How does a power generator work?

A power generator is, as its name implies, a device capable of generating energy. This is responsible for converting any type of energy (e.g. chemical, mechanical, etc.) into electrical energy.

Energy is a fundamental resource and nowadays we are completely dependent on it to be able to do the most common tasks of everyday life, to get work, to keep the equipment running, and to make the world go round.

To overcome as energy failures, since the electrical systems are fallible, the generators are used to minimize these faults. In this way, it ensures a continuous supply of energy to supply as needs.

And where is the power generator usually used?

It is very common to find in:

  • Hospitals
  • Hotels
  • Large Industries / Companies
  • Events
  • In some houses


So how does a power generator work?

To start up, the direct current generator is dependent on electromagnetic induction, capable of transforming / converting it into electrical energy. The dynamo is one of the most well-known types of energy generators and converts the existing mechanical energy into the rotation of the shaft. This causes the magnetic field strength to oscillate, leading to voltage induction at the terminals it has. So, when they are subjected to loads it leads to the circulation of energy.

There are several types of power generators available, and you can find different models and different powers, so that you can adjust to your reality.

To convert mechanical energy into electrical energy you can choose between these types of generators, namely:

  • Asynchronous (or Inductive) Generators;
  • Synchronous Generators;
  • Continuous Current Generators.


It should be noted that electric motors are like generators, yet they convert electrical energy into mechanical energy. There are also ways to convert chemical energy into electrical energy, for example through batteries. Regarding the conversion of solar energy into electricity, this is achieved using photovoltaic generators.

Now that you know how the energy generator works and how important it is, you just should choose the most convenient solution for you.
