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 ...

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 ...

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 ...

Industrial applications use direct current motors because the speed-torque relationship can be varied to almost any useful form -- for both motor and regeneration applications in either direction of ...

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 ...
