I have 2 treadmills that I am currently disassembling 1 is an older unit with a 1750 RPM 120/240 volt cap start cap run 1 1/2 Hp with a variable pitch drive pulley the other has the 130vdc 2hp magnet motor in it I don't know how much any of the electronics in it will be of any use as it sat out in the weather for several years but both machines have quite a bit of useable steel in them as well as the rollers and bearings so like butchering a hog I will try to save everything but the squeal.
the 1 1/2 Hp AC motor runs as I've already tested it too bad it wasn't a 5 or 6 hp as I need 1 of those to build a belt grinder which will wind up being a combination centerless grinder / flat face sander and pipe notching machine but I have a couple of 8 hp 3 ph motors that I was planning on making a 16 hp rotary phase converter out of
