Assume that I have in front of the above referenced options. I can
pick only one - a VFD, a (rotary) Phase Converter or straight 3-phase
power for the 3-phase 16" Rockwell RAS I picked up for $300. In the
long run, which will cost less to own and operate over time? Assume
the 5hp VFD is $250 and the 5hp converter is $400. Am I likely to
spend a lot more money on power if I have to spring for 3-phase direct?

ask your electric company. policies are very local- some places
they'll refuse to hook it up to a residential building, other places
there is a hookup fee, other places they will set you up for free.

how it will compare per unit cost I have no idea.



Manintenance issues with the VFD and converter relative to 3-phase
power - and to each other?

Thanks, and I'm googling too.
