1/7/2023 0 Comments H bridge gate driver circuitControlling the speed of the dc motor can be done in different ways like using a potentiometer and also by a controlled current to the armature. Here we design a simple DC motor speed control PWM circuit by using IC 555 and motor driver IC L293D. It can control both the speed and spinning direction of two DC motors. Now one of the easiest and most inexpensive ways to control DC motors is to use L293D Motor Driver IC. Like if you are planning on assembling a robot, you will eventually need a DC motor controlling circuit. The DC Motor is used in many applications, and some applications require speed control of the DC motor sometimes it requires rotation direction control. It works on the principle of Lorentz force by which the current-carrying conductor in a magnetic field experiences a force hence the conductor moves in the direction of force called Lorentz force. In this tutorial, we are going to make a “DC Motor Speed Control PWM circuit”.Ī DC motor is an electro-mechanical device that converts direct current into mechanical energy using the rotation of a shaft.
