NEMA 11 Bipolar, 200 Steps, 28×45mm, 4.5V Stepper Motor - PL-1206
SY28STH45-0674A hybrid bipolar stepper motor with 1.8° step angle (200 step / revolution). Each phase draws 670 mA at 4.5 V, allowing a holding torque of 950 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.
