La courroie serpentine est une longue bande de caoutchouc qui est enroulée autour de plusieurs poulies. Contrairement aux courroies traditionnelles qui n'entraînaient qu'un seul appareil, la courroie serpentine peut transmettre le mouvement à plusieurs composants de manière synchronisée. Cela permet de gagner de l'espace et de réduire le poids du moteur. En effet, un moteur équipé d'une courroie serpentine nécessite moins de composants qu'un moteur avec plusieurs courroies distinctes.

3. Fabric-reinforced Materials Flat belts may also be constructed from fabric-reinforced materials, typically combining textiles with rubber or polyurethane layers. This reinforcement provides additional strength and flexibility while still allowing for a lightweight design. Fabrics like polyester or cotton are often used, and the choice of fabric can significantly affect the belt's performance characteristics, such as its ability to handle loads and resist wear.

However, flat belts also have disadvantages. Their efficiency can decrease significantly under heavy loads, as they rely on friction to transmit power. This limitation can lead to slippage, especially when the load exceeds the belt's capacity. Consequently, flat belts are less suitable for high-torque applications where a consistent grip is essential. Furthermore, the alignment of the pulleys must be precise; any misalignment could cause significant wear or failure.
