This bipolar stepper motor with planet gear box (gear ratio: 5.18) uses a standard 8mm-diameter D type output shaft, and has a 1.8° step angle (200 steps/revolution). Each phase draws 1.0 A at 3.4 V, allowing for a holding torque of 18kg-cm (176N-cm) (200rpm). The motor has a body dimension of 42mm square and 40mm in length, while the planet gear box is 36mm in diameter and 27mm in length. 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 easily mounted with 4 M3 threaded holes and can be controlled with the Dual Bipolar Stepper Motor Shield for Arduino (DRV8825).
Notice: please carefully confirm techical details (torque, dimension, mounting, etc) for your project(s) before purchasing.
