Raspberry Pi Stepper Motor InterfaceĪlmost all advanced CNC Machines and Industrial Pick-n-Place Robots use Stepper Motors in them. With this technique, you can achieve even smaller resolution of 400 steps and a smoother operation.

Half Stepping is a technique where instead of energizing a single phase at a time, we will be use a combination of one phase and two phase energizing. to achieve a bit more precise angular positioning of the shaft, you can use a technique called “Half Stepping”. In order to increase the accuracy of the Stepper Motor i.e. So, for a complete 360 0 degree rotation, it will have a step count of 200. Typically, almost all commercially available Stepper Motors comes with a step angle of 1.8 0. The main advantage of a Stepper Motor over a Servo Motor is that complete rotation of the motor’s shaft is divided into steps and you can precisely position the Stepper Motor by carefully energizing the Motor Coils.Įven though there is no feedback mechanism like in a Servo Motor, a Stepper Motor with smaller step angles can provide very accurate angular positioning. For this project, I have chosen the L298N Motor Driver Module. So, choosing the driver module is up to you. Both these module work great with the 12V Stepper Motor. To drive this Stepper Motor, we need a motor driver module like L293D or L298N. In this project, I’ll be using a simple 12V Bipolar Stepper Motor.

Because, the driving techniques for each of these motor is different. whether it is a Unipolar Stepper Motor or a Bipolar Stepper Motor. It is important for you to identify your stepper motor i.e.

So, I suggest you to refer to that project once before continuing with the Raspberry Pi Stepper Motor Interface. I have already discussed about stepper motors, types of stepper motors, internal structure of a stepper motor and also how to design a stepper motor control circuit in STEPPER MOTOR CONTROL USING ARDUINO project. Stepper Motors can be categorized between Servo Motors and DC Motors as you can control the angular position of the shaft as well as rotate the shaft freely in either direction. If you remember the previous Raspberry Pi Tutorials, we have seen HOW TO CONTROL A DC MOTOR USING RASPBERRY PI and also HOW TO CONTROL A SERVO MOTOR USING RASPBERRY PI.
