From Tony Rozendaal:
I recently disassembled a treadmill which contained a 1.75 HP 90VDC motor. I also have the control board and related wiring, including the input panel. I can demonstrate the motor running and change speeds up and down with the control panel.
This would be a great item for a tinkerer that wanted to convert a lathe, a bandsaw, a sander or some other belt driven item to variable speed. The control panel should be able to be used to understand the inputs into the control panel for run, stop, speed up and slow down, so a compact control center could be fabricated. There is also an incline motor included.
I am asking $125 for it all. Contact me at firstname.lastname@example.org.
