AW35HS Series — NEMA 14 Hybrid Stepper Motor
The AW35HS series is Apexwell's NEMA 14 (35mm) hybrid stepper motor line, offered across five body lengths from 28mm to 50mm. Holding torque scales from 0.22 N·m to 0.36 N·m, giving designers a step up in torque from NEMA 11 (AW28HS) while staying in a compact frame smaller than NEMA 17.

Typical Applications
The AW35HS's NEMA 14 footprint suits small 3D printer extruders, camera focus and gimbal mechanisms, medical device actuators, and light-duty robotics joints where NEMA 11 doesn't have enough torque and NEMA 17 is larger than the design needs.
Why Choose the AW35HS Series
Five body lengths on one NEMA 14 mounting interface give roughly a 1.6x torque range without changing the mechanical footprint. For applications where occasional step loss under load is a concern, see our article on why closed loop stepper motors are replacing traditional steppers to evaluate whether a closed loop configuration makes sense for your design. Custom shaft length and connector configurations 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.
