Hi All,
I'm not going to pretend to know anything about electronics. My hobbies revolve around motorcycles and cars ... so I could really use some help.
I've been restoring an 1944 metal lathe that currently has a 3/4 hp AC motor. I would like to be able to use lower spindle RPMs speeds without engaging the rattly back gear (and to be able to reverse the spindle occasionally). To that end, I've picked up a treadmill. It's PM DC motor is 90V, 4800 RPM, 15A.
I have read just about everything I can find here and elsewhere on the web, but I'm still confused. Here's a KB KBIC-125 controller I think might work (specs here) -- especially if I use the auxiliary heat sink -- but I wonder if you knowledgeable folks could confirm this. The treadmill was advertised (in 1994) as "2.5HP", which exceeds the maximum spec for the controller, but that may not be an issue -- am I right? Also, what resistance "horsepower resistor" should I get for that motor?
Thanks a million for any help!
