Our Review
The Stepper Motor Nema17 1.8deg 79Ncm 42 2.3A 42x42x67mm Nema 17 Step 4-Lead delivers solid performance for its category. With Step Angle: 1.8 degrees (200 steps/rev), Rated Current: 2.3A, Holding Torque: 79 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.
The Stepper Motor Nema17 1.8deg 79Ncm 42 2.3A 42x42x67mm Nema 17 Step 4-Lead 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
