You can get a VFD for less than 200 - 250.

Hey Bob,

While from a technology standpoint it looks like a VFD is the way to
go I'm concerned about their operational requirements. For example
one site states its units require less than 90% humidity for storage
and operation. We are on the humid Texas Gulf Coast. Humidity is
extremely high although I don't remember what percentage the
weatherman normally quotes.

I'm looking at one that is 10HP. If I go down this road I might as
well buy one big enough to operate some other 3 phase tools I bought
long ago and never put to any use.

VFDs are to be used on a SINGLE machine. Now you can use them to run a
bunch of machines, but only ONE AT A TIME!!!!
