This NEMA 16 hollow-shaft stepper motor (39HJA525-13K) delivers 0.2 N·m (28.4 oz·in) of holding torque in a 39 × 39 mm frame with a compact 25 mm body length. It features a 1.8° step angle, 0.7 A rated current per phase, 4-lead bipolar wiring, and a hollow shaft with a Φ8 mm outer diameter and a Φ5.5 mm inner bore, operating on 12–24 VDC and weighing just 0.12 kg. Its hollow bore allows cables, tubing, or optical paths to pass directly through the axis of rotation, making it well suited to compact rotary stages, medical and laboratory automation, optical scanning systems, cable-routing robotic joints, and space-saving automated inspection equipment. The matched drive is M322C.
