NEMA 23 is a high torque hybrid bipolar stepper motor
with a 2.3×2.3 inch faceplate. This motor has a step angle of 1.8 deg.,
this means that it has 200 steps per revolution and for every step it
will cover 1.8°. The motor has four colour coded wires (Black, Green,
Red & Blue) terminated with bare leads. Black and Green wire is
connected with one coil; Red and Blue is connected with other. This
motor can be controlled by two H-bridges but it is recommended to use a
stepper motor driver.
How to use NEMA 23 Stepper Motor
As mentioned above this stepper motor draws high current so instead of
controlling it directly using H-bridges, use an appropriately powerful
stepper motor driver. To know how to make this motor rotate we should
look into the coil diagram below.
As you can see from above diagram this motor has four wires in
different colours. This motor can be made to rotate only if the coils
are energized in a logical sequence. This logical sequence can be
programmed using a microcontroller or by designing a digital circuit.
