Which motor that you're interested?

If you're referring to induction motor, may be it's possible if you could rearrange the stator windings, e.g. put two windings on its stator that are displaced 90° from each other. One winding is connected directly to the single-phase supply. For starting (i.e. to produce a rotating magnetic field), the other winding is connected through a capacitor to the same supply.

Suggestion:
Instead of struggling with conversion of this motor, why not to emply a divice that changes single phase into three phase supply.
Thes devices are called VSD (variable speed drive).
They are inexpensive and commonly available in wide variety of sizes to suit 3-phase motors.

That's a good suggestion, frankly speaking.

river78, do mind to share why do you wish to convert 3-phase machine to single phase? Is it because you do not have 3-phase supply? Or, is it for your own interest or assignment by your lecturer? Thanks.
