This dc motor speed-control circuit uses standard, available components; light impinging on two independent phototransistors establishes the motor's speed. Motor speed can be adjusted by the light ...

The circuit in the figure provides three levels of speed control for a dc motor, using a PC’s parallel port (LPT1). A C++ program performs the control functions by allowing the signals from the ...

In this exciting video, we dive into the world of controlling high voltage DC motors and the intricate process of designing a custom circuit for them. Join us as we explore the challenges and ...

This is a very cool electronic project to control dc loads using a very cheap and reliable design. This video also explains ...

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.

En route to getting the off-the-peg DC-51 motor speed controller to better suit my small milling machine, I had a go at working out what the circuit is. Approx circuit of DC-51 motor speed controller ...

Controlling a small dc motor without speed control sounds like a trivial task; a switch or a relay should suffice. However, several problems accompany this approach. For one, the switch, because of ...

It features adjustable maximum speed, minimum speed, current limit, I.R. compensation and acceleration, plus a quiet ...
