How Do I Make My Own Variable Frequency Drive?
I don't know much about this stuff. I don't have a rotary phase converter, or a static one for that matter, but I want to buy a more powerful motor for my lathe. Of course, it is a 3 phase motor, and I was hoping to be able to go from a step pulley system to a variable speed drive. Anybody know how to do this for the least amount of money? Thanks.

Here's what I am looking at
Well, I have my eye on an unused 4 HP, 3 ph, 1155 rpm motor. It's would cost about $275. However, I am not sure there is a VFD that can input single phase at this HP. I have only seen 3hp drives and lower with single phase input. Also, I haven't seen many 3 hp VFDs for less than $225. Do you guys have a specific source that's better than others? Thanks for all the info so far.
