rotary phase converters, VFD

Hi
There has been a lot of discussion about phase converters and VFD drives.
I have had mixed results. I purchased a factory phase converter (10hp) that
was loud and had trouble with it overloading thermal breakers. I had a friend
put an Amp probe on it and we changed some compacitors around and it has
worked great every since. I have later made smaller converters with the help of
the article form "how to build a phase converter" the link is
http://www.metalwebnews.com/howto/ph-conv/ph-conv.html . I like VFD but the drive will run one
machine and then you have to buy another. I run an injection molder,CNC
mill,Cnc lathe and two manual machines all from the one converter. Good luck and
happy machining
