This Leadshine 28CM013 NEMA 11 2-phase hybrid stepper motor delivers 0.12–0.13 N·m (17–18 oz·in) of holding torque in a compact 28 × 28 mm frame with a 51.8 mm body length, weighing just 0.2 kg. It features a precise 1.8° step angle, 4-wire bipolar wiring, a Φ5 mm shaft (20 mm length, 15 mm D-cut), IP40 protection, and Class B insulation, with a rated current of 1.5 A per phase (standard catalog rating is 1.2 A) at 12–24 VDC. Designed for open-loop control and matched with the M322C digital stepper drive, it is built for low heating and smooth, reliable motion. Its compact 28 mm frame makes it well suited to space-critical precision axes in desktop 3D printers, small CNC routers and engravers, laser marking and processing equipment, medical and analytical instruments, automated dispensing systems, and miniature robotic joints where open-loop positioning is sufficient. The matched drive is M322C.
