Yes, that is true. Ok for lightly loaded motors like my 3hp slot mortiser, but it would be self-defeating to run something like a widebelt off a static phase converter.Originally Posted by Erik Loza
It's easy to set up a rotary phase converter with a surplus 3 phase motor. I have about $400 in my 10hp rig. It makes sense for multiple machines that don't require adjustable speed. I have vfds on my lathe, edge sander and exhaust fan where the speed control is useful or necessary, but my slider and planer run off the rpc. Large vfds sem to be very expensive relative to rpcs.
