I have a grizzly static phase converter rated for 3-7.5 hp. I will be running a 3hp jointer and 5hp bandsaw with it. After doing more research, it appears that these static units are rough on motors and decrease power by 1/3.
I have not had issues with the decrease in power so at this point the power loss doesn't bother me.
Being in a small one-man shop, I don't see it being worth while to get a rotary converter as everything else I own is 220 single phase. I could replace the motors in these two units for less than the cost of the rotary converter.
I don't think either are vector motors, but if I use a vfd and don't manipulate frequency, will this create full, clean power?
My question: what would you do in my position? I could sell the converter/ 3hp leeson motor / 5hp motor while they still work great and use the money for single phase motors. I could also just run them till I have an issue, if ever. Maybe someone here has an even better idea? Not trying to overthink this, but just trying to be proactive.
thanks.
