DC motors are used extensively in industrial variable speed applications because of most demanding speed-torque characteristics and are simple in controlling aspects. This paper presents a DC motor ...

This circuit takes advantage of the voltage drop across bridge rectifier diodes to produce a 5-position variable voltage supply to a DC fan or other small DC motor. It is not as efficient as a ...

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 ...

First note - I am a completely new to water cooling, this is the first build I've done. With GPU prices the way they are, I decided to try for an overclock vs a new GPU. Things are working well, and I ...

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 ...
