse
generators. The philosophy of electrical synchronuse
generators is based on DC excitation in the rotor and
synchronuse vontages in stator.
However,there are some application for induction generators
such as wind generators that have AC excitation like other
induction motors.
As a reslut, if alternator is synchronuse generator it has
to have DC excitation and if alternator is induction
generator it has to have AV excitation.
