A tensioner belt pulley is part of the vehicle's serpentine belt system, which drives multiple accessories such as the alternator, water pump, power steering pump, and air conditioning compressor. The tensioner itself is a spring-loaded or hydraulic device that maintains tension on the serpentine belt, ensuring it remains tight enough to function properly without slipping or breaking. The pulley, which is an integral part of this mechanism, assists in guiding the belt around the engine's various pulleys while providing the necessary tension.

Stepper motors are a fundamental component in modern engineering, widely used in applications requiring precise control of movement. Unlike traditional motors that continuously rotate, stepper motors divide a full rotation into a series of steps, allowing for accurate positioning without needing feedback from sensors. This makes them particularly valuable in robotics, CNC machines, and 3D printers, where precision is critical. One essential aspect of stepper motor systems is the use of belts, which facilitate efficient power transmission and movement control.
