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.

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.

Electric machines, such as motors, may include an armature and a field component, and at least one of the armature or the field component may include a laminated structure having a plurality of slots into which a plurality of conductive elements are positioned. Additionally, a polymeric insulation layer may be formed directly on the laminated structure at least within the plurality of slots.
