The Cummins 4974301 Alternator is a component designed for use in commercial trucks. It serves a role in the vehicle’s electrical system by generating electrical power to charge the battery and supply electricity to the truck’s various electrical components while the engine is running. Understanding its function and significance is important for maintaining the truck’s overall performance and reliability.

Basic Concepts of Alternators

An alternator is a device that converts mechanical energy into electrical energy. It operates by using a rotor that spins within a stationary set of coils, known as the stator, to generate alternating current (AC). This AC is then converted into direct current (DC) by a rectifier, which is used to charge the battery and power the truck’s electrical systems. Alternators differ from generators in that they produce AC, which is then converted to DC, whereas generators directly produce DC ¹.
