Description

A stepper motor is a motor that takes one step at a time and moves in discrete steps. It is commonly used in applications requiring precise position control, such as 3D printers, laser cutters, and pick-and-place machines. This NEMA 17HS4401 bipolar stepper motor has a 1.8° step angle (200 steps/revolution) and a holding torque of 40N.cm (56oz.in). 

As the stepper motor draws a high current, 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 the 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 by designing a digital circuit.
