The PHG42S Series NEMA 17 stepper gear motors combine compact size, long life, and high precision with integrated planetary gearboxes. Featuring a 1.8° step angle, these motors offer smooth movement, minimal backlash (≤60 arcmin), and low noise (≤60 dB). With staged gear ratios, rated admissible torque ranges from 0.3 N·m to 2.5 N·m, and efficiency up to 90%, they are ideal for industrial automation, and precise motion control applications requiring compact, high-performance stepper gear motors.
