What Is AC Generator and Its Working Principle

What is a Generator? A generator is a machine that converts available mechanical energy into electrical energy. It works on the principle of Faraday’s Law of Electromagnetic Induction. Based on the output obtained, we classify generators as:   AC Generators or Alternators AC generator, also known as alternators, is a machine that converts mechanical energy into electrical energy. The generated electrical energy is in the form of an alternating current sinusoidal output waveform. The mechanical energy is usually supplied by steam turbines, gas turbines and combustion engines.   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 by rotating the magnetic field that contains the stationary conductor. The preferred a...

What Is the Working Principle of Alternating-Current Generator?

There are many forms of generator, but the working principle is based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is to use appropriate magnetic conductive and conductive materials to form magnetic circuits and circuits for mutual electromagnetic induction to generate electromagnetic power and achieve the purpose of energy conversion. Working principle of alternating-current generator The mechanical energy of the prime mover is converted into electrical energy output by using the principle of electromagnetic induction in which the cutting of magnetic lines of force by a wire induces electric potential. A synchronous generator consists of a stator and a rotor. The stator is the armature that emits power, and the rotor is the magnetic pole. The stator is composed of armature iron core, three-phase winding with uniform discharge, base and end cover. The rotor is usually a hidden pole type...
