A simple controller for a dc treadmill motor?
I have a United Technologies dc motor, 2.5 hp @ 120VDC, but no controller. It has a red & black wire, plus 2 blue wires. The black goes through a choke coil. Anybody have a breadboard type of design for a speed controller with hookup instructions? I can solder, follow a schematic, and wire a house, but am not up on electronics. Last radio I built was in the mid 50's, so I probably need more than usual specifics. Thanks for any help you can offer. Ed B
