High density motor winding with compacted litz wire bundle
A recently granted patent (Publication Number: US11942842B2) discloses a motor winding design that utilizes a high-density multi-conductor wire bundle, specifically a compacted Litz wire bundle. The winding features a unique serpentine configuration with a central portion comprising compacted Litz wire and end turns made of non-compacted Litz wire. The central portion undergoes a high-pressure press treatment to alter the cross-sectional shape of the individual jacketed conductors and reduce spacing between them, enhancing the efficiency of the winding.
Furthermore, the patent details a method for forming such a motor winding, involving compressing Litz wire to create a compacted Litz wire, shaping it into a serpentine winding with a central portion and end turns, and utilizing a press to compress only the central portion. Multiple bundles of compacted Litz wire can be combined through layering or weaving to form the winding, which can then be encased in a thermally conductive epoxy, potentially containing boron nitride. This innovative approach to motor winding design aims to improve performance and efficiency, offering a new solution for various applications requiring reliable and high-performance motors.
