This file type includes high resolution graphics and schematics when applicable. This 8051 microcontroller-based control circuit adjusts the speed of a small permanent-magnet dc motor via photosensors ...

With the help of this DC drill speed controller circuit you can control the number of revolutions of your drilling machine. A mini-drill machine is always needed in drilling the printed circuit board.

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

The project is designed to control the speed of a DC motor using an 8051 series microcontroller with android application device. The speed of DC motor is directly proportional to the voltage applied ...
