Hi all, I just hooked up a used, Snyder brand, Rotary Phase Converter to my newly acquired lathe (more on that soon). It works but makes excessive noise & vibration, especially when running under no load condition. It sounds like its vibrating at 60hz so my thought is its electrical in nature, not mechanical. It is very loud at start up but quiets down noticeably when the lathe motor is running. The converter came pre-wired with a switch and a 3 phase twist-lock outlet, so all I had to do was hook the mains to it, thus I think it is wired correctly. Has anyone had a similar issue? Could it be bad capacitors?
