The Agni and the motors above has a special layout of the windings, but how the windings are layed out shouldn't have anything to do with saturation of iron. Using a solid conductor or 100 parallel insulated wires only affects fill factor.
The flux in the iron is going to be a function of the amps x number of turns. If the number of turns is 1, it takes a lot of amps to saturate. The Agni also does not have 'teeth' on the iron that are more prone to saturation.
