There are several types of stepper motors, including permanent magnet (PM), variable reluctance (VR), and hybrid stepper motors. Each type has unique characteristics, making them suitable for different applications. For instance, hybrid stepper motors combine features of both PM and VR stepper motors, offering better torque and accuracy. Regardless of the type, the interfacing of stepper motors with other mechanical systems often necessitates the use of belts.

One of the most significant risks associated with a faulty timing belt is the potential for catastrophic engine damage. If a timing belt fails while the engine is running, it can lead to severe internal damage. In interference engines, where the paths of the pistons and valves overlap, a broken timing belt can cause the pistons to collide with the open valves, resulting in bent valves, damaged pistons, and a complete engine overhaul. This can lead to repairs that cost thousands of dollars, making preventive maintenance a critical step for any machine operator.

Leather was the material of choice due to its natural strength and flexibility. Manufacturers utilized thick, tanned leather, often sourced from cattle hides, to produce these belts. The belts were typically flat, allowing them to fit smoothly over pulleys and reduce the risk of slippage. As the industrial landscape evolved, the design and manufacturing processes of flat leather drive belts also adapted, but their fundamental role in power transmission remained unchanged.
