I purchased a powermatic Model 90 lathe three phase thinking I could just put a different motor and switch to make work in my single phase shop. I found out that the variable speed also needs power. It has a baldor 1.5 hp 3 phase motor on it so what do I need for a converter rotary or static? I'm using the lathe mainly for turning for fun. I have a 1.5 single phase for it. Thanks in advance.
