PeggyHood2016 Posted January 30, 2016 Report Share Posted January 30, 2016 I have a de-airing pugmill that requires 3-phase power. Does anyone know if it is possible to convert it to something more common like 220? Link to comment Share on other sites More sharing options...
Marvin Horn Posted January 30, 2016 Report Share Posted January 30, 2016 If it isn't an integral mount motor it's no problem at all. Unfortunatelly most small pugmills use integral motors and may not be standard NEMA frames. Check the motor nameplate for the frame no and start there. Good Luck. Almost all vacuum pumps now appear to be non-NEMA propietary designs. Can't imagine why they used 3 phase on that small of a motor. Link to comment Share on other sites More sharing options...
Mark C. Posted January 30, 2016 Report Share Posted January 30, 2016 I think venco made 3 phase machines in Austrialia a lot. Not sure but would a phase converter work for you? Link to comment Share on other sites More sharing options...
PeggyHood2016 Posted January 31, 2016 Author Report Share Posted January 31, 2016 Thanks Marvin and Mark. It's quite large. I lot bigger than I wanted but got a real deal on it. Getting 3-phase power is problem than it's worth for just a pugmill. I was surprised to learn that it was three phase too. Link to comment Share on other sites More sharing options...
Mark C. Posted January 31, 2016 Report Share Posted January 31, 2016 A phase converter converts your 220 to three phase -Its just a device for one machine and lives next to that machine . I have a friend with a 3 phase large bandsaw (he does not have 3 phase in his neighborhood) he starts the phase converter at same time as band saw. Its a spend solution but it may be your only option. Check them out-the pug mill motor plate will help as well as calling the manufacture for details on solutions.

PeggyHood2016 Posted February 1, 2016 Author Report Share Posted February 1, 2016 Thanks Mark! a phase converter sounds like the answer! I did some quick research and have another question. Do you know if it would be a rotary or static converter? Thanks for all of your help, Peggy Link to comment Share on other sites More sharing options...
Mark C. Posted February 1, 2016 Report Share Posted February 1, 2016 No I do not-but I suggest talking to an electrician before you buy anything Link to comment Share on other sites More sharing options...

Bioman Posted February 10, 2016 Report Share Posted February 10, 2016 Should work, just make sure the voltages are tight; not all are and can hurt motors. Link to comment Share on other sites More sharing options...
neilestrick Posted February 10, 2016 Report Share Posted February 10, 2016 I have a de-airing pugmill that requires 3-phase power. Does anyone know if it is possible to convert it to something more common like 220? 220 has nothing to do with the phase. 220 is the voltage, not the phase. And if this is in a home, then you most likely have 240 volt service, not 220. 220 is a generic term, and doesn't exist in many places anymore. Common voltages in the US are 240 and 208. 208 is common in commercial properties, 240 is used in homes and some commercial spaces. 240 and 208 volts can be single or 3 phase, so you've got 4 possible combinations of voltage and phase. Your home has single phase, and your electric company may or may not be willing to give you 3 phase. It would probably be super expensive if they did. A phase converter would probably be the best solution. HERE is an article which explains the difference between types of converters. Talk to an electrician.

Mark C. Posted February 10, 2016 Report Share Posted February 10, 2016 I have a friend with huge 3 phase bandsaw He has a rotary converter-you start it with a rope on a handle like an old lawnmower Link to comment Share on other sites More sharing options...
Bioman Posted February 10, 2016 Report Share Posted February 10, 2016 Good article Neal. Don't use a static converter, too many down sides. An inverter, also called a Variable Frequency Drive could work and be much lower in cost than a Rotary. I found the folks at Factorymation.com to be helpful when I modified some of my woodworking equipment to use VFD's. What you need would require a 220/240 V single phase input which would give you 220/240 3 phase output (cost $150-$200 for the VFD). VFD's work by varying the frequency to deliver more or less averaged power and work best with motors as motors don't so much care. If your pug mill is newer it might have electronics; in which case a VFD might cause you serious issues. So ask them about your specifics before buying. Rotary converters can also cause issues with electronics as the wild leg voltage can vary a lot from the other two legs; unless you get a unit rated for Computer Numeric Control (CNC) in which case this is tighter.
