This is simply how a DC motor is actually working. Which in turns applies an inversed torque of each side of the coil resulting in a reverse direction in the rotation. Reversing the direction of current flow in the coil translates to an inversion in the direction of the rotor’s magnetic field. ![]() Which in turns causes the coil assembly (Rotor) to rotate, as each coil is pushed away from the like-pole and attracted to the unlike-pole of the stator. The current generates magnetic fields in the coils. 12v) image source (Renesas Electronics) Įlectrical current is passing through coils that are arranged within a fixed magnetic field (Stator). A typical DC motor will have the following features: Component Name Buy On 1 PIC16F877A Add 1 BreadBoard Add 1 DC Motor 12v 1000RPM Add 5 Push Buttons Add 1 Resistors Kit Add Add 1 Capacitors Kit Add Add 1 Jumper Wires Pack Add Add 1 L293D DC Motor Driver Add Add 1 LM7805 Voltage Regulator (5v) Add 1 Crystal Oscillator Add 1 PICkit2 or 3 Programmer Add 2 9v Battery or DC Power Supply Add Add AddĭC Motors are very simple rotary actuators that transform electrical energy into a mechanical rotation at a specific torque. We’ll finally draw in some concluding remarks. We’ll develop the required firmware code in order to control a DC motor as a practical Lab at the end of this tutorial. You’ll also get familiar with the required hardware driving circuitry. You’ll learn how DC motors work, How to control both the speed & direction of a DC motor. ![]() In this tutorial, we’ll be doing DC motor speed control with PIC microcontrollers using PWM and L293D motor driver H-bridge IC. ![]() Previous Tutorial Tutorial 16 Next Tutorial DC Motor Speed Control With PIC And L293D IC | PWM Introductory Level ★☆☆☆☆
