Quick Summary

An alternator is a machine that converts mechanical energy into electricity, primarily used in modern vehicles to power ignition, lights, and other systems. It generates electric power through a rotor field coil and a stator with a three-phase winding. A rectifier converts the alternating current (AC) output to direct current (DC), and a regulator maintains the correct voltage for the battery.1

An inductor alternator is a specific type of synchronous generator where both the field and output windings are located on the stator. Voltage is generated in the output windings through flux pulsations in the stator teeth, which are caused by a toothed rotor that varies the magnetic reluctance as it rotates. These alternators are useful for high-frequency generation and applications requiring high reliability due to the absence of rotor electrical connections.12
