Zusammenfassung:Magnet wire with corona resistant enamel insulation may include a conductor, and at least one layer of polymeric enamel insulation may be formed around the conductor. The 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 oxide and between 20 and 80 percent by weight of titanium oxide. Additionally, the polymeric enamel insulation may have a thermal index of at least 260° C. and a thermal index that is at least twice that of the base polymeric material.
