The PHG28Y Series NEMA 11 stepper gear motors feature compact size, long life, and high precision with integrated planetary gearboxes. With a 1.8° step angle, low inertia, and smooth operation, these motors provide staged gear ratios for rated admissible torque from 0.3 N·m up to 2.5 N·m. They offer minimal backlash (≤60 arcmin), low noise (≤60 dB), and high efficiency (up to 90%), making them ideal for miniature automation, and precision positioning applications where compact, reliable performance is required.
