Who runs CNC CONTROL on a Rotary Converter?

I looked over the logan actuator page on rotary converter designed. It
was nice, but delt
only with motors. I want to run my 3-phase (input) servo amps from
single phase. They
are 10 amp DC output @ 150Vdc.

OK Guys... Which one of you runs your CNC control on a rotary single
phase to 3 phase
converter???? How do you size it??? I was going to go for 5Hp ( I
think that is just below
20 Amps @ 220V with 85% efficiency) Now if I "convert" that to 3 phase
I guess I get
only 33% of the current in each leg?? SO Can I get 6.6 amps ( 33% of 20
amps) at 220V 3 phase into my 3 phase transformer for the servo
amps??? Or is there a limit or losses in the rotary converter that limit
the current in the generated leg?
