Thanks for that John
I had seen 230V to 380V three phase VFD's advertised, just as well i came in for brew i was about to swop the motor covers and rotors again and commence on a box to send the single phase motor for a very expensive rewind.
was on a forum yesterday and some guy in the US added a stepup transformer before the inverter then bought a 440V to 440V VFD apparently that worked and i have seen another US made inverter that does the conversion from 220V to 440v.
Will contact Inverter Drive Supermarket
Regards
Mike
