Well, I had been giving it a lot of thought every since Loren suggested going with a rotary phase converter. So today I pulled the trigger. I bought an old compressor that has a 3 phase 10 hp motor. The motor works fine but the pump was broken. I was able to get the entire compressor with pressure switch, Baldor motor, magnetic switch, tank and pump for 200.00. So not a bad deal.
I hope this works great for us. The new to us Quincy compressor came with a huge motor that is 5 hp, 1740 RPM and 3 phase. Physically speaking, the 5 hp 3 phase motor is larger than either of our 7.5 hp single phase motors we have in our shop (one from the Speedaire, other from our Woodmaster planer). So I have decided we are going to run that 3 phase motor on the compressor since that is the original motor Quincy installed.
So this 10 hp phase converter should give us more options. Many auction or old used machines that are good deals are 3 phase. We currently have a nice Delta Unisaw with 52” bies fence and 5 hp 3 phase motor but no way of even using it :( I also have a 3 phase 1 hp power feeder that needs to be used. So we are looking forward to our adventure into 3 phase land.
Thanks for all of the advice from everyone.
I will try to update later next week after we get some 3 phase things going.
