You need double the amps so if you have a 240v NA Main Single Phase Supply and run a 3 Phase 8.5A to10A Spindle Motor this will need the 240v supply to the VFD Drive to be 25A to 30A for 120v supply to do the same job then you would need a main power supply, which is not going to happen for 120v NA supply
I'm sure you know what you're talking about, but you haven't communicated that very well. I literally know LESS now than when I originally commented.
