NEMA 23 Unipolar/Bipolar. 200 Steps. 57×41mm. 5.7V

 

SY57STH41-1006A hybrid stepper motor unipolar or bipolar stepper motor and has a 1.8° step angle (200 steps / revolution). Each phase draws 1A at 5.7V, allowing a holding torque of 4 kg-cm. The motor has six color-coded wires 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 midrange yellow and white wires can be disconnected (the red-blue pair provides access to one coil and the black-green pair provides access to the other coil). We recommend using bipolar stepper motor driver .

 

 

The diagram below shows the stepper motor dimensions in mm Length is 41 mm. The output D-shaft is 20.6 mm long and 6.35 mm in diameter, with a 0.5 mm flattened cross section will help you mount this stepper motor in your project.

 

Stepper motors are often used in a variety of applications where precise position control is desired and the cost or complexity of a feedback control system is not warranted. A few applications where stepper motors are often found:
