Re: [CAD_CAM_EDM_DRO] 3-Phase motor running from Single Phase Supply ?

This is not exactly true! Try running about 5 of those 5HP motors under
load at the same time with that 7.5 HP phase converter. Even the
manufacturers of commercial phase converters will tell you there is a limit
to how much load can be applied to any given phase converter. If there
wasn't a limit, the manufactures would only build one size...make it small
as possible and then sell it for the maxium price.
