Magnet wire with thermoplastic insulation

A magnet wire comprising:

• a conductor;
• and
• extruded insulation formed around the conductor, the extruded insulation comprising:
• a first layer formed around the conductor from a first polymeric material having a first thermal index, the first layer comprising at least fifty-five percent of a thickness of the extruded insulation;
• and
• a second layer formed around the first layer, the second layer formed from a second polymeric material having a second thermal index higher than the first thermal index.

A magnet wire comprising:

• a conductor;
• and
• extruded insulation formed around the conductor, the extruded insulation comprising:
• a first layer formed around the conductor from a first polymeric material having a first thermal index, the first polymeric material comprising at least one of polyester, nylon, polyphenylene sulfide, or polyphenylsulfone;
• and
• a second layer formed around the first layer, the second layer formed from a second polymeric material having a second thermal index higher than the first thermal index, the second polymeric material comprising at least one of polyetheretherketone, polyaryleetherketone, or polyetherketoneketone.
