This NEMA 17 planetary gear stepper motor is designed for robotic arm and automation applications. Single shaft and dual shaft versions are available for flexible mechanical integration. Featuring high precision positioning, compact gearbox structure, and multiple reduction ratios, this robot arm stepper motor is ideal for desktop robots, collaborative robots, and 3D printed robotic arm systems.
This compact robot arm stepper motor integrates a high precision NEMA 17 hybrid stepper motor with a planetary gearbox for stable low-speed high-torque operation.
It is specially designed for robotic arm joints, collaborative robots, desktop automation systems, and educational robotics platforms.
Both single shaft and dual shaft versions are available.
The double shaft design allows encoder installation, manual adjustment, and synchronized transmission structures for advanced robotic motion control systems.
