Stepper Motors are fantastic little tools that are capable of turning very precisely to specific angles, with many of the different models offering either 200 or 400 steps per revolution. This rating essentially tells you how many movements the motor can take before turning a full revolution – meaning that it has 200 or 400 different specific locations to which it can turn. This translates to precision accuracy, as a stepper motor driver can make the motor turn exactly halfway, a quarter of the way, or any of the 200 or 400 steps that it takes to do a full revolution.

This NEMA 23 is a hybrid bipolar stepper motor that operates at 2A and 2.6V to provide a holding torque of 9kg-cm, which is ideal for machines like CNC or milling machines. While they used to be used in 3D Printing applications, NEMA 17 Stepper Motors have replaced these motors in most of modern builds and models. As such, these NEMA 23 motors are purchased mostly for other types of machines, due to their larger size and higher holding torque.

Typical Applications for the NEMA 23 Stepper Motor (2A, 9kg-cm):

Due to the size and power of these NEMA 23 Stepper Motors, many Makers choose these to operate drills and other rotational components requiring high torque at relatively low speeds. And while these motors can reach reasonable speeds, they can’t compare to motors that have been designed for high speed applications. However, on the other hand, high speed motors seldom offer a torque as high as these motors do, making them a valuable addition to almost any tinkerer’s workshop.
