Without the technical aspects.
You can buy from several different mfg's a unit that "tricks" 220V single
phase into three phase. The cheapest unit, less than $200, is a box with
some capacitors. The motor runs fine, but only puts out 2/3 rated hp.
The better setup uses a similar box, but also includes what looks like a
5hp electric motor. Generates it's own third phase. Even the smallest
one will run 5 or 6 motors at the same time. Runs about $600 or so. If
you can wire an outlet or circuit, you can wire this unit.
Once you have one, you can than buy 3 ph anything. Real tools like my
bridgeport, but cheap because today's machine shops have all gone CNC.
Good luck.
