Stepper Motor: Unipolar/Bipolar, 200 Steps/Rev, 57x41mm, 5.7V, 1 A/Phase

This high-torque hybrid stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 1 A at 5.7 V, allowing for a holding torque of 3.9 kg-cm (54 oz-in). The motor has six color-coded wires terminated with bare leads that allow 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 motor driver, the center-tap yellow and white wires can be left disconnected (the red-blue pair gives access to one coil and the black-green pair gives access to the other coil). We recommend using it as a bipolar stepper motor.

The following diagram shows the stepper motor dimensions in mm. The output shaft has a 0.25? (6.3 mm) diameter. Though not shown in the diagram, the output is a D-shaft with a section that is flattened by 0.5 mm.
