I will go to them and see what they can supply. The good part is to deal face to face. The price we got on the phone is $ 515.00 for 3 hp. which sounds good. This is not a hurry up deal I am working at it as I have time. If you can find an old 3-phase motor (slightly larger HP rating than your motor)that is delta wound all you need to do is wire it to 220 single phase & also wire it to your 3-phase,get a 110 volt motor & hook up a belt to this 3-phase motor get the 1 running to spin the 3-phase(convertor motor) & then turn the 220v single on & shut the 110v starter motor off & as long as the 3-phase Is spinning it'll put out 3-phase.Usually you can find old 3-phase motors pretty cheap.I just happened to buy a trailer that had a new one in it(3HP) & used it. It's run our Bridgeport mill for years on this 3 phase convertor I made.There is some directions on the web.It is very simple though.

Members Hillbilly tim Posted March 24, 2017 Members Report Posted March 24, 2017 (edited) Check these folks out. They sell manufactures NOS and overstock inventory. They have phase convertors and offer technical advice too. I have purchased many different items from them for 20 plus years. https://www.surpluscenter.com/Electrical/3-Phase-Motors/Phase-Converters/ Bro. Timothy Edited March 24, 2017 by Hillbilly tim Quote
