Stepper motor: unipolar/bipolar, 200 steps/revolution, 57 x 56 mm, 7.4 V, 1 A/phase

This high-torque hybrid stepper motor has a step angle of 1.8° (200 steps/revolution). Each phase draws 1 A at 7.4 V, providing a holding torque of 9 kg-cm (125 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.

A 6.35 mm universal mounting hub allows objects to be attached to the 6.35 mm output shaft of the stepper motor.

Dimensions:

The following illustration shows the dimensions of the stepper motor in mm. The output shaft has a diameter of 0.25" (6.35 mm) with a 0.5 mm flattened section (Note: In the illustration below, this flattened width is incorrectly shown as 6 mm; it is actually 5.85 mm). This shaft is compatible with our 1/4" universal mounting hub.
