AW60HS Series — 60mm Stepper Motor with Precision Planetary Gearbox
The AW60HS series pairs Apexwell's NEMA 24 (60mm), 1.8° hybrid stepper motor with an HPS60 precision planetary gearbox, offering motor holding torque from 1.25 N·m to 2.8 N·m and rated output torque up to 32 N·m after reduction. With two available gear-train stages and reduction ratios from 3:1 to 100:1, backlash is held to ≤15 arcmin at no load. The HPS60 gearbox is shared with Apexwell's AW57HS precision series, so this line delivers the same output torque range from a higher-current, higher-holding-torque motor stack.

Momentary torque moment is rated at two times the rated allowable load across both stages. 15 reduction ratios are available in total (3 to 100:1); because the AW60HS uses the same HPS60 gearbox as the AW57HS, rated output torque tops out at the same 32 N·m, with the difference between the two series coming from motor holding torque and current rating ahead of the gearbox.
Typical Applications
With backlash held to ≤15 arcmin, motor holding torque up to 2.8 N·m, and gearbox output torque up to 32 N·m, the AW60HS precision series fits industrial robotic base joints, precision CNC and index tables, semiconductor and electronics production equipment, and other heavier positioning tasks where the AW57HS's torque range fits the gearbox requirement but the driving application calls for a higher-current, higher-holding-torque motor stack.
Why Choose the AW60HS Precision Gearmotor
Backlash of ≤15 arcmin makes this series suitable for applications where positioning repeatability matters more than cost, even at industrial torque levels. Because the HPS60 gearbox platform is shared with the AW57HS precision series, a design can move between the two motor frames without changing gearbox dimensions or reduction ratio options. Fifteen reduction ratios across two gear-train stages let torque and speed be tuned within a single mounting footprint, and noise is held to ≤55 dB. For applications where the AW57HS's motor torque is sufficient, that series offers the same gearbox platform with a lower-current motor. For applications where backlash tolerance is less critical, Apexwell's standard planetary gearmotor line on the same frame offers a lower-cost alternative. Custom shaft configurations and encoder feedback are available on request.
We can customize the electrical parameters of the motor and geometric dimensions such as the motor output shaft size according to customer requirements. Accessories including pulleys, eccentric gearboxes, planetary gearboxes and encoders can also be added.
