This small hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 800 mA at 4.3 V, allowing for a holding torque of 300 g-cm (4.2 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. These leads connect to the stepper motor through a removable JST-ZHR-5 connector. The motor can be controlled by a pair of suitable H-bridges (one for each coil), but we recommend using a bipolar stepper motor driver or one of our Tic Stepper Motor Controllers. In particular, the Tics make control easy because they support six different interfaces (USB, TTL serial, I²C, RC, analog voltages, and quadrature encoder) and are configurable over USB with our free configuration utility.

Our 4 mm universal mounting hub can be used to mount objects on the stepper motor’s 4 mm-diameter output shaft. For a slightly less powerful motor in the same NEMA size but a shorter length, consider Stepper Motor: Bipolar, 200 Steps/Rev, 20×30mm, 3.9V, 0.6 A/Phase. A comparison between these two motors can be seen in the image below.
