Overview

This tiny bipolar stepping motor from Sanyo has a 1.8° step angle (200 steps/revolution). Each phase draws 300 mA at 6.3 V, allowing for a holding torque of 66 g-cm (0.92 oz-in). The motor has four color-coded wires terminated with bare leads: red and yellow connect to one coil; orange 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. It is available with a single shaft or double shaft.

Our 4mm universal mounting hub can be used to mount objects on the stepper motor˙s 4mm-diameter output shaft.
