Detailed Product Description:

For applications demanding high-precision, repeatable motion, the NEMA 17 Stepper Motor is the industry-standard choice. This specific model, with its impressive 4.2kg·cm holding torque, provides the power and reliability needed to drive heavy loads while maintaining perfect positional accuracy. As a bipolar motor with four wires, it requires a dedicated motor driver (such as an A4988 or DRV8825) to sequence the current through its two internal coils, enabling smooth and powerful motion in both forward and reverse directions.

A key technical specification is its precise 1.8° step angle, which translates to 200 steps per full revolution. This level of granularity makes it ideal for a wide range of tasks where exact positioning is critical. When combined with microstepping from a compatible driver, you can achieve even finer resolution, resulting in exceptionally smooth and quiet operation. Its standardized NEMA 17 frame size ensures it can be easily mounted and integrated into existing projects without the need for custom brackets.

This motor is the workhorse of the maker community, universally adopted as the go-to solution for 3D printers, where it controls the precise movement of the X, Y, and Z axes. It is also the perfect choice for CNC machines, robotic arms, and other automation systems where positional control is paramount. Whether you're building a new project or upgrading an existing one, this powerful and reliable NEMA 17 stepper motor provides the foundation for accurate and controlled motion.

The NEMA 17 Stepper Motor – 4.2kg·cm Torque is a compact, high-precision bipolar stepper motor widely used in 3D printers, CNC machines, laser engravers, and robotics. It offers accurate positioning, low vibration, and reliable torque ideal for tasks requiring smooth, repeatable linear or rotary motion.

With a standard 1.8° step angle and 4-wire configuration, it is compatible with most stepper drivers like A4988, DRV8825, and TMC2208, making it easy to integrate into a wide range of motion control systems.
