Electric Motor 2‑Phase 42 Stepper 1.8 Degree 0.28Nm Stepping Driver NEMA17 Replacement

1、Imported high‑quality motor steel sheets, bearings made of German technology, low self‑inductance, good responsiveness.

2、The product can be directly connected to the load and run at low speed in a state of close to a locked rotor without gear reduction.

3、The product can produce a high torsion‑to‑inertia ratio on the loaded shaft, and can eliminate system errors caused by the use of reduction gears.

4、The inner rotor adopts German technology, and the surface is coated with imported rotor glue to prevent burrs on the surface after carbon steel oxidation and grinding, resulting in increased motor noise.

5、The front and rear covers are perfectly connected, the body is black electrophoresis, high‑end atmosphere, and the body size is standard.
