Our Review
The Stepper Motor Nema 17 Planetary Gearbox Ratio 5:1/10:1/50:1/100:1 Nema17 Geared Φ8mm Output Shaft(Ratio 10 to 1) delivers solid performance for its category. With Step Angle: 1.8 degrees (200 steps/rev), Rated Current: 1.7A 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.
Overall, the Stepper Motor Nema 17 Planetary Gearbox Ratio 5:1/10:1/50:1/100:1 Nema17 Geared Φ8mm Output Shaft(Ratio 10 to 1) fills its role well. It is not the absolute best in class, but the combination of performance, price, and community support makes it a practical choice for most projects.
What We Like
- Works with standard A4988/TMC2209 stepper drivers
- High holding torque keeps position under load
- Precise open-loop positioning without feedback encoders
- Reliable bipolar winding configuration for consistent torque
Watch Out For
- No position feedback — open-loop only
- Requires a stepper driver board (not included)
- Draws full rated current even when stationary (gets warm)
