Principle Of Ac Generator

Principle Of Ac Generator. We can collect the induced emf in the loop in two different ways Let us connect slip ring with both ends of the loop We can connect a load with the loop through the brushes rest on the slip rings as shown In this case the alternating electricity produced in the loop comes the load This is an AC electric generator.

PDF fileA threephase AC generator is designed to produce threephase AC power by building more coils in the stator around the rotor The three coils are equally spaced 120 apart ° around the inside of the stator The armature coils are wired so that the generator has three separate output voltages that differ in phase by 1200 Figure 3.

Working Principle of AC Generator

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 currentcarrying 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.

What is an AC Generator Construction, Working, Types

Basically an AC generator is an electrical machine that converts mechanical energy into electrical energy in the form of Alternating Current (AC) Basic principle behind the working of an AC synchronous generator is also Faraday’s law of electrical induction somewhat similar to working of a DC generator.

Synchronous Generator – Construction and Working Principle

The AC generators or as they are also called the Alternator are one of the most essential devices of providing electrical power in several conditions in our life ACs work based on the principle of electromagnetic induction AC generators are classified into two categories induction generators and synchronous generators.
