Description

Nema17 is the most widely used stepper motor in the world, featuring a 42mm square flange and industry-standard mounting pattern (31mm hole spacing). The two-phase hybrid design delivers holding torque from 0.3Nm to 0.9Nm, with high-torque versions reaching 1.2Nm. Step accuracy is ±5% non-accumulative. The motor uses high-quality neodymium magnets and precision-machined rotors for consistent performance. We provide optional motors such as IP65 waterproof versions, high-temperature versions, low-noise versions, and with integrated encoders. Planetary gearboxes, spur gearboxes, and lead screw assemblies can be matched for enhanced performance.

Wide range of Nema17 configurations:

Frame size 42mm, step angle 1.8° or 0.9°, holding torque 0.3–1.2Nm, rated current 0.8–2.5A, IP20 to IP65 protection.
