This information will help you so much in learning the actual concept of it. If you are eager to know about it then we shall start it without losing any time.

What Is An Electric Generator?

An electric generator is a device which produces the electricity by converting mechanical form of energy into the type of electric energy. The electric generator works on the principle called Electromagnetic Induction. must be also a question This mechanism of electric generator helps us to create the electricity. We can use the electricity for various purposes that come out of an electric generator. We can store or directly use it for our purposes. However, the electric generator is a machinethat is made up of different parts. So before going to the parts of it let us study the mechanism of an electric generator. Let us see how an electric generator works and create electricity.

How Does An Electric Generator Work?

As we read the electric generator simply converts mechanical energy into electricity. But this method of converting electrical energy is a mechanism. In this process, the electrical generator mechanical energy provided to the electric generator helps to move the electric charges. These electrical charges are present in the wire winded in the electric circuit located externally. This process of conversion is called Electromagnetic induction. You must be thinking what is this electromagnetic induction.  So to understand it please read carefully further. So here is a piece of short but very informative information that you must know.

Invention Of An Electric Generator

The invention of an electric generator was done by Michael Faraday. In the year 1831 to 1832, Michael Faraday discovered the electrical charge flowing property. He came to know that the electric charge flow can be induced if the use of a moving electric conductor is done. For example, if a magnetic field applied around a wire helps to flow electric charges in it, this happens because of the difference in the voltage created between two ends of the wire or electric conductor. Hence, this discovery by Michael Faraday was known as Electromagnetic induction. It is the principle on which nowadays electric generators have.

Now let us move further and know about what are the main components of the electric generator.

What Are The Parts Of The Electric Generator?

You must be thinking that which parts of an electric generator are connected to form a such big machine. These are the following parts of the Electric generator.

  • Engine
  • Alternator
  • Fuel System
  • Voltage Regulator
  • Cooling and Exhaust Systems
  • Lubrication System
  • Battery Charger
  • Control Panel
  • Main Assembly / Frame

How To Build An Electric Generator?

To build an electrical generator you will need to understand the main components of it in detail. We have described them as follows:

  • Engine

The engine is the main component of an electric generator. It helps in supplying energy to the generator. It is the main source of mechanical energy. There are many different engines depending upon their power. It helps us in determining the amount of electricity that can be produced and created from it.

  • Alternator

The alternator is the part in the generator which helps in converting the mechanical energy into electrical energy. It is also known as genhead.  In the alternator, you will see moving as well as stationary parts. These parts in combination work for creating an electromagnetic field. The movement of the electrons occurs due to this part which also helps in generating electricity.

  • Fuel System

For producing the energy the fuel system is required, as it helped in generating the electricity and as well as the source for the external required energy. In the fuel system, there is a pump, tank, and pipe which are connected to the engine. There is a filter that cleans the fuel and transfers pure fuel to the engine with the help of a fuel injector. This assembly delivers the fuel into a combustion chamber.

  • Voltage Regulator

While generating the electricity to control the voltage properly there is a Voltage regulator located in the electric generator. It is not only used for regulating the power of the electric current but it is also helpful in converting electricity from AC to DC.

  • Cooling and Exhaust Systems

The electric generators produce a large amount of heat and it must be stopped. To stop such a thing you will need a cooling system which will help in preventing the machine to heat. However cooling is not sufficient so to increase the efficiency of the cooling system, there is the use of an exhaust system. This system is used for removing the fumes and heat out of the generator.

  • Lubrication System

This is a big device in which several parts which has more movement. So to avoid friction the generator also has a lubricating system inside. This lubricating system will allow the engine to work smoothly. The friction will reduce and the parts will not get damaged. However, you need to check the level of the lubrication regularly daily.

  • Battery Charger

For starting up an electric generator the batteries are used. The battery charger is an automatic part of the electric generator which keeps the battery maintain so that it will work on time when necessary. The battery charger provides a continuous low-level voltage to the battery and keeps it ready for starting the generator at any time.

  • Control Panel

In an electric generator, you will see a control panel. This is a part of it that helps in starting the generator, setting the running speeds, output types, etc. The control panel allows you to control the electric generator so you can use it properly. Nowadays the control panels can sense the power dipping and power cuts. It can automatically start up and shut down the generator on its own.

  • Frame

The last part of an electric generator is the frame or the assembly of the electric generator. This part of the generator should be strong as the generators are heavy devices and they work on high power. It has a powerful engine which creates a lot of sound and noise. So the electric generator should have a durable frame.

Building Of Electric Generator

The steps to build a small electric generator are here. In the following, you will know how to build an electric generator in basic.

  1. You will require a rotating axle or stationary bicycle, wire loop coil, magnets, battery.
  2. Now use the rotating axle or a stationary bicycle which will act as an energy source.
  3. Get the wire loop coil, make sure that the coil has two ends of wire opened.
  4. Now connect this wire loop to the bicycle axle properly.
  5. Make use of strong magnets near the loop and confirm that loop can move freely.
  6. Attach the axle to the battery.
  7. Sit on the bicycle and start to pedal.
  8. The electricity will start to produce.

To know more in detail about electric generators you should not miss the important information that we have given in below. This is completely related tohow does an electric generator works basically. So let us study what is that important thing which is connected in an electric generator.

Which Parts Of An Electric Generator Are Connected?

In the electrical generator as the magnetic field is an important aspect that helps in creating an electric current. But do you know how is this possible?Let me tell you about it, You will understand it easily by knowing about it in the following.

In an electric generator,some parts help to produce electric energy with the help of a magnetic field. Following are the parts of an electric generator that are connected. Below we will explain it.

  • Two Brushes
  • Two Slip Rings
  • Axle And The Coil (Armature)
  • Commutator And The Coil

In an electric generator, the coil rotates inside of a charged magnetic field. This helps in producing the electric current out of this mechanism. The rotating process of the coil in a magnetic field is called Armature. There is also a commutator that has a cylindrical shape in this setup. The commutator rotates with the armature as it is linked with it and has a connection with the armature.

The coil is connected with the slips rings. They maintain the electric contact properly with the brushes. However, the commutator also connects the coil armature to the external circuit with brushes. Hence the role of the slip rings and brushes is major in anelectric generator to produce electricity.
