The alternator pulley is a component that allows the vehicle's alternator to be controlled by a belt. Whether it be a v-type belt or a serpentine drive belt, the alternator gets the current it needs from the belt's rotation.
Alternator pulley principlesThe purpose of the alternator is to supply a charging procedure for the vehicle's electronics. The alternator that is in every vehicle is operated by a belt, and any type of fan belt the user uses will be compatible with the alternator pulley. The alternator pulley is usually attached to the main shaft of the alternator.
The use of the alternator pulley is to transfer torque to the alternator. Modern cars use a single belt to drive all the parts, while older vehicles need a total of three separate belts. With an increase in features that are power-operated, the workload for the alternator has intensified. This leads to a bigger and more powerful alternator, but it also requires a different drive system.
