timing belt motor

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.

The serpentine belt, an integral component of modern automotive engines, plays a crucial role in the functioning of various engine accessories. It is a single, continuous belt that weaves around multiple pulleys and drives several components, including the alternator, power steering pump, water pump, and air conditioning compressor. The efficiency and reliability of a serpentine belt can significantly affect the overall performance of a vehicle, making it essential for drivers to understand its function and maintenance.
