I was just looking on the Drives Warehouse website to see if they had any of
the 5HP Spedestar VFDs in stock, and I punched in the worng search
parameter. I found a pleasant surprise. They are listing Spedestar 1ph -
3ph VFDs upto 30HP now. Those big ones aren't cheap (not outrageously
expensive either), but it opens up a world of options in used equipment for
those of us running home shops or for folks running small shops that don't
have 3 phase power other than buying or building a big noisy rotary phase
converter.
The last time I looked the largest I found for 1ph-3ph was 5HP.
