Our Review
The Nema 17 Stepper Motor 2 Phases 1.8° DC 4.1V Motor Fits for Extruder delivers solid performance for its category. With Step Angle: 1.8 degrees, Rated Current: 1.0A per phase, Holding Torque: 40 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 Nema 17 Stepper Motor 2 Phases 1.8° DC 4.1V Motor Fits for Extruder delivers what you need without unnecessary complexity. Recommended for hobbyists and engineers working on projects where motors & actuators components are essential.
What We Like
- Reliable bipolar winding configuration for consistent torque
- Smooth microstepping reduces vibration and noise
- Works with standard A4988/TMC2209 stepper drivers
- Affordable replacement for 3D printer and CNC upgrades
Watch Out For
- No position feedback — open-loop only
- Wire color coding varies between manufacturers
- Draws full rated current even when stationary (gets warm)
