Alternator pulley

Alternator pulley

Alternator pulley

The alternator produces electricity using electromagnetic induction. It is made up of four parts, including: the rotor (the rotating part), the stator (the fixed part), the diode bridge (channels energy from the stator), and the regulator (manages the excitation of the rotor to stabilize the voltage issued). All these parts represent the internal system that produces electricity through the rotation of the rotor. However, the rotor needs an external force to initiate this rotation. The alternator pulley is the part which allows this rotation to begin. The pulley, along with the drive belt, works together to transfer the rotational motion of the crankshaft to the alternator.

What types of pulleys can you find?

Alternator pulleys are varied and of various shapes and functions. They are distinguished from each other by the shape of the drive belts and the function of the alternators. The different types of pulleys found are:

-           The polyV profile pulley

-           The trapezoidal profile pulley

-           The freewheel pulley or declutchable pulley

-           The decoupling pulley

What are the symptoms of a faulty pulley?

First of all, you have to be attentive to noises. When the belt is misaligned or the wrong width, you will hear belt noise. Rolling noises from scrap metal linked to the pulley release system are also signs that should not be overlooked.

In our alternator spare parts category, we offer many models of pulleys including declutchable alternator pulleys from the brands INA, VALEO, BOSCH, CARGO. We also offer tools for alternator pulleys as well as fixed pulleys for alternators. We have made the effort to choose our suppliers carefully in order to offer you the best products at affordable prices.
