Mazda CX-3 Alternator

The Mazda CX-3 Alternator is the small crossover powerhouse dynamo as it transforms engine rotation into a consistent stream of current that keeps the battery alive and all the onboard electronics operational. It has a two-piece aluminum shell with a shaft-mounted rotor, stator windings, bearings, a belt pulley and a cooling fan that provide reliable power even on extended summer drives. The Alternator also has integrated diodes that automatically switch the alternating current produced to direct current that is battery-friendly, hence the headlights, infotainment screens and advanced safety sensors remain bright and responsive every time the engine is running. Early models had a built-in regulator, but subsequent models allowed on-the-fly adjustment of field current by the Mazda Powertrain Control Module, reducing fuel consumption and increasing service life. Due to this clever development, the identical belt-driven hardware will work with all 2016-2021 CX-3 models with either the 2.0-liter gas engine or the budget-friendly 1.8-liter diesel. The fact that the Alternator is directly connected to the crankshaft pulley ensures that the supply of juice is constant in both the front-wheel and all-wheel-drive models of the crossover, continuing to keep the crossover as agile and efficient as it is. Running below output means that the battery lasts just a few minutes, which is why this simple piece of the system ensures performance and safety as it supplies ABS, stability control and emergency lights. The newer units have lighter, high-efficiency windings that reduce engine drag to add to the lively response that Mazda enthusiasts expect. The Mazda unit always stands out in a saturated market by integrating small dimensions, computer-based production and rough construction, which are needed in every CX-3 adventure.
