All the 3 phase motors I've seen here in the UK are 440/220 depending on whether they are wired in Star or Delta. You just remove a cover and shift 3 links to changeover. I've done it on 2 motors which I now run on a vfd which is single phase 220 volt. I also ran my lathe motor and a 3 hp milling machine motor on single phase for 20 years before vfd converters became cheap and commonplace. I set the links to delta and put single phase across 2 of the delta points and a capacitor bank to the 3 point giving me the phase shift. The only drawback is you lose starting torque but that does not matter in most cases. The method is well known and described in the book Electric Motors by Cox [used to be by MAP but not sure who prints it now].
