The Cummins 3103026 Alternator is a vital component in the electrical system of commercial trucks. Its purpose is to generate electrical power to charge the vehicle’s battery and supply electricity to the truck’s electrical systems while the engine is running. This part ensures the continuous operation of electrical components, enhancing the overall performance and reliability of commercial trucks.

Basic Concepts of an Alternator

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 alternators produce AC, which is then converted to DC, whereas generators directly produce DC ¹.
