Size 42mm (NEMA 17) HG Precision Stepper Planetary Geared Motor 10 arcmin 0-100 RPM Max. 15 N-m

This NEMA 17 precision stepper planetary geared motor (42HB-HG series) integrates a 42 × 42 mm bipolar stepper with a square-flange planetary gearbox, delivering output torque up to 15 N·m and output speeds from 0 to 100 RPM with a low backlash of ≤10 arcmin. It features a standard 1.8° step angle, 4-lead bipolar wiring, rated phase currents of 1.33 A or 2.0 A (depending on the motor stack length), and a driving voltage of 12–24 V DC, with a Φ10 mm keyed output shaft for secure load coupling. Its square-flange gearbox and high torque density make it well suited to low-speed, high-torque positioning tasks in CNC routers and engravers, automated pick-and-place systems, packaging machinery, rotary indexing tables, and industrial robotics where compact size and repeatable accuracy are essential. The matched drive is M322C. Please specify the model number in the order note.
