You'd need a transformer; either a 240-415 3-phase step-up transformer (and I don't know how well a transformer might like the output of a VFD) or a 240-415 single-phase transformer and a VFD for 415V single-phase, which I doubt exists.
If I wuz you I think I'd buy 240V motors. Most likely cheaper.
Or check to see if the existing motors can be rewired for 240V.
