It'll be cheaper to buy a new motor. Single phase to 3 phase 440v VFDs are very expensive. Or use the Steinmetz connection as already suggested.
micktoon:
Hi Bob, you have had it running on normal three pin 240 volt mains plugged into wall socket I think ? , if so it must be single phase, does the plug just have live , neutral and earth wires going to the plug ?
Cheers Mick

Bob,
It can still be three phase even if it is 220 Volt.
Here is the three phase equipment configurations available according to my manual.
Voltage Frequency Ref Number for motor
440 60 ZMO 56 3440
220 60 ZMO 56 3220
500 50 ZMO 56 3500
350 50 ZMO 56 3350
440 50 ZMO 56 3440
380 50 ZMO 56 3380
220 50 ZMO 56 3220
In the single phase versions the last four number set will start with a 1, not a 3.
Hope this helps.
My three phase 440 volt EMCO is running quite happily off my single phase domestic supply (admittedly through a 220-440 step up transformer) with a Steinmetz capacitor to create the third phase.
If yours turns out to be a three phase 220 Volt motor it should run just as well with only the capacitor.
Dave.
DavidA:
I missed the bit where it says you had it running on single phase.
Sorry about that.
Dave.

hi as really lost off gnaw all the in fo that's on the motor I have posted the motor is weird up the same way as wires go on me lath motor and that's 240 volt so I weird the mill up in the same way and plugged it in and it runs no strange noises runs all the speeds dus not get hot the cap dus not get hot ? so its ether 240 volt or 440 volt that will run on 240 volt will probelys take it to the motor rewind place and get sum info of them as bin lookin at them inverter things on the bay and its all Japanese to me
