Stepper Motor: Bipolar, 200 Steps/Rev, 28×45mm, 4.5V, 0.67 A/Phase
POL-1206This NEMA 11-size hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 670 mA at 4.5 V, allowing for a holding torque of 950 g-cm (13 oz-in).
This hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 670 mA at 4.5 V, allowing for a holding torque of 950 g-cm (13 oz-in). 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 controlled by a pair of suitable H-bridges (one for each coil), but we recommend using a bipolar stepper motor driver.
