VFD - Do I understand this correctly???

Looks like the right frame. Double check it to be sure.

I installed an offshore vfd in my lathe a while ago seems to work ok, no issues as of yet

Nothing yet. This is what I'm contemplating. My mill has a 2 HP 1 PH 220 V motor. I'm thinking of upgrading the motor to 3 HP 3 PH 220 V and using a 220 V 1 PH to 220 V 3 PH VFD for speed control. By the sounds of things I should be looking at a 5 HP VFD for a 3 HP motor? Are all 3 PH motors VFD compatible? Am I missing some key detail? Just trying to figure out if this is feasible and what the cost would be.

i am running a baldord 3ph 3hp 240v on a 2.2kw vfd with remote control(wired) on my lathe and love it with no problems running it up to 120hz. i am thinking of putting in a braking resistor but its not necessary.
