Our Review
After integrating the Stepper Motor Nema 17 48mm 42BYGH Stepping 2A 4-Lead 1m Cable 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: 2A, 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.
For the price point, the Stepper Motor Nema 17 48mm 42BYGH Stepping 2A 4-Lead 1m Cable delivers what you need without unnecessary complexity. Recommended for hobbyists and engineers working on projects where motors & actuators components are essential.
What We Like
- Smooth microstepping reduces vibration and noise
- Precise open-loop positioning without feedback encoders
- High holding torque keeps position under load
- Reliable bipolar winding configuration for consistent torque
Watch Out For
- Draws full rated current even when stationary (gets warm)
- Loses steps at high speeds without acceleration ramping
- Requires a stepper driver board (not included)
