Jon, are you sure about the motor frame size? 145T is common. Dave

I agree Rod. Delta to wye step up isolation is usually my first choice. Autotransformers are usually lighter and cheaper but not so much as the voltage change gets wide but at least the step up vs step down becomes irrelevant. I built a three phase transformer using two single phase transformers but sure don't want to open that can of worms. In this case it probably doesn't work economically unless the neighbor has a working one in the garbage pile. Dave
