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.
