Permanent magnet dc motors need a chunky inductor in series with them if they are fed from an SCR (thyristor) based mains power controller. It is (probably!) possible to safely interface an Arduino to ...

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 ...

This is a simple and very effective project circuit which helps to control the speed of a DC motor using pwm and microcontroller. In many applications, it is important to control the speed of DC motor ...

A plan to temporarily get the milling machine going, by hooking up an external speed controller, has turned into a semi-permanent solution. I ordered a ‘DC-51’ speed controller – an enclosed ...

Here are two simple 12V DC motor speed controllers that can be built for just a few dollars. Here are two simple 12V DC motor speed controllers that can be built for just a few dollars. They exploit ...
