Stepper Motor: Bipolar, 200 Steps/Rev, 35x26mm, 7.4V, 280mA

This hybrid bipolar stepping motor has a 1.8 ° step angle (200 steps/revolution). Each phase draws 280 mA at 7.4 V, allowing for a holding torque of 650 g-cm (9 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 5mm universal mounting hub can be used to mount objects on the stepper motor’s 5mm-diameter output shaft.
