SUMMARY
A 3-phase delta supply cannot be used effectively with a 3-phase synchronous motor whose stator windings are connected in star (wye). The rotor of a synchronous motor requires a continuous current, which is not provided by a delta connection when the stator is configured in star. Additionally, the voltage levels differ between the two configurations, as the delta voltage is lower than that of the star connection. Understanding the phasor diagrams for both configurations is crucial for justifying this conclusion.
