A brief introduction to Stepper Motor As mentioned earlier, a Stepper Motor is a type of DC Motor that rotates in discrete steps. Due to their unique design, stepper motors can be controlled for precise positioning without any feedback. A typical stepper motor has multiple coils that are divided into phases.

Basically, there are three types of stepper motors: Variable Reluctance (VR) Stepper Motors, Permanent Magnet (PM) Stepper Motors and Hybrid Stepper Motors. Based on the winding of the stator, stepper motors can also be classified as Bipolar Stepper Motors and Unipolar Stepper Motors. We will not go into the details of the types of stepper motors but it is important to identify whether your stepper motor is a bipolar or unipolar one.
This is because, the driving method for each of these stepper motors is different from the other. For instance, the driver circuit of a unipolar stepper motor can be implemented with simple transistor based circuit or a Darlington Transistor IC like ULN2003A. Install Flash On Linux Fedora.
But in case of a bipolar stepper motor, we need to implement an H – bridge type driver like L293D Motor Driver IC. The following image shows a bipolar stepper motor, a 6 – wire unipolar stepper motor and a 5 – wire unipolar stepper motor.
The most common step angle or step count for stepper motors is 1.8 0 or 200 steps (both of them are same as 1.8 0 x 200 = 360 0). How to Design Stepper Motor Control Circuit? In this project, we have used a bipolar stepper motor. Hence, we used the Motor Driver IC L293D, which is an H – bridge type driver. Since it is a bipolar stepper motor, there are only 4 wires we need to connect. So, connect the two wires from one coil to outputs 1 and 2 of L293D and the other two wires from second coil to outputs 3 and 4.

The 4 inputs of the L293D Motor Diver IC are given from Arduino UNO. So connect them to any of the 4 digital I/O pins (here, we connected them to pins 2, 3, 4 and 5 of Arduino UNO). Understand the power requirements of your stepper motor and provide necessary power supply. Wrong power supply would permanently damage the motor. The control of steps is done with the help of computer using serial monitor. So, make sure that the RX and TX pins of the Arduino are not used as digital I/O. Alternatively, we can control the steps or rotation of the motor with the help of analog input via a potentiometer.
