Stepper Motor: Bipolar, 200 Steps/Rev, 57A—56mm, 2.5V, 2.8 A/Phase
This NEMA 23-size hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 2.8 A at 2.5 V, allowing for a holding torque of 13 kg-cm (180 oz-in).

This high-torque hybrid bipolar stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 2.8 A at 2.5 V, allowing for a holding torque of 13 kg-cm (180 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.
Our 1/4" universal mounting hub can be used to mount objects on the stepper motor’s 1/4"-diameter output shaft.
More specifications are available in the datasheet (49k pdf).
The following diagram shows the stepper motor dimensions in mm. The output D-shaft has a 0.25" (6.35 mm) diameter with a section that is flattened by 0.5 mm (note: the diagram below incorrectly lists this flattened width as 6 mm when it is really 5.85 mm). This shaft works with our 1/4" universal mounting hub.
