Sparkfun Stepper Motor - 125 oz.in (200 steps/rev, 600mm Wire)

For projects that demand more than the standard NEMA 17 can offer, the NEMA 23 stepper motor is the perfect upgrade. This robust motor delivers an impressive 125 oz.in (0.89 Nm) of holding torque, making it ideal for applications requiring more muscle, such as desktop CNC milling machines, large plotters, and sturdy robotic arms. With a step angle of 1.8° (200 steps per revolution), it provides the precision needed for intricate tasks.

This motor excels in applications like CNC routers, where its enhanced torque and power allow it to handle heavier gantries and tougher materials with ease. It's a popular choice for DIY CNC builders and those seeking a reliable replacement for their existing machine's axes. Compatible with well-known machines like the Shapeoko, it ensures seamless integration and optimal performance.

One of its standout features is the 600mm AWG22 wires, which simplify the wiring process for larger machines. This extra length often removes the need for additional splicing or extension cables, facilitating easier routing through drag chains to the controller board. This thoughtful design consideration saves time and reduces potential points of failure in your setup.

Despite its power, the motor maintains exceptional precision. When used with a modern microstepping driver, it delivers smooth motion and sub-millimeter positioning accuracy. This makes it an excellent choice for applications where both strength and finesse are required, without the complexity of encoders or feedback loops.
