Volvo S40 Alternator

The Volvo S40 Alternator is essentially designed to ensure that the battery is charged and all electronic systems operating onboard are powered as long as the engine is operating. A stationary stator winding and a shaft-mounted rotor are contained inside a two-piece aluminum shell, and as the drive belt rotor is spinning it causes a magnetic field that causes current to be induced in the stator windings. That alternating flow is then directed to the Alternator assembly which converts it into direct current by putting it through a rectifier filled with diodes and heat sinks in order that the battery and parts receive a constant stream of power. The heat accumulated on the pulley end is removed by a small cooling fan, and bearings at each end keep the rotor straight to provide smooth, silent rotation. Voltage should remain within a narrow range, and thus the previous generation relied on an external or internal regulator, but the powertrain control module on newer Volvo models automatically pulses the field current to prevent undercharging and overcharging as well. To achieve the factory level output, drivers are allowed to select fresh or remanufactured replacement parts for their Volvo, both of which are certified to the original equipment standard. In other Volvo models, this crucial generator has either standard field coils or, in a few special applications, permanent-magnet constructions, but the automotive application always remains identical. A healthy Alternator makes headlights bright, starts confidently, and makes sure the second S40 generation and its siblings perform reliably on a daily basis on each trip.
