Working Principle of Alternator
The machine which produces 3 phase power from mechanical power is called an alternator or synchronous generator. The working of an alternator is based on the principle that when the flux …
4 Advantages of Stationary Armature in Alternator
An alternator operates on the same fundamental principle of electromagnetic induction as a DC generator i.e., when the flux linking a conductor changes, an e.m.f. is induced in the conductor. Like …
