AW60HS Series — NEMA 24 Stepper Motor with Eccentric Gearbox
The AW60HS series pairs Apexwell's NEMA 24 (60mm), 1.8° hybrid stepper motor with a 2GN-K eccentric gearbox, scaling motor holding torque from 1.25 N·m to 2.8 N·m across four body lengths. The gearbox platform is shared with the AW57HS eccentric-gearmotor series, offering the same 22 reduction ratios from 3:1 to 250:1 and up to 24.5 N·m of maximum permissible output torque from a higher-current motor stack.

Motor Model Comparison
| Model | Body Length | Phase Current | Phase Resistance | Phase Inductance | Holding Torque | Rotor Inertia | Mass |
|---|---|---|---|---|---|---|---|
| AW60HS56-4204A | 56 mm | 4.2 A | 0.40 Ω | 1.6 mH | 1.25 N·m | 478 g·cm² | 0.58 kg |
| AW60HS65-2804A | 65 mm | 2.8 A | 0.95 Ω | 2.5 mH | 1.40 N·m | 590 g·cm² | 0.58 kg |

Wiring
Each AW60HS motor is available in either 4-wire (bipolar) or 6-wire (center-tap) configuration, so it can drop into either a bipolar or unipolar driver setup without a different motor SKU.
2GN-K Eccentric Gearbox Specifications
| Reduction Ratio | 3–15 | 18–250 |
|---|---|---|
| Gearbox Length (L1) | 32 mm | 42 mm |
| Max Torque Moment | 1.2–5.4 N·m | 7–24.5 N·m |
22 reduction ratios are available (3, 3.6, 5, 7.5, 9, 10, 12.5, 15, 18, 20, 25, 30, 36, 50, 60, 75, 90, 100, 120, 150, 180, 250:1). Max torque moment plateaus at 24.5 N·m from ratio 60:1 upward — identical to the AW57HS gearbox, since both series share the same 2GN-K platform.
Typical Applications
With 22 reduction ratios and gearbox torque up to 24.5 N·m, the AW60HS eccentric-gearmotor series fits conveyor indexing, packaging machinery, valve and damper actuation, and light-to-mid industrial positioning tasks where the AW57HS's torque range fits the gearbox requirement but the driving application calls for a higher-current motor stack.
Why Choose the AW60HS Eccentric Gearmotor
The 22-ratio range on a single 2GN-K gearbox platform lets one motor selection be tuned across a wide speed/torque window without redesigning the mechanical interface, and the 4-wire/6-wire choice lets it match either driver type. Because the gearbox platform is shared with the AW57HS, a design can move between the two motor frames without changing gearbox dimensions or ratio options. 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.
