Magnetic inuslated winding wire, also referred to as magnet wire, is used in a multitude of electrical devices that require the development of electrical and/or magnetic fields to perform electromechanical work. Examples of such devices include electric motors, generators, transformers, actuator coils, and so on. 

Typically, magnet wire is constructed by applying electrical insulation to a metallic conductor, such as a copper, aluminum, or alloy conductor. The conductor typically is drawn or formed to have a rectangular or round cross-section. The electrical insulation is typically formed as a coating that provides for electrical integrity and prevents shorts in the magnet wire. Conventional insulations include polymeric enamel films, polymeric tapes, paper insulation, and certain combinations thereof.

Traditional magnet wire is formed with polymeric enamel insulation that is applied in successive layers and baked in a furnace. In order to achieve higher dielectric and partial discharge performance, it is typically necessary to apply a greater number of layers and, therefore, thicken the enamel. 

The magnet wire may have a thermal classification of at least 220° C. in accordance with the American Society for Testing and Materials (“ASTM”) standard 2307. The magnet wire may also be resistant to various oils, liquids, and/or chemicals, such as transmission fluid. Additionally, the magnet wire may be capable of withstanding significant mechanical forces during a coil formation process.
