I think most home shops use phase converters, either rotary phase converters or variable frequency drives. With those you can create a third phase to run machines that need it, although obviously you won't have as much power available to you.
And of course, an alternatives is to have a battery bank as well with inverters - which means you can get your amps - but only if you're not running 24/7. You'd have to let the grid (or solar) charge you up.
