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 ...

Traditionally, DC motors have been used in precise speed control applications because of their ability to provide acceleration and deceleration from a dead stop position to full speed fairly easily.

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.

Approx circuit of DC-51 motor speed controller (D6 and D8 are the wrong way around, and there may be more errors) And the more I looked at the circuit, the more I liked the speed controller. Update ...

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 ...
