How Does a Generator Work

How does a generator work Overview

Electrical generators are the perfect examples of the standalone machines used to provide electric power where the local grids are unavailable.

How Does a Generator Work

Most of the companies use industrial generators to provide backup power facilities to the business or the homes if they run out of power.

Generators can be used as the primary energy source in places where there is no provision of electricity or accessing it is not easy, like farming, mining, or the development of construction activities.

Parts of a Generator

A standard generator has nine parts. These parts usually play a crucial role in getting the power to the points that they are needed most. The following are the parts of the generator.


Engines act as the leading supplier of energy to the generator. The power provided by the machine determines the amount of electricity the generator can provide.


This is a part of the generator facilitating the conversion of mechanical energy to electrical energy. It is also known as greenhead.

It has the moving and the stationary parts that cooperate to produce electromagnetic fields and the movement of electrons generating electricity.

Fuel System

The fuel in the generator allows it to produce the amount of energy required. It includes the fuel pump, fuel tank, pump that connects the tank and the engine, and the return pipe. Fuel filter that removes the debris before it moves to the engine. In addition, an injector forces the fuel into the combustion chamber.

Voltage Regulator

The regulator assists the voltage of the electricity produced. It facilitates the conversion of the electricity from AC to DC while necessary.

Exhaust and Cooling Systems

The section cooling ensures that the generator does not overheat as it usually creates a lot of heat. Exhaust removes and directs the formed fumes in the process of the operation.

Lubrication System

They are small and move inside the generator. They need frequent lubrication to facilitate smooth operation minimizing the chances of wear and tear. The process needs regular check out at least after every eight hours of the procedure.

Battery Charger

They are used to start up the generator. A fully automatic device ensures that the battery is ready to go when needed. It supplies it with a constant low level of voltage.

Control Panel

This section controls all aspects of the generator, from the startup process and the running speed to the outputs. The current units sense the drip of the power dips or go out and can shut or start the generator automatically.

Mainframe or Assembly

This is the main body of the generator. We usually see the section. It is the structure holding it in the proper place.


A generator does not generate electricity. They usually convert chemical or mechanical energy into electric energy.

How Does a Generator Work

The process is achieved by capturing the power that is in motion, thus turning it into electrical energy as they force the electrons from the external sources through an electrical circuit.

Therefore, we can confidently conclude that generators are the electrical motor that works in the reverse direction.
