You can salvage some nice motors out of optical drives but they can be tricky to control. That’s because brushless DC motors require carefully timed signals used in a process called Electronic Speed ...

Two features are combined to build this electronic speed control (ESC) for brushed motors which includes a high-rate ESC with a brake and a high-rate 12A ESC with as receiver battery eliminator ...

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 ...
