Unipolar/Bipolar Hybrid Stepper Motor 4V 1.2A/Phase 200 Step

Stepper motors are generally used in a variety of applications where precise position control is desirable and the cost or complexity of a feedback control system is not reasonable. This hybrid stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 1.2A at 4VDC, allowing for a holding torque of 3.2 kg-cm (44 oz-in). The motor has six color-coded wires terminated with bare leads allowing it to be controlled by both unipolar and bipolar stepper motor drivers. When used with a unipolar stepper motor driver, all six leads are used. When used with a bipolar stepper driver, the center-tap yellow and white wires can be left unconnected (the red-blue pair for one coil and the black-green pair for the other coil). We recommend using it as a bipolar stepper motor.
