8501.40.20 - Of an output exceeding 37.5 W but not exceeding 74.6 W

This HTS category encompasses AC (alternating current) single-phase electric motors specifically designed for applications where their output power falls within a defined range. These motors are characterized by an output exceeding 37.5 Watts (W) but not exceeding 74.6 Watts (W). This precise power output specification is the primary criterion for classification within this particular subheading, distinguishing them from motors with lower or higher power ratings.

Compared to sibling categories, this subheading clearly differentiates itself based on its power output. For instance, category 8501.40.40 covers motors with a higher output range, starting from over 74.6 W up to 735 W, while 8501.40.50 includes motors exceeding 735 W but under 746 W. The "Other" category (8501.40.60) at this level would encompass AC single-phase motors not fitting any of the specific power output ranges defined in the preceding subheadings.

This category is further subdivided to account for distinct functional variations within the specified power range. The subcategories, "Gear motors" (8501.40.20.20) and "Other" (8501.40.20.40), allow for a more granular classification. Gear motors in this classification incorporate a gear reduction system to modify speed and torque, whereas the "Other" subcategory is for AC single-phase motors within the 37.5 W to 74.6 W output range that do not feature an integrated gearing mechanism.
