Three Phase Pugmill
Hi! I'm a potter who acquired a used deairing pugmill designed for
three phase power, which I don't have and don't plan to get. Can a static converter succesfully run it on 220? Or should I switch out the motor to run on ordinary house current? If needed, I can post HP, model, etc. of the machine. It has two motors, one to turn the two screws to mix the clay, and one to run the vacuam. Thanks! Sparfish Studio |

So yes please do post the motor information. And a 3 phase converter should do well for you if it is necessary. Bob AZ |

Three Phase Pugmill
Static phase converters aren't designed to handle multiple motors very well.
A rotary phase converter will be better suited for the job, but can be quite expensive. Probably the first thing that you should do is to price replacement motors and then decide whether new motors or a rotary phase converter is the best option. Of course, if you go with a phase converter, then you will be able to acquire additional 3 phase equipment and run one of them at a time. Charley "C. A. Sanger" wrote in message ... Hi!

Three Phase Pugmill
At the Vegas AWFS show I had a long conversation with a guy who was
selling rotatry converters. I mentioned "running" one at a time and he assured me it was just "starting" one at a time that was the limitation. He said the converter can feed multile machines at the same time but the start-up draw requirements only allow one to start at a time. I've seen from Craigs list and other places that you can often get great prices on older 3 phase equipment because the "demand" side of the equation is minimal with not so many people that have 3 phase so the prices are low. This is especially true for much older machines because most established companies (ie those with 3 phase in their factory) aren't interested in buying old equipment. So a converter could be a great investment over time. On Aug 2, 7:56 am, "Charley" wrote: Static phase converters aren't designed to handle multiple motors very well.
