What would be the current of the 3-ph AC motor, if it lost one feeding phase?
The load, efficienty and power factor (theoreticly would say stay) constant.

But, of course, if it is some kind of example or test used in school, you can always calculate what current the three impedances pass. Wye or delta? Hint: does it really matter?

If the load is high, the motor may begin to stall with one phase missing.
