Design a Unipolar Stepper Motor Controller/Driver and Circuit Diagram
Design a Unipolar Stepper Motor Controller/Driver and Circuit Diagram - Stepper motors have two types, unipolar and bipolar. In unipolar motors the current flows one direction through any Astable Oscillator Output Used as Clock-Pulse Generator Circuit Diagramgiven motor coil while motor need controllers to adjust position and speed.
Then you will need a motor driver to amplify a controller’s low output current to a larger current that is required by a motor. Below is an article that describe you about how to design a unipolar stepper motor controller/driver.
You will be taken into sections that will describe you on unipolar stepper motor and BJT transistors, learn how to use a universal shift register, and put it altogether to design unipolar stepper motor driver (using a Jameco 15 V unipolar stepper motor).
Within the article, there are explanation about The advantages and disadvantages between unipolar, bipolar and DC motors, Ways of energizing stepper motor coils in the proper sequence, Variable Speed Stepper Motor Drive, and Microcontroller Stepper Motor Control.
Also, there are Diagram of Unipolar Stepper Motor, Schematic of Unipolar Stepper Motor, Universal Shift Register (74HC194) Pin-Out, Operation of Universal Shift Register, Schematic of Stepper Motor
Driver Circuit with LED circuit added, Output Circuit Modification, Motor Voltage Connection, and Astable Oscillator Output Used as Clock-Pulse Generator circuit diagram.
