Generator End Basics

When selecting a generator, knowing about the specifications of the generator end, or alternator, is a crucial component. A generator end is the portion of the generator which produces electricity. A quality generator end is essential to a quality generator, as without it the rest of the generator is useless.

A modern generator that is typically used today relies on the principle of electromagnetic induction, discovered in 1831 by Michael Faraday. This principle states that electrical charges can be created by using a moving electrical conductor within a magnetic field.

A generator works by using fuel, typically either gasoline or diesel, to power a motor. This is the mechanical input of the machine. The engine then powers a moving component that produces a magnetic field. This component is known as the rotor. The chamber also contains a stationary element, which are electrical conductors in the form of coils. This portion of the generator is the generator end, otherwise known as the alternator.

The magnetic field can be produced in three different ways: induction, permanent magnets, or an exciter. Induction produces electricity when the rotor, spins faster than the synchronous speed. Permanent magnet generators work by driving magnets through the coils to produce electricity. An exciter generates energy by using slip rings and brushes.

This magnetic field is where the electricity is created. The magnets produce the field through movement of the rotor, which is then captured in the coils. The energy can then be extracted through the regulator and used as AC power.

If the generator end is not working correctly, then the generator cannot create electricity. Many people are under the assumption that the motor itself generates power. Although the engine does play a large part in the creation of electricity, the motor by itself is not the complete story. The generator end is a significant part of the generator, and without it, the generator is not whole.

There are several different factors to take into consideration when looking at generator ends. Generator ends can have either metal or plastic housing, and metal housing is considerably more durable. The type of bearings is also essential to consider, as ball bearings last longer and require less maintenance than needle bearings. The way that the generator end produces electricity is also important. A brush-less design requires less upkeep and delivers cleaner power than other methods, such as the exciter method.

Selecting a quality generator includes taking into account the generator end. Researching the types of alternators and deciding on which is most appropriate for your needs will help to find the perfect generator. Generators are built to last, so choosing the proper one is essential.
