This hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 1 A at 2.7 V, allowing for a holding torque of 1.4 g-cm (20 oz-in). The motor has four color-coded wires terminated with bare leads: black and green connect to one coil; red and blue connect to the other. It can be controlled by a pair of suitable H-bridges (one for each coil), but we recommend using a bipolar stepper motor driver.

Our 5 mm universal mounting hub can be used to mount objects on the stepper motor’s 5 mm-diameter output shaft.
