Size 42mm (NEMA 17) Economy Stepper Planetary Geared Motor 1 deg 0-100 RPM Max. 4.0 N-m

This 42 mm (NEMA 17) stepper planetary geared motor combines a high-torque bipolar stepper with an economy planetary gearbox, delivering up to 4.0 N·m of rated output torque and ≤1.0 deg backlash for demanding low-speed, high-torque positioning. The integrated package features a standard 1.8° step angle, 4-wire bipolar wiring, a Φ8 mm flat output shaft, and operates on a 12–24 V DC supply, with typical motor phase currents around 1.33 A/1.68 A/2.1 A and output speeds up to 100 RPM. Its robust 42 × 42 mm frame and high gear reduction make it well suited to heavy-duty automation axes in CNC routers and engravers, industrial robotics, automated production lines, packaging machinery, and large-format positioning systems where reliable torque multiplication and repeatable accuracy are essential. The matched drive is M322C. Please specify the model number in the order note.
