alternator

An alternator is an essential component in modern vehicles, serving as the primary source of electrical power once the engine is running. It converts mechanical energy into electrical energy, supplying power to the vehicle's electrical systems and recharging the battery. Unlike older generators, alternators can efficiently operate at low engine speeds, ensuring the battery remains charged even during idle periods or at slow driving speeds. This capability is crucial for supporting the vast array of electrical components found in today's vehicles, from lighting and entertainment systems to advanced driver-assistance systems.

The core principle behind an alternator's operation is electromagnetic induction. Inside the alternator, a rotor spins within a stationary set of coils known as the stator. As the engine runs, it drives a belt connected to the alternator's pulley, causing the rotor to spin. This rotation generates alternating current (AC) electricity as the magnetic field from the
