I wonder, though. In modern machinery, a whole lot of them are run by VFCs as a matter of
normal practice. That includes very large ones; I recently read an article about
replacing large DC motors by AC VFC-powered ones. I forgot exactly how large, but I'm
pretty sure they were over 1000 hp, driving factory machinery, perhaps rolling mills or
stuff like that.
I wouldn't run my $100 little VFC in production, but I expect that the more expensive
ones from serious companies like Yaskawa or Allen-Bradley will do just fine.
