Stepper motor: unipolar/bipolar, 200 steps/revolution, 42 x 48 mm, 4 V, 1200 mA

This hybrid stepper motor has a step angle of 1.8° (200 steps/revolution). Each phase draws 1.2 A at 4 V, providing a holding torque of 3.2 kg-cm (44 oz-in). The motor features six color-coded wires with bare leads, allowing it to be driven by both unipolar and bipolar stepper motor drivers. When used with a unipolar driver, all six wires are used. When used with a bipolar driver, the yellow and white wires in the center can remain unconnected (the red-blue pair provides access to one coil, and the black-green pair provides access to the other). We recommend using it as a bipolar stepper motor.
