What is the alternator and how does it work?
By definition, an alternator is a device that converts mechanical energy into AC electrical energy. In a vehicle, the engine turns a drive belt that rotates a pulley attached to the alternator. But wait a minute… Doesn’t a vehicle require DC voltage? Indeed, it does… but we’ll get to that later.What does an alternator do in a vehicle?
The alternator is a mechanical device that converts mechanical energy into electrical energy. Its function is to generate electricity to power other electrical units of the car such as headlights, radio, ignition system and air-conditioning compressor.What is an alternator and what does it do?
The alternator is essentially a small generator running under your hood. Driven by a belt on the engine, it turns mechanical motion into electrical energy. This is accomplished by a spinning magnetic rotor inside armature coils, inducing electricity in the form of alternating current. This current must be rectified by diodes to become direct ...
