The stepper motor used in this project is a Bipolar PMH (Permanent Magnet Hybrid) type Stepper Motor. The working of the project is explained here.

Working of the ProjectĪ simple Stepper Motor Control using Arduino UNO and L293D Motor Driver IC is designed in this project. Alternatively, we can control the steps or rotation of the motor with the help of analog input via a potentiometer. So, make sure that the RX and TX pins of the Arduino are not used as digital I/O.

The control of steps is done with the help of computer using serial monitor. Wrong power supply would permanently damage the motor. Understand the power requirements of your stepper motor and provide necessary power supply. 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). The 4 inputs of the L293D Motor Diver IC are given from Arduino UNO. 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. Since it is a bipolar stepper motor, there are only 4 wires we need to connect. Hence, we used the Motor Driver IC L293D, which is an H – bridge type driver. In this project, we have used a bipolar stepper motor. How to Design Stepper Motor Control Circuit? 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). The following image shows a bipolar stepper motor, a 6 – wire unipolar stepper motor and a 5 – wire unipolar stepper motor. But in case of a bipolar stepper motor, we need to implement an H – bridge type driver like L293D Motor Driver IC. This is because, the driving method for each of these stepper motors is different from the other.įor instance, the driver circuit of a unipolar stepper motor can be implemented with simple transistor based circuit or a Darlington Transistor IC like ULN2003A. 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. Based on the winding of the stator, stepper motors can also be classified as Bipolar Stepper Motors and Unipolar Stepper Motors. When each phase is energised in sequence, the rotor of the stepper motor rotates in steps.īasically, there are three types of stepper motors: Variable Reluctance (VR) Stepper Motors, Permanent Magnet (PM) Stepper Motors and Hybrid Stepper Motors. Due to their unique design, stepper motors can be controlled for precise positioning without any feedback.Ī typical stepper motor has multiple coils that are divided into phases.
