The mechanical structure of small vending machines can be precisely selected according to the scenario. For mini desktop and small compartment snack vending machines with limited space for pushing goods and lightweight gate structures, the XQ-S2007D micro digital servo motor is the preferred choice. Its compact and lightweight body, 7kg・cm torque is sufficient for pushing regular snacks and small items. Stainless steel gears combined with an aluminum shell for heat dissipation ensure precise positioning and resistance to frequent starts and stops. For the mainstream dispensing and gate structures of regular small snack and bottled beverage vending machines, the XQ-S3115M digital servo motor is recommended. It boasts a high torque of 15kg・cm, IP67 dust and moisture resistance, metal gears to prevent stalling, and is suitable for high-frequency commercial dispensing. Its universal installation size offers excellent compatibility. For heavy-duty bottled beverage aisles, the XQ-BLS8125D brushless servo motor can be selected, offering a high torque of 25kg and a longer service life. The entire XQ-Power series of vending machine-specific servos supports multi-angle adjustment, adapts to various mechanical strokes, can be customized with parameters as needed, and is industrially certified, ensuring long-term stable operation of small vending machines.
