Our Review
The Stepper Motor Nema 17 Dual Shaft 1.68A 44Ncm 42x48mm Nema17 4-Lead delivers solid performance for its category. With Step Angle: 1.8 degrees (200 steps/rev), Rated Current: 1.68A, Holding Torque: 44 Ncm, it covers the essentials that most makers and engineers need for their projects.
Mechanical performance was consistent in our testing. Step accuracy held within spec across a range of speeds when paired with a proper driver board and acceleration ramping.
Wiring was straightforward. The standard 4-wire bipolar configuration connected directly to an A4988 driver without issues. Color codes matched common pinout charts.
For the price point, the Stepper Motor Nema 17 Dual Shaft 1.68A 44Ncm 42x48mm Nema17 4-Lead delivers what you need without unnecessary complexity. Recommended for hobbyists and engineers working on projects where motors & actuators components are essential.
What We Like
- Precise open-loop positioning without feedback encoders
- High holding torque keeps position under load
- Affordable replacement for 3D printer and CNC upgrades
- NEMA 17 mount pattern fits most CNC and 3D printer frames
Watch Out For
- Requires a stepper driver board (not included)
- Draws full rated current even when stationary (gets warm)
- No position feedback — open-loop only
