From time to time someone on this forum brings up 3 phase motors. Tools with 3 phase motors seem to be cheaper than single phase because I'm sure 3 phase is foreign to many of us. So I thought I would describe my experience to show how easy it is.
I purchased a used Rockwell table saw for my son that has a 3 phase 3hp motor.
I have experience with 3 phase motors as my own General table saw has a 3 phase motor. As a phase converter I bought a rotary phase converter. This setup requires that I initially have to start the motor on the phase converter before starting the tablesaw. Its an extra step that I don't have a problem doing but I wanted a simpler solution for my son as he is not as mechanically inclined as I am.
At any rate I bought a static phase converter on Ebay for $100 and wired in it. Once it is connected to the electrical panel it is simply a matter of plugging the saw in and using it. Just like you would with a single phase power source. A static converter reduces the power output of the motor by 1/3 so the 3 hp motor puts out 2 hp which is plenty of power.
It literally is that easy.
