Nema 17 stepper motor 1.8 degree 17HS4401S

Smaller bipolar (4-wire) NEMA17 stepper motor with 200 steps per revolution (1.8 degrees per step).

It’s not the most powerful NEMA17 motor, but it’s a little smaller, with a decent holding torque of 4000 g-cm (0.36 N-m, 56 oz-in).

It has a current rating of 1.7 A, which is ideally suited for small drivers such as the Allegro A4983 and A4988 and the Texas Instruments DRV8811, DRV8818 and DRV8825, as found in the Pololu and StepStick driver modules, as well as boards such as the gShield/grblShield and TinyG.

It also works very well with higher current drivers, such as those based on the TB6560 and TB6600. This motor is smaller but still powerful enough for Shapeoko and eShapeoko.
