Electric generators: types and most common uses

Electric generators are perfect for obtaining electrical energy in situations where you need to work in areas with no electricity. They also resolve inconveniences such as power outages, as they allow all equipment to continue to be used.


There are various types of electrical generators, such as: portable, inverter, solar, standby, etc. Each one has specific characteristics, which are adapted to a specific situation and allow you to get the most out of the equipment.


In today's post we’ll tell you what they are, the most common types and their different uses, and the advantages you’ll get from using them.


Let’s begin!

What are electrical generators?

Electric generators are indispensable devices, providing a constant and reliable supply of electricity.

An electrical generator converts mechanical energy into electrical energy, but how does it work?


Its operation follows the principles of electromagnetic induction. The generator consists of a rotor, which rotates within a magnetic field generated by a stator. As a consequence, a rotary motion of the rotor occurs, which generates an electric current.


They are essential in situations where a source of electrical power is needed, either as a backup during power outages, in remote areas without access to the grid or in industrial applications.


"The electric generator is essential in the mass production of electricity in power plants, as well as in smaller applications, such as portable generators."

Types of electrical generators



In the following, we will explain the most common types of electric generators and their characteristics:


-Portable generators

As their name suggests, they are ideal for use and transport anywhere, as they are lightweight, come in compact designs and usually have a trolley or wheels.


They are also ideal for a variety of environments where there is no access to the local electricity grid. These can include, for example, construction sites with no electrical facilities.


Its portability and versatility are a great advantage, and it provides a totally reliable power source. Depending on the model, they can use petrol, diesel, gas or sunlight for proper operation.


-Petrol generators

These are some of the most popular generators, as they are widely distributed and offer low fuel consumption costs.


Portable models are the most commonly used, although a wide range of sizes and prices can be found.


They are perfect to meet the needs of a business, home or any area/space away from the city.


It should be noted that they are quite fuel-consuming and are not suitable for indoor use, as the combustion of petrol releases toxic gases. If you choose this option, be sure to place it in a ventilated area.


Despite this, they are known for their ease of start-up, portability and ease of maintenance.


-Diesel generators

These generators are larger, so they cannot be moved as easily. They are also more expensive and require more maintenance than petrol generators. 


That said, they are more fuel efficient and despite needing to be serviced periodically, this may be done less frequently than with other models.


These generators are known for their efficiency, durability and load capacity. They are also designed to withstand adversity, heavy loads and intensive use, and can provide a reliable power source in industrial and/or commercial environments.

Other types of generators

-Emergency generators

They are usually large machines that provide electricity and a stable supply for many hours.


Its main function is to provide electricity when power outages occur. The equipment switches on automatically and avoids the inconvenience of disconnection from the mains.


The price of these generators is higher and they require more maintenance to ensure proper operation. Even so, they are very useful in emergency situations where the electrical service is affected.


The only drawback is that such generators cannot be transported due to their size and weight. They are normally installed at the location where they will be used and will remain there throughout their service lives.


-Inverter generators

These generators can be portable or standby. They provide stable power during operation, create direct current and convert it into alternating current.


Alternating current is of great benefit, as it is more powerful than direct current. It also allows for safe changes in voltage and current flow.


This type of generator is recommended for equipment commonly used in businesses and homes, such as modern electrical appliances, televisions, computers, etc. They also produce little noise — a great advantage compared to other models — and prevent damage due to voltage fluctuations.


If you know the specific use to which you intend to put your electric generator, you will know which model is best suited to your needs.

As you will have seen, there are several options for electric generators. 

When choosing one, you should take into account some points such as: the amount of energy you will need, the portability of these depending on the place of installation, and the climate of the region.


Once you have analysed these points, you will be able to choose the perfect generator that meets all your needs.
