  • Publication number: 20230290539
    Abstract: A method for forming magnet wire includes co-extruding multiple layers of different insulating materials. A conductor may be provided, and extruded insulation may be formed around the conductor by co-extruding both a first layer of thermoplastic insulation and a second layer of thermoplastic insulation with the second layer formed around the first layer. The first layer may include a first polymeric material having a first thermal index, and the second layer may include a second polymeric material having a second thermal index higher than the first thermal index.

  • Patent number: 11728067
    Abstract: Magnet wire with flexible corona resistant enamel insulation may include a conductor and a multi-layer insulation system formed around the conductor. The insulation system may include a basecoat formed from first polymeric enamel insulation, a midcoat formed from second polymeric enamel insulation, and a topcoat formed from third polymeric enamel insulation. The midcoat may include a filler containing silica dioxide and chromium oxide dispersed in a base polyamideimide material. Additionally, the magnet wire may exhibit few or no cracks in the topcoat when the wire is bent 180 degrees around a 4 mm mandrel.

  • Patent number: 11728068
    Abstract: Magnet wire with corona resistant enamel insulation may include a conductor and a multi-layer insulation system formed around the conductor. The insulation system may include a basecoat formed from a first polymeric enamel insulation. A midcoat formed from a second polymeric enamel insulation may be formed around the basecoat, and the second polymeric enamel insulation may include a filler dispersed in a base polyimide material. The filler may include between 20 percent and 80 percent by weight of silica dioxide and between 20 and 80 percent by weight of titanium dioxide. Additionally, the insulation system may include a topcoat formed from third polymeric enamel insulation formed around the midcoat.

  • Patent number: 11708491
    Abstract: Insulating films suitable for use in magnet wire, electrical machines, and other applications may include at least one layer formed from extruded material. The extruded material may include a blend of a first polymeric material and a second polymeric material different than the first polymeric material. The first polymeric material may include one of polyetheretherketone, polyaryletherketone, polyetherketoneketone, polyphenylsulfone, polyphenylene sulfide, or polybenzimidazole, and the second polymeric material may include one of polyphenylsulfone, polyetherimide, polyethersulfone, polyphenylene sulfide, polycarbonate, or polyester.

  • Publication number: 20230083970
    Abstract: Magnet wire including extruded insulation formed from a blend of different polymeric materials is described. A magnet wire may include a conductor and insulation formed around the conductor. The insulation may include at least one layer of extruded insulation formed from a blend of at least three different polymeric materials. A first polymeric material, such as polyetheretherketone, may have a thermal index above 250° C. Second and third polymeric materials, such as polyphenylsulfone and polyethersulfone, may have lower thermal indexes.
