A NEMA 17 stepper motor is a stepper motor with a 1.7 x 1.7 inch (42.3 x 42.3 mm) faceplate. The NEMA 17 is larger and generally heavier than for example a NEMA 14, but this also means it has more room to put a higher torque. However, its size is not an indication of its power. The motor conveniently connects via a typical 6 pin JST.
