Stepper Motor: Bipolar, 200 Steps/Rev, 42×38mm, 2.8V, 1.7 A/Phase

A NEMA 17 hybrid bipolar stepper motor with a 1.8° step angle (200 steps per revolution) and 3.7 kg-cm (51 oz-in) of holding torque. Each coil is rated 2.8 V / 1.68 A, so it is best driven by a current-limiting stepper driver running well above the rated coil voltage. The 5 mm D-shaft runs on two ball bearings, and four colour-coded 30 cm leads make wiring straightforward. Well suited to 3D printers, CNC machines and precision positioning.
