Operating within the standardized 42x42mm NEMA 17 frame size, this specific model delivers a highly reliable 40 N.cm (4000 g.cm) of holding torque. This means it has the muscular strength required to rapidly push a heavy 3D printer heated bed back and forth without skipping steps or losing its exact coordinates. Pre-wired with a generous 60cm 4-lead cable and designed for easy integration with standard driver boards, it is the fundamental building block for any project requiring accurate, repeatable CNC motion.

Key Features & Functional Advantages

  • Precision Stepping: Features a 1.8-degree step angle (200 steps per revolution), providing ultra-fine positional accuracy that can be further enhanced using microstepping drivers.

  • Reliable Holding Torque: Delivers a solid 40 N.cm of holding torque, ensuring your mechanical axes hold their exact position firmly against physical resistance and tool pressure.

  • Standardized Frame: The universal 42mm NEMA 17 faceplate makes it instantly compatible with thousands of open-source 3D printable brackets, aluminum profiles, and linear rails.

  • 4-Wire Bipolar Interface: Uses a simple 4-lead wiring configuration that connects effortlessly to standard hobbyist stepper motor driver chips.

  • Durable Construction: Built with a high-quality laminated core and precision ball bearings to ensure smooth, low-friction rotation even during extended 12-hour 3D printing jobs.

Perfect For

  • Desktop 3D Printers: The absolute go-to motor for driving the X and Y axis timing belts, as well as pushing plastic filament through the extruder assembly.

  • DIY CNC & Lasers: Controlling the precise focal position and gantry movement on lightweight desktop laser engravers and PCB milling machines.

  • Camera Sliders: Providing the ultra-smooth, perfectly paced linear motion required for professional time-lapse photography rigs.

  • Robotic Arms: Acting as the base rotational joints for medium-sized, highly accurate robotic manipulators and automated pick-and-place machines.
