Frequent questions

An electrical generator is a device designed to convert mechanical energy into electrical energy, used mainly in business, industrial or domestic environments. 

They work on the principle of electromagnetic induction: an engine fueled by fuel such as diesel or gasoline rotates a rotor within a magnetic field in the alternator, which generates electricity. This electricity is then used to power multiple electrical devices and systems in commercial environments, such as offices, factories, hospitals, or for events such as concerts or trade shows. See More.

Electric generators work on the principle of electromagnetic induction. They are made up of a set of key components: a rotor, a stator and a magnetic field

The rotor is a coil of wire that is connected to a mechanical power source, such as an internal combustion engine or wind turbine. When the rotor rotates, a relative motion is generated between the coil conductors and the magnetic field. This creates an electromotive force (EMF) in the coil according to Faraday's law. 

The stator, on the other hand, is a fixed structure that contains a set of coils of wire which are known as windings. These windings are strategically arranged around the rotor and are connected to the output terminals of the generator. 

When the EMF is induced in the rotor, an electric current is generated in the stator windings. This electrical current is transferred through the output terminals and can be used to power electrical devices and appliances. If you want to know more click here.

The most efficient electricity generators on the market today are inverter and diesel-powered models. Inverter generators They stand out for their ability to adjust energy production to exact demand, significantly reducing fuel consumption and improving energy efficiency. On the other hand, diesel fuel powered generators are known for their durability and ability to operate efficiently under heavy loads, making them ideal for long-lasting commercial and industrial applications. The combination of inverter technology with diesel engines represents maximum efficiency for electric generators. See More.

Electric generators consist of several main parts that work together to convert mechanical energy into electrical energy. These are the fundamental parts of an electric generator:

  1. Rotor: Also known as the rotating component, the rotor consists of a shaft and a set of coils of wire. It rotates inside the stator and is responsible for creating the relative motion between the coils and the magnetic field to generate the electric current.
  2. Stator: It is the stationary part of the generator and consists of a laminated iron core and coils of wire. The stator windings are arranged around the rotor and are responsible for capturing the electric current induced by the relative movement.
  3. Magnetic field: It is created by using magnets or electromagnets located in the stator. The magnetic field interacts with the rotor coils and is essential for the induction of electric current.
  4. Electric connections: Generators have terminals or connection points where electrical devices can be connected to receive the generated power. These connections are linked to the stator windings.
  5. Case: It is the external structure of the generator that protects and houses the internal parts. In addition, it provides isolation and security for users.

These are the basic parts of an electrical generator, but it is important to note that there may be other additional components depending on the type and specific configuration of the generator. Check this entry Blog.

There are two features that guarantee that your generator will use less fuel, the first is that it is an inverter, and the second is that it is a diesel-powered generator.

Inverter generators They are known for their fuel efficiency. They use a variable speed motor that automatically adjusts engine speed to produce only the electricity needed, resulting in lower fuel consumption compared to conventional generators.

Diesel powered generators They generally use less fuel compared to those that run on gasoline. This is due to the greater energy efficiency of diesel as a fuel, which provides a greater amount of energy per liter. Additionally, diesel engines typically have a longer lifespan and are more durable, making them suitable for intensive and prolonged use. For these reasons, if you are looking for a generator that maximizes fuel efficiency, especially for high demand or continuous use applications, diesel generators are generally the most recommended option.

If the generator is inverter and at the same time works with Diesel, this represents a maximization of efficiency and fuel savings. See More

To select the right type of generator for a home, it is important to consider factors such as the size of the home, the number and type of appliances you want to power, and whether you prefer a portable generator or a stationary one. Portable generators are suitable for temporary or smaller-scale needs, while stationary generators are more suitable for continuous use and can power the entire house. Look at this entrance.

Before purchasing an electric generator, it is important to consider:

Power Capacity: Determine the watts needed for the devices you plan to power.
Fuel type: Choose between gasoline, diesel, natural gas or propane, depending on availability and preference.
Portability: Decide between a portable or stationary model depending on the need for mobility.
Noise level: Consider the noise level, especially in residential areas or for recreational use.
Additional characteristics: Such as electric start, fuel indicators, overload protection, among others. See More

When purchasing an electric generator, consider:

Energy Needs: Calculate the total watts required.
Generator Type: Choose between inverter, portable, or stationary depending on your needs.
Efficiency and Fuel Type: Determine preferred fuel type and look for fuel-efficient options.
Security Features: Look for features like low oil automatic shut-off, overload protection, and good insulation.
Budget and Guarantee: Keep your budget in mind and look for guarantees or after-sales services. Look at this entry Blog.
