Steve,
The main reason that I changed the motor on my mill to 3 phase and a VFD wasn't the speed increase that came along with the change or the ability to change speeds on the fly without stopping. But because I had already lost one cheap chinese motor (I think to a lightening strike) and the motor that I replaced it with was of the same type.
I now have a motor that is a full rated 1.5 HP and not something that the Chinese dreamed up some number to put on it. If I could of ran the motor without having the VFD I probably would of went that direction but since I don't have a RPC or Rotary Phase Converter I went with the VFD which can be used in a static mode by simply setting the Frequency at 100 percent output.
