Overview

Bring precise, reliable motion to your build with the Usongshine Nema17 stepper motor, a compact 42BGYH frame motor engineered for CNC laser engraving machines, 3D printers and other motion-control projects. With a 1.8 degree step angle and a 9 N.cm holding torque, it delivers smooth, repeatable positioning that keeps your prints and cuts sharp.

Each motor runs on a low 0.7 A per phase over a standard 4-lead bipolar setup, so it pairs easily with common stepper drivers and controller boards. The NEMA17 footprint is the industry standard for desktop machines, making this a straightforward drop-in choice for upgrades, replacements or brand-new builds.
