NEMA 17 4 Kg-cm Bipolar Stepper Motor (17HS4401) 7 mm Shaft it fits into the boardA stepper motor is a motor that takes one step at a time and moves in discrete steps. It is commonly used in Applications requiring precise position control, such as 3D printers, laser cutters, and pick and place machines. This NEMA 17HS4401 bipolar stepper motor has a 1. 8 step angle (200 steps revolution) and a holding torque of 40N. cm (56oz. in). As the stepper motor draws a high current, instead of controlling it directly using H bridges, use an
