NEMA17 4.4 kg Stepper Motor for CNC, 3D Printer, Robotics & Arduino Projects

The NEMA17 4.4 kg-cm Single Shaft Stepper Motor is a compact and high-precision bipolar stepper motor designed for smooth motion control and accurate positioning applications. With a fine 0.9° step angle and 400 steps per revolution, this motor delivers better positioning accuracy and smoother movement compared to standard 1.8° stepper motors, making it suitable for CNC machines, 3D printers, laser engravers, camera sliders, robotics, automation systems, and DIY engineering projects.

Built with a durable brushless motor structure, the NEMA17 stepper motor provides reliable long-term performance with stable torque output and low vibration. It offers up to 4.4 kg-cm holding torque while operating at 1.68A per phase, making it ideal for medium-load precision motion applications. The motor responds efficiently to start, stop, and reverse commands from compatible stepper motor drivers, ensuring smooth and controlled operation.

Its compact 42 x 42 x 48mm body design with a 5mm single shaft allows easy installation in space-constrained projects and mechanical assemblies. The motor can be easily interfaced with Arduino, Raspberry Pi, CNC controllers, GRBL systems, and other microcontroller platforms using suitable stepper motor drivers such as A4988, DRV8825, or TB6600.

This stepper motor is widely used in educational projects, industrial automation systems, robotic platforms, pick-and-place machines, XY plotters, and precision positioning equipment where consistent motion control and accuracy are required.
