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 ...

The circuit illustrates the operation of solid state switches as it controls the movement and the direction of the motor as denoted by the LED. DC Motor – a single coil apparatus used to convert ...

An integrated motor drive power IC is space and power efficient with an architecture scalable to higher current levels. A fully protected dual high-side MOSFET power switch has an entire H-bridge ...

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 ...
