I bought the Mother of All Drill Presses at a surplus sale where I work. This beast has with multiple speeds, auto-feed, adjustable knee-type table, the works - must weigh 900 pounds!
Only problem is: the 1.5 hp spindle motor runs on 460 volts. I had in mind using a VFD that would take 230 VAC in and produce 460 three phase out, but I haven't found one yet that will do that. Any suggestions would be appreciated.
The only other alternative I see is to replace the spindle motor. It's a Reuland similar to what I've seen on mills and other machines, anyone tried doing this?
I know there are VFDs that take 120 single phase in in and put out 230 three phase, so it should be possible to do the same with 230/460. (Hopefully!)
Thanks,
Bob
