Looks like I'm a few months late to this party, but here's some helpful information on table saws and phase converters: A table saw is one of the easiest machines to run on a static converter. The obvious advantages are they're cheap and easy. The tradeoff is, you'll lose 1/3 of your horsepower because you aren't really running your saw on 3-phase. All a static converter does is provide an artificial phase to get the motor running, using start capacitors. As soon as the motor starts, the static converter drops out of the circuit becoming a passive device, and all it does is allow the saw motor to continue running directly on single phase power. If you measure the voltage between the windings, it's all over the place because there are no run capacitors to balance it out. For long term use in an industrial setting, you're going to shorten the life of a fairly expensive motor.
I make static converters, but I'm not a big fan of them. I always tell my customers that they'll be much happier with a rotary converter that will give them true three phase power, and a well-balanced output. It really doesn't cost that much more. Our Phase-Craft model 10-HP-18 gives you true three phase power, and currently only costs $200, plus around $100-$150 for a used 10-HP 3-phase 1700-1800 RPM idler motor, which you can usually find pretty easily at a metal scrap yard or Craig's List.
A static converter only has start capacitors which start your 3-phase motor on single phase, and then drop out of the circuit. A rotary phase converter control panel will start your idler motor the same way, but when the start caps drop out of the circuit, it also has run capacitors that help to balance your output voltage. Output voltage balance is a moving target and is never perfect, but by matching our control panels to both the horsepower AND the RPM of your idler motor, we're able to get it pretty close… close enough to run CNC machinery if the panel is sized correctly for your machine.
Another advantage to a rotary phase converter, is they're virtually bulletproof. We've got converters out there that have been running in industrial settings for close to two decades with no problems. I've yet to hear of a VFD that can make that claim, plus a 10-HP rotary panel can usually run several different machines in a typical home workshop. We make control panels from 3-HP up to 25-HP, but the 10-HP panel definitely gives you the most bang for your buck. You can see most of our panels at a certain online auction site, but we also take direct orders over the phone, and I'm always happy to answer questions, whether you buy a converter from me or not.
