Alternator Components

1.Pulley: A pulley on the exterior of your Alternator is turned by a drive or serpentine belt connected to the engine’s crankshaft. This movement powers the Alternator by providing mechanical energy that it can convert into electricity.

2.Rotor: The rotor is a cylindrical part inside your Alternator. It has winding and magnetic poles arranged in a triangular pattern, alternating between north and south. As it spins, the rotor becomes an electromagnet. 

3.Stator: The stator encases the spinning rotor and contains three copper wire windings. As the rotor spins, it generates alternating current (AC) in these windings.

4.Voltage Regulator: The voltage regulator controls the rotor's electrical input, preventing too much voltage output from the stator from damaging your car’s battery and other electronics. It adjusts the electricity powering the rotor to keep the desired Alternator output.

5.Rectifier: Car batteries work with a direct current (DC) charge, but the stator creates an alternating current (AC) charge. The rectifier converts the AC charge into a DC charge so the power is compatible with your battery.
