Size 35mm NEMA 14 Stepper Motor 0.2 N-m/0.3 N-m/0.4 N-m with Magnetic Hole

This NEMA 14 bipolar stepper motor series (35mm frame) offers holding torque options of 0.2 N·m, 0.3 N·m, and 0.4 N·m, with body lengths of 36 mm, 48 mm, and 60 mm respectively. Each model features a precise 1.8° step angle, 4-wire bipolar wiring, rated currents from 1.0 A to 1.2 A per phase, and a standard Φ5 mm shaft, operating on a typical 12–24 VDC supply. The defining feature is a rear magnetic hole that enables direct mounting of a magnetic encoder for closed-loop feedback or provides convenient shaft access. This combination of compact size, scalable torque, and encoder-ready design makes the series well suited to precision motion axes in desktop 3D printers, small CNC routers and engravers, automated pick-and-place heads, laboratory and medical instruments, and light-duty robotic joints requiring reliable open- or closed-loop positioning. The matched drive is M322C.
