An alternator is a generator that produces the electricity stored in a vehicle’s 12-volt battery and powers the starter motor for the engine and the various computers, lights, power windows and locks, ...

Modern automotive alternators have a voltage regulator built into them. Typical car alternators generate the field using a DC current through slip rings. The field current is much smaller than the ...

Have you ever wondered about the electricity that courses through your car? Do you suspect that there's a captive bolt of lightning held in a magic jar? Of course you don't. You're not a Neanderthal.

The charging system in a car is often the most confusing part of the whole electrical system, but its purpose is actually pretty easy to understand. There are three main components in a charging ...

You can find stators in many types of electric generators, motors, and rotors. A stator is also the part of the alternator that’s stationary (while the rotor, also called the flywheel, moves).

It doesn’t matter whether it’s in the deep chill of winter or the heat of summer, on a work truck, emergency vehicle, or personal rig—the last thing a driver wants to see or hear are dim headlights ...

In the mid '70s, GM began offering its SI-series (Systems Integrated) alternators, which not only delivered more amperage but did away with the externally mounted voltage regulator and its messy ...

In this video, we explore the voltage output of an alternator when driven by a waterjet. It’s an engaging science experiment that showcases the interaction between water pressure and electrical ...
