What Is An Alternator: BC Parts Glossary

If you are at all familiar with pop culture, then you may have heard the phrase “It’s your alternator” in a film or two. But do you know exactly what is it and how it works?

The alternator is a generator that transforms mechanical energy into electrical energy (this is referred to as an alternating current). Using a rotating magnetic field and stationary armature, it is driven by the internal combustion engine of the vehicle.

Dating back to the 1830s, these centralized power stations are responsible for the regulation and stability of electrical systems (such as the windshield wipers, radio, headlights, and more) while the motor is running. They are also used to keep the battery charged.

Approximately the size of a coconut, you will find this small piece of machinery with a running belt attached to it located on the front section of the engine. There are three main parts including the voltage regulator, diode rectifier, and cooling fan. The first oversees the output of power, the second is a converter, and the third prevents the component from overheating.
