8501.51.60.20 - Gear motors

This HTS category, 8501.51.60.20, specifically classifies gear motors. Gear motors are integrated units combining an electric motor with a gear reduction system, designed to reduce speed and increase torque. These are distinct from standard AC motors as they incorporate a gearbox to achieve specific rotational output characteristics required for driving machinery and equipment. The key defining feature is the presence of the integral gear train for speed reduction and torque amplification.

Within the "Other" subcategory at this level, 8501.51.60.20 differentiates itself from its sibling category, 8501.51.60.40, by its specific inclusion of gear motors. While both fall under "Other AC motors, multi-phase, of an output not exceeding 750 W," this code is dedicated to units where the gearbox is an inherent component of the motor assembly. The sibling category would encompass other types of AC motors not specifically defined as gear motors within this output range.

As this is a leaf node, there are no further subcategories. Classification within 8501.51.60.20 relies on the core definition of a gear motor with an AC, multi-phase motor of an output not exceeding 750 Watts, where the gear reduction mechanism is an integral part of the unit for torque and speed manipulation.
