In this article we discuss a Full bridge or H bridge based Bidirectional motor controller circuit using the 4 opamps from the IC LM324. Introduction Generally, mechanical switches are accustomed to adjust the direction of rotation of a DC motor. Adjusting the polarity of the utilized voltage and the motor rotates the opposite direction! On […]
Electronic Speed Controller
These speed controller modules may have different configurations and specifications depending on which type of motors is being used.
As you will find under the following articles that for brushed motors the PWM control is applied to the armature of the motor, while industrial induction type of motors working with electromagnetic field winding may have controller adjusting the the magnetic flux of the field winding to regulate its speed.
For unique cases such as for brushless motors the control is achieved by implementing a calculated switching of the involved multiple sets of winding position across a fixed magnet rotor.
More on such concepts can be studied by referring to the following in-depth analysis.
3 easy to build speed controller circuits for DC motors are presented here, one using Mosfet IRF540, second using IC 555 and the third concept with IC 556 featuring torque processing. Design#1: Mosfet based Motor Speed Controller A very cool and easy DC motor speed controller could be build using a just a single mosfet, […]
In this article we will try to understand how scalar control algorithm is implemented for controlling induction motor speed with relatively straightforward calculations, and yet achieve a reasonably good linearly variable speed control of the motor. Reports from many top market analysis reveal that induction motors are the most popular when it comes to handling […]
In this post we are going to learn about L298N dual H-bridge DC motor driver module which can be used to drive brushed DC motors and stepper motors with microcontrollers and ICs. Overview Modular circuit boards are best time savior for electronics designers which also reduce the prototyping errors. This is mostly preferred by programmers […]
In this post we will learn how to control servo motors using a joystick and Arduino. We will see overview about joystick, its pins, its construction and working. We will be extracting useful data from the joy stick which will be base for controlling the servo motors. Introduction The motto of this article is not […]
In this project we are going to run a unipolar stepper motor using 555 timer. Apart from 555 timer we also need IC CD 4017 which is a decade counter IC. By Ankit Negi Any unipolar motor can be connected to this circuit for performing specific task, though you need to do some small changes […]
