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.
