Description

Nema16 stepper motor is a 39mm two-phase hybrid stepper motor that offers reliable performance across a broad range of applications. With holding torque from 0.2Nm to 0.6Nm, it bridges the gap between small Nema14 and larger Nema17 motors. The motor features precision ball bearings and high-grade magnetic rotors for smooth rotation and long life. Step angle is 1.8°, and positioning accuracy is within ±5% non-accumulative. We provide optional motors with IP protection, customized winding, and encoder feedback for closed-loop operation. Planetary gearboxes and lead screws are also available.

Wide range of Nema16 configurations:

Frame size 39mm, step angle 1.8°, holding torque 0.2–0.6Nm, rated current 0.8–1.8A, multiple cable lengths and connectors.

Applications
