NEMA 17 Bipolar, 200 Steps, 42×38mm, 2.8V Stepper Motor - PL-2267
SY42STH38-1684A hybrid bipolar stepper motor with 1.8° step angle (200 step / revolution). Each phase draws 1.7A at 2.8 V, allowing a holding torque of 3.7 kg-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.
This motor also has 18cm Screw Shaft, 28cm Screw Shaft and 38cm Screw Shaft types.
