Common Types of Generators and Their Uses

Common Types of Generators and Their Uses
  • Opening Intro -

    Generators have become something commonly seen in disaster-prone areas.

    However, they are not the only time people rely on generators for their homes or businesses.


Knowing the various types of generators and their uses can help you determine the right one to buy.


Portable generators like the Generac Generator allow you to have power anywhere you need it. When the electrical grid has issues, portable generators can quickly go into service. These are quick and easy forms of power used by homeowners and business owners alike.

Even drip irrigation systems in large agricultural operations can use the power of a portable generator to keep their crops growing while electricity is down.


Available as either a self-excited generator or an externally excited generator, induction generators have specific applications mostly in the commercial sector.

Windmills often use self-excited generators to convert wind power into a form of electricity that is usable. Electric locomotives, hoists, elevators and cranes use the regenerative braking applications of an externally excited generator.

While there may be other uses, these are the most common applications for induction generators.


Appliances often have an inverter generator to create AC power they need to operate. The generator takes AC powers using a rectifier to create DC power that is then inverted back to AC power.

Appliances receive the steady electrical current needed to effectively and efficiently run. The lightweight, compact generators give vehicles, ac units, recreational vehicles, boats and refrigerators the frequency and voltage necessary to operate.

Unlike the small versions used for small businesses and homeowners, industrial generators can work under harsh conditions. These rugged, robust generators range in their ability to conduct power using a three-phase or single-phase supply.

Industrial operations often customize these generators for a specific purpose. They can rely on a variety of fuel choices to provide the necessary electricity depending on their needs.

Natural gas, diesel, propane, gasoline and even kerosene are all common options for these generators. While most industrial generators are large in size, these large businesses may also use portable generators in small, hard-to-reach areas.

other valuable tips:


When the power grid fails, easily switch on a standby generator. These convenient generators allow your business or home to automatically keep the power on. Hospitals and hotels are the most common users of these generators.

They help the businesses continue operation when the power is out, but the business may only be able to rely on standby functions. For example, a hospital may limit the number of lights on when the generator is in operation.
