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 ...

This is a very cool electronic project to control dc loads using a very cheap and reliable design. This video also explains ...

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 circuit in the figure provides three levels of speed control for a dc motor, using a PC’s parallel port (LPT1). A C++ program performs the control functions by allowing the signals from the PC ...

The compact electric hydraulic actuator (EHA) from Parker Hannifin’s Oildyne Div., New Hope, Minn. (www.parker.com), combines all the traditional components of an electrohydraulic linear actuator in a ...

It may have been designed for a sewing machine, but [Haris Andrianakis] found his imported DC brushed motor was more than up to the challenge of powering his mini lathe. Of course there’s always room ...

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’.
