Basic Concepts of an Alternator

An alternator is a device that converts mechanical energy into electrical energy. It consists of several key components: the rotor, stator, rectifier, and voltage regulator. The rotor, a rotating electromagnet, spins within the stator, a stationary set of windings. As the rotor spins, it creates a magnetic field that induces an alternating current (AC) in the stator windings. The rectifier converts this AC into direct current (DC), which is then regulated by the voltage regulator to maintain a consistent output voltage ¹.
