We have a German engineer in NZ who makes these converter for sale, have a look at his website, a lot of information , I think the limit is 10hp. Send him an email if you want, very helpful guy.

Define "portable". I have an RPC with a 10hp Baldor motor, it sits on a plywood platform that's about 2'x2', and I roll it around as needed. I believe I may have posted a picture in a thread last fall.

I have a 5hp rotary phase converter to run two 3 hp machines. They are only run one at a time. I wired the two machines into a simple on/off box. The converter is turned on first, then either machine. The box could easily have a plug on it to fit a 220 outlet. Been using this system for over 20 years - works great and is safe.
John - I mean portable enough just to be able to move it from 1 house to another every couple of years. Ideally portable means it is small and can be plugged into the wall...not fixed onto the electrical board on the side of a house. Could you share a pic of your setup?
My machine is only 1 HP and I wouldn't be using anything else at the same time.
A VFD weighs about a pound, you can't get more portable than that.

Evan:
I use an "RPC" (photo attached) which is semi-transportable. In other words, were I to move, it could be disconnected in less than an hour and ready for reinstall in about the same maybe a bit longer. It's used to power my bandsaw (220v), mortiser and grinder (440v via transformer), and combi (220v - slider, jointer, planer, shaper) ... so I need to plug and unplug when using different machines. That's a pia and I recently purchased additional outlets to alleviate that issue. I do plan on connecting the tools via conduit and outlets in the near future. That will make the whole setup less transportable. The numbers on the photo detail the parts. The RPC has proven super reliable but definitely contributes to the overall noise volume.
A VFD powers my 3hp 3-phase dust collector - I love it and have posted about that elsewhere in a forum here. Higher hp is very $$$.
1) Power into shop
2) Main Breaker in shop
3) 3-phase "fused" disconnect (slow 30 amp)
4) flex conduit for RPC (both in and out)
5) RPC
6) Outlet (L15-30R)
7) cord to tools with plug matching outlet

Anyone know of a good online store to get a VFD?
I have bought several from ebay. I typically buy Hitachi ones that are direct shipped from Hitachi USA with factory warrantys. Drives Warehouse and Factorymation are two online stores I have bought from. Driveswarehouse sells on ebay too and that was the last place I bought from.
For a 1hp machine you can buy a VFD that will drive that 1hp 3 phase motor on 115V (yes 115V!) single phase.

Glad its my shop I am responsible for - I only have to make me happy.
If you use a rpc can u still use the existing plug on the 3 phase machines you connect to it ?

As requested, pics of my mobile RPC:

That is a Contico "stool box" in there for perspective, with a Record #4 on it in one pic. Actual dimensions of the RPC are 24" long, 18" wide, 18" high.
