This 8051 microcontroller-based control circuit adjusts the speed of a small permanent-magnet dc motor via photosensors (see the figure). The circuit can find applications in light-tracking systems ...

This project demonstrates how to control the speed of a DC motor using PWM signals generated by the LPC1768 microcontroller. A potentiometer is used as an analog input to vary the speed, which is read ...

DC motors are used extensively in industrial variable speed applications because of most demanding speed-torque characteristics and are simple in controlling aspects. This paper presents a DC motor ...

We use DC fans in many systems in our day to day life. For example, CPU fans, fume extinguishers and many more appliances which we make use of, are operated by DC. This is a project used to control ...

To study the working principles of an Electronic Speed Controller (ESC), Brushless DC (BLDC), and other components in an electric scooter. To design and develop an Electronic Speed Controller (ESC) ...

Recently, I found an interesting fan motor module in a web shop and grabbed a couple of them for nothing. At the heart of the module is an eight-pin L9110 DC motor control chip from ASIC (www.asic.net ...
