NEMA 14 Bipolar, 200 Steps, 35×26mm, 7.4V Stepper Motor - PL-1207
SY35ST26-0284A hybrid bipolar stepper motor with 1.8° step angle (200 step / revolution). Each phase draws 280 mA at 7.4 V, allowing a holding torque of 650 g-cm. The motor has four color-coded wires terminated with bare ends: black and green connect to a coil; red and blue are connected together. The motor can be controlled with a pair of suitable H-bridges (one for each coil), but bipolar
stepper motor driver.
