Although it might seem like an overwhelming amount of information, learning more about the role of an alternator will help you notice issues before they become severe.

What Does the Alternator Do In a Car?
What does the alternator do in a car? According to firestonecompleteautocare.com, an alternator is a small, cylindrical generator that is most often bolted to the engine. It’s one of the three critical components of the engine charging system, working alongside the battery and other components to ensure the vehicle continues.
The alternator brings forward forms of electricity that go into storage inside the battery. It takes mechanical energy that comes to life when the car is in motion, typically using a serpentine belt or something similar and converts the mechanical energy into chemical energy for use in the future.
An alternator is critical. Without it, the car would have a trickier time functioning and potentially die.

Critical Components of an Alternator
An alternator isn’t just a cylinder. Various components inside the cylinder help the alternator complete its job correctly.
There are several critical components in an alternator, including the following items:
- Pulley: This pulley is moved by a belt and causes mechanical energy in the system.
- Rotor: The rotor has magnets on the outside and becomes energized, turning into an electromagnet.
- Stator: The stator covers the alternator rotor as it spins, inducing stator windings.
- Rectifier: The rectifier converts an alternating energy charge into a direct power that works with the battery inside the car.
- Voltage regulator: Lastly, the voltage regulator protects your vehicle from too much voltage introduced to the system.
These help the alternator function at its highest capacity.
The battery might be valuable for ensuring your car will turn on again after it’s been off, but the alternator secures your car’s life while it’s on the move. It works hand in hand with other valuable components that keep your system alive, so you shouldn’t ignore any indications that there is something wrong if they happen to make an appearance.
