The alternator is an electronic component that is belt driven. The alternator is used to charge the storage battery during engine operation. The alternators that are covered by this manual are cooled by an internal fan. The internal fan pulls air through vents in the case. The air exits through the vents that are in the side of the alternator.
The alternator converts a combination of mechanical energy and magnetic energy to alternating current (AC) and voltage. This process is done by rotating a direct current (DC) electromagnetic field (rotor) inside a three-phase stator. The alternating current and voltage are generated by the stator. The current and voltage are changed to direct current by a three-phase full wave rectifier. The rectifier uses six silicon rectifier diodes.
The alternator excites the field coil by using battery power and self-excitation. The alternator has a semiconductor-type regulator in the rear of the unit.
