Stepper Motor: Unipolar/Bipolar, 200 Steps/Rev, 57×56mm, 3.6V, 2

Description

This high-torque hybrid stepping motor has a 1.8° step angle (200 steps/revolution). Each phase draws 2 A at 3.6 V, allowing for a holding torque of 9 kg-cm (125 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. NEMA 23 stepper motor (item #1475) mounted with a steel L-bracket for NEMA 23 stepper motors. Our 1/4? universal mounting hub and 1/4? scooter wheel adapter can be used to mount objects on the stepper motor’s 1/4?-diameter output shaft, and we carry a NEMA 23 steel bracket for securely mounting this stepper motor to a flat surface (the picture above shows this bracket being used with a taller NEMA 23 stepper motor). 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 and 1/4? scooter wheel adapter . The inside of a bipolar stepper motor. 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 unwarranted. Here are a few applications where stepper motors are often found:
