1. The problem statement, all variables and given/known data Can we use a 3 phase delta supply to a 3 phase synchronous motor who's stator windings are connected in star (wye)? 3. The attempt at a solution I was thinking no, since I read in my notes that the rotor has to be supplied with a "continuous current" But I'm not sure. I have to justify my answer. I am also thinking maybe the phase differences won't match up and it won't work? I don't know. Can someone help clarify?
