An electric generator is typically a machine which converts any type of energy, it can be chemical, mechanical or light energy to electricity or electrical form of energy. An electrical generator is all that a device capable of maintaining an electric potential difference between the two points, called centers or terminals. Electric power generators are machines which are designed to transform mechanical energy into electrical one. There are two types of electric generators which include:

  • DC generators

DC generators produce direct power. These generators produce electrical power, based on the fundamental principle of Faraday’s law of electromagnetic induction. According to this law, when a conductor moves in the magnetic field, it cuts magnetic lines of force, due to which an emf is induced in the conductor. You can check out the predator 4000 generator reviews, which is one the best Dc generator for your home.

There are three classifications under DC generators:

Permanent magnets:

In the magnetic circuit, when the flux is established with the help of permanent magnets then it is known as Permanent DC generators. It generates very low power. They are used in small applications and are rarely used in industrial applications.

 Separately excited DC generators:

These generators which are influenced by an external DC source and are energized.

Self-excited DC generators:

These generators get energized automatically by themselves. They get residual magnetic flux, by which it is available near the poles. When the armature is rotated some emf is generally induced when this sort of current flows through this field coil, the pole flux gets strengthen and it will produce more armature emf.

  • AC generators

This is a type of generator which produces, an electromotive force by changing the number of magnetic flux line, which is passing through the Wire Coil.

There are two types of ac generators:

Asynchronous generators:

These generators are also known as induction generators, which are motor driven which does not increase the speed of the of the full load slip till the full load slip. Thus, the asynchronous generators require various additional items before it produces power and also requires a leading VAR’s for excitation. The induction generators do not require any special Dc excitation, regular controllers, frequency controllers or governors.

Synchronous generators:

Synchronous generators are used to as they provide us with precise control of voltage, frequency, VAR’s AND WATTs. This control is achieved through the use of voltage regulators and governors. This generator consists of revolving DC field, which is commonly known as rotors. Thus, the frequency of the voltage depends upon the speed of the rotor and number of field poles.


Electric generators play a very vital role for your household or business works. Check out the above-mentioned types of generators, and buy one, which will serve you the best full filling all your requirements.
