The PHG20Y Series NEMA 8 stepper gear motors combine high precision, long life, and compact design with planetary gearboxes for torque multiplication. Featuring 1.8° step angle, low inertia, and smooth operation, these motors are available with 1–3 stage gear ratios, providing rated admissible torque from 0.3 N·m up to 2.5 N·m. With minimal backlash (≤60 arcmin), low noise (≤60 dB), and high efficiency (up to 90%), PHG20Y motors are ideal for miniature automation, and precision positioning systems requiring reliable performance in a compact footprint.
