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 ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...

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 ...

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 ...

A friend asked me if I could develop a low-cost power driver for toy/hobby DC motors so he could use it with his microcontroller-based small electronics toy projects. Challenge accepted, the concept ...

Starting on Monday, September 19, and running through September 23, Design News will present the free course, DC Motor Controls with the RP2040 Pico. Each class runs an hour, beginning at 2:00 Eastern ...

For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the ...
