1. A motor winding comprising a high density multi-conductor wire bundle comprising a compacted Litz wire bundle comprising:
a) a serpentine configuration comprising a central portion and end turns; and
b) wherein the central portion comprises compacted Litz wire and wherein the end turns comprise non-compacted Litz wire, and wherein the compacted Litz wire comprises individual jacketed conductors, and wherein the central portion of the individual jacketed conductors being formed with high pressure press capable of providing 15 tons to 25 tons so as to change the cross-sectional shape of the individual jacketed conductors and reduce the spacing between individual jacketed conductors within the compacted Litz wire.
