Stepper Motors are wonderful little gadgets, with each offering a distinct profile of strengths in terms of torque, speeds, rotational accuracy and a few other defining factors. This, while it certainly makes them small marvels of modern engineering, means that you can’t simply replace a stepper motor with any other model, as you need to try to match the previous motor as closely as possible to enjoy the same effects.

This is why we strive to provide as many different stepper motor models as possible, such as this NEMA 17 Stepper Motor, which offers a relatively beefy 4.5kgf-cm by drawing 1.68A per phase. This makes it a great choice for quite a wide range of applications. However, if you’re looking for even more accuracy and a higher step count per revolution, we do also offer 0.9° Versions of these stepper motors as well, which are typically used for extreme-precision applications like 3D Printing.

So, if you’re looking for a reliable and powerful stepper for general applications, without extreme precision, then these 1.8° NEMA 17 Steppers are an excellent choice that both easy to use, very affordable and surprisingly powerful for their size.
