8501.51.40.20 - Gear motors 🖩

This HTS category, 8501.51.40.20, specifically classifies gear motors that are AC, multi-phase, and fall within a defined power output range. A gear motor is a type of electric motor that has a gearbox integrated into it. This combination is designed to provide torque and speed reduction, making it suitable for applications requiring precise control over motion. The power output for motors classified here must exceed 74.6 Watts but not surpass 735 Watts, indicating a specific tier of fractional horsepower motors with enhanced torque capabilities due to the integrated gearing.

Distinguishing this category from its sibling, 8501.51.40.40 ("Other"), is crucial for accurate classification. While the sibling category captures other AC, multi-phase motors within the same wattage range that are not gear motors, this category is exclusively for those with an integrated gearbox. This distinction emphasizes the functional difference: the presence or absence of a gear reduction mechanism is the primary differentiator. Therefore, if an AC, multi-phase motor within this wattage bracket includes a gearbox to alter its output speed and torque, it will fall under this specific classification.

As this HTS code represents a leaf node in the provided hierarchy, there are no further subcategories. Classification at this level is determined by the combination of motor type (AC, multi-phase), presence of a gearbox, and the specific power output range (exceeding 74.6 W but not exceeding 735 W). Practical examples include small, integrated motor-gearbox units used in automated machinery, conveyor systems, or consumer appliances where controlled rotational force is required.
