Brick unforetally you can not convert the three phase motor to single phase with out useing the phase conveter at all

how big this motor is ?? if small to med size motor there are single phase avable up to 7.5 or 10 HP size but anything bigger useally 3 phase only.

and also you cant not run the 3 phase motor on single phase supply becasue it will burn up windings what we called single phasing it will not useally start at all but if it was running it will make koncking noise and it will draw more current also up to 2 X or more of running current

Merci , Marc
