AC generator is a machine that converts mechanical energy into electrical energy. The AC Generator’s input supply is mechanical energy supplied by steam turbines, gas turbines and combustion engines. The output is alternating electrical power in the form of alternating voltage and current.
AC generators work on the principle of Faraday’s law of electromagnetic induction, which states that electromotive force – EMF or voltage – is generated in a current-carrying conductor that cuts a uniform magnetic field. This can either be achieved by rotating a conducting coil in a static magnetic field or rotating the magnetic field containing the stationary conductor. The preferred arrangement is to keep the coil stationary because it is easier to draw induced alternating current from a stationary armature coil than a rotating coil.
The generated EMF depends on the number of armature coil turns, magnetic field strength, and the speed of the rotating field.
The Working Principle of AC Generators is that they are frequently referred to as alternators and operate on the principle of Faraday’s Law of Electromagnetic Induction. The magnetic flux associated with the coil changes when a conductor moves in a uniform magnetic field, causing an EMF.
