I know a few people that are using rotary converters, some home built, for various CNC machines, especially if you have a regular induction motor for spindle, I am using one to run two mills that have VFD's on the spindle and single phase for the control and servo's.
I think that guy was spinning you a $10,000 line!!
Are your servo's 1ph? The only reservation I would say is if they are older 3ph SCR DC drives that fire directly across the line, If they are I would put a three phase line filter before the machine, manufacturers like Hammond make them.
