How Does The Alternator On A Car Works?

The generator is a generator of electric current in a car and the main element of the vehicle charging system. All cars with internal combustion engines, except a few hybrids, have a generator. When an engine is running, the generator charges the battery and provides additional electrical power to the vehicle's electrical systems.
The generator is screwed to the engine and driven by a serpentine belt (drive belt).
The generator is a maintenance-free unit. For some cars it can take up to 10-15 years without repair. If a generator fails, the car may still be running for a short time. However, the engine stops as soon as the battery is exhausted. Replacing
the generator with new OEM parts is expensive, but there are alternatives.


While many assume that the car's battery is fueling all of these fuels, the truth is that the battery only switches on the electronics when the engine is turned off: starts the engine. And for a limited time. Once the engine is running, the generator takes over and transports the energy.

Car engines run on air, fuel and sparks. Although the battery provides the first electricity needed for the first spark, it only has enough power to make the car a few kilometers away. The generator comes here. It constantly charges the battery when the car is in motion while simultaneously operating all the electronic parts of the vehicle. This means that although most cars have a battery voltage of 12, the generator typically provides a voltage of between 13.5 and 15 V.


The generator consists of a voltage regulator and three main components: the stator, the rotor and the diode. When the battery is first powered by the car, the generator belt or belt rotates the generator pulley, resulting in a very fast rotation of the rotor inside the generator. This rotor, which is essentially a magnet or magnet group, is located in a copper wire nest, which is called a stator.

Electromagnetism generates electricity by turning the magnets at an incredible speed. The electricity used in this way is transmitted through copper wires to a diode, which modifies the AC current to DC, the current used by the car.


If a car generator fails, drivers will notice that they have reduced electrical capacity, which often results in blurred light. But these traces do not last long because the partially charged battery usually has enough power to handle objects such as headlights and electric windows, but the next time the vehicle starts, it fails.
There is usually a dash of light, also called a battery indicator, because it is often the shape of a small element that warns the drivers of generators that do not provide enough power to run the system. . The car owners involved can also check the charging system or encounter an electric problem with the car.


It is essential to always do a thorough check on it periodically in-order to prevent damage.
