I'm in the process of buying a cnc for my house. I have run into a few problems. I was planning on getting a VFD to run it since it is 3 phase but realized they don't make them big enough for single phase input. The motor is a 10hp but it says 10/15 which I'm guessing means max draw for the 15hp. 230v 3 phase and a full max draw of 65amps but normal use about 36amps. I know I can go massively oversized on a 3 phase input vfd like 30hp to make up for the 50% derate but I would need to shut my house power off whenever I wanted to use it since I would need like a 125 amp breaker for it and I'm sure if you can run a vfd that large single phase. I looked into digital phase converters but that's gonna run me like 3200$ base and also needs about a 125 amp breaker the guy told me. My next idea was what I didn't want to use which is a rotary phase converter but am not sure what size I should get and also I believe will require probably a 100 amp breaker which is what my garage subpanel is. Anyway could definitely use some help on this maybe people who have run into the same problem and what you did or should I just scrap my plan of this machine and look for something with a smaller motor or just look for a minimill and eliminate this headache I'm causing for my self haha.
