The Cummins 4365704 Alternator is a component designed for use in commercial trucks. It plays a role in maintaining the vehicle’s electrical system by generating power to charge the battery and supply electricity to various electrical components while the engine is running ¹.

Basic Concepts of Alternators

An alternator is a device that converts mechanical energy into electrical energy. It functions by using a rotor that spins within a stationary stator, generating an alternating current (AC) that is then converted into direct current (DC) by a rectifier. This DC power is used to charge the vehicle’s battery and power electrical systems. Alternators differ from generators in that they produce AC that is converted to DC, whereas generators directly produce DC ².
