A 3-phase induction motor in our factory had unequal phase currents. One of the currents was nearly normal while the other two were about twice the usual value. Somebody said that prolonged running causes increase in resistance of stator winding, and this results in increased current. But this explanation appears wrong at the very outset, because increased resistance should actually decrease the current.
What might the reason be?
