Claims20
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 individual jacketed conductors being formed with high pressure so as to change the cross-sectional shape of the individual jacketed conductors within the compacted Litz wire.
A method for forming a motor winding comprising:
- compressing a Litz wire to form a compacted Litz wire;
- forming a serpentine winding comprising the compacted Litz wire, the serpentine winding having a central portion and end turns;
- and
- wherein compressing the Litz wire comprises compressing only the central portion of the serpentine winding.
