Our Review
After integrating the Stepper Motor Nema 17 3.4cm 26Ncm 0.4A 12V Nema17 Step 42BYGH 4-Lead(3PCS) into several test builds, we found it to be a capable component for the price. Key specs include Step Angle: 1.8 degrees (200 steps/rev), Rated Current: 0.4A, Holding Torque: 26 Ncm.
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.
The Stepper Motor Nema 17 3.4cm 26Ncm 0.4A 12V Nema17 Step 42BYGH 4-Lead(3PCS) earns its place in the parts bin. Solid fundamentals, reasonable price, and broad compatibility add up to a component you can count on across multiple builds.
What We Like
- Precise open-loop positioning without feedback encoders
- High holding torque keeps position under load
- Works with standard A4988/TMC2209 stepper drivers
- Smooth microstepping reduces vibration and noise
Watch Out For
- Loses steps at high speeds without acceleration ramping
- Wire color coding varies between manufacturers
- Requires a stepper driver board (not included)
