Charles, from my (German) point of view, the power at 480 Volt three phase times 5 Amperes (each) times sqrt. of 3 makes some 15 HP. That's what the machine label wold mean to me at the power supply standards in our house. look at the power label right at the spindle motors body. Peter Am

I resold something very similar. It is a great retrofit candidate. I also have some parts for those machines. It will not be a fast machine, just like my Interact is not a fast machine, but it is a great machine and a very nice retrofit experience, DC servos, etc. On Sat, Mar 29, 2014 at 7:45

Your math is way off. A three phase motor uses about 1.75 amps per HP at 480v. So it is a 3 HP machine. On Sun, Mar 30, 2014 at 8:53 AM, Peter Blodow p.blo...@dreki.de wrote: Charles, from my (German) point of view, the power at 480 Volt three phase times 5 Amperes (each) times sqrt. of 3

I'd be very surprised if the motor was 480 volts only. They are almost always at least dual voltage. To me, the big things to look for are, not much abuse, very little mechanical slop in anything, good motors, working drives if possible or if not, then reasonably priced drives available, a
