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 ...

Reversing Motor Circuits provides a comprehensive overview of the various means used to reverse electric motors. Motor control circuits use various control devices to change the direction in which a ...

The 130 Series motor-reversing control uses zero-speed detect and solid-state dynamic braking circuits that eliminate contact arcing and failed braking problems. The zero-speed detect circuit also ...

The DC motor is widely used in the field of servo automation and robotics. The operating principle of an electric motor is based on the interaction of two magnetic fields that attract and repel each ...

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 ...

I have been trying to fix a little old milling machine I bought (and here), and needed a replacement motor controller. It is a Clarke DCM10, a variant of Sieg’s X1, sometimes knows as a ‘micro mill’.
