Basic Concepts of Alternators

An alternator is a device that converts mechanical energy into electrical energy, which is used to charge the battery and power the electrical systems of a vehicle. Unlike generators, which produce direct current (DC), alternators produce alternating current (AC), which is then converted to DC by a rectifier. The main components of an alternator include the rotor, stator, rectifier, and voltage regulator. The rotor, driven by a belt connected to the engine, rotates within the stator, which contains windings that generate electrical current. The rectifier converts the AC output to DC, and the voltage regulator ensures a consistent voltage level is maintained ¹.
