belt that goes around alternator

As the engine cranks, the rotational energy is transmitted through the PK belt to the alternator pulley. This rotation causes the rotor inside the alternator to spin, inducing a magnetic field. According to Faraday’s law of electromagnetic induction, this spinning magnetic field generates electrical current in the stator windings of the alternator. The result is an output of alternating current (AC), which is then converted into direct current (DC) through a built-in rectifier. This DC power is what charges the vehicle’s battery and powers the electrical systems.

When the vehicle's engine is running, it spins the crankshaft, which is connected to the serpentine belt. As the crankshaft turns, it drives the belt, which, in turn, rotates the pulleys attached to the alternator and other accessories. The alternator contains a rotor that, when spun by the belt, generates electrical energy through electromagnetic induction. This energy is crucial for keeping the car battery charged and powering various electrical components, from headlights to infotainment systems.
