What is an electric generator?
The electric generator is one of the most demanded devices on the market because of its ability to convert mechanical energy into electrical energy, but have you ever wondered how it works?

The key to the operation of the electric generator is in the so-called Faraday Law , which states, verbatim, that in order for an electric current to be generated there must be a movement between the conductor and the magnetic field since “the voltage induced in a closed circuit is directly proportional to the speed with which the magnetic flux that crosses any surface with the circuit as an edge changes over time ”.

In other words, the electric generator uses a magnetic field to generate a movement of electrons and produce electrical energy.

Exactly, when assembling the conductive coil to a continuous electric current, a change in the magnetic field flux is achieved, which interacts with the poles of the magnet and causes the coil to rotate on itself producing a psychomotor force capable of transforming into electrical energy .

This is because if an external circuit is connected to the coil terminals, this voltage will generate current through this circuit, which will be energy that will be transmitted to the load. Therefore, the mechanical energy that rotates the coil is converted into electrical energy

What is an electric generator inverter?

An inverter generator is one that can filter the sine wave to generate a pure wave with the magnitude and frequency that is needed and thus overcome the negative and positive elements. In other words, this technology allows the regulator to emit a stable electric current that neutralizes the vulnerability of your electrical appliances and appliances to scattered sine waves and of poor quality.

What is a single phase electric generator?

Also known in English as a single-phase generator, a single-phase generator is a sinusoidal generator for the production, distribution and consumption of electrical energy consisting of two terminals and a single alternating current that conducts a single 110-volt line.

What is a three phase electric generator?

On the other hand, a three-phase generator , known in English as three-phase generator,  is a sinus generator made up of three single-phase alternating currents connected in a triangle or a star. One of the great advantages of three-phase generators is that they have a higher performance of the receivers, especially in motors

How do electric generators work and what components are involved in their operation?
An electric generator consists of four indispensable parts. The armature or winding, which in turn is made up of spirals that rotate with their tips cut the induction lines of the magnetic field and introduce current and maintain it while the spirals are in motion. The group completes the brushes, which are responsible for externalizing the generated current, and the collector, which are welded rings.

To operate, the current that this generator gives to the outside through the brushes, reverses its direction every time the armature or winding turns. Each time this happens, the intensity increases from zero to a certain value, decreases to zero again and thus changes its value in the same way.

Parts of an Electric Generator

The electric generator is composed of a series of elements through which it manages to operate correctly.
  • Motor - It is the most important part because it is the source of the initial mechanical force.
  • Alternator - It is responsible for the production of electrical output and mechanical input in electric generators.
In turn, alternator is formed by:
  • Stator : The fixed outside part of the machine where the induced coils that produce the electric current are located. The stator is placed on a metal housing that supports it.
  • Rotor : This is the moving component that rotates inside the stator and that causes the inductive magnetic field generated by the induced winding.
  • Fuel system - Depending on the electric generator model, it will have a capacity or another, although the average is a range of 6 to 8 hours.
  • Voltage regulator -  This element transforms the AC voltage into DC.
  • Cooling and exhaust systems - It is responsible for monitoring that the electric generator does not overheat and is used as a route to the outside.
  • Lubrication systems - Lubrication guarantees the fluidity and durability of the activities of the electric generator.
