Abstract
Magnet wire with corona resistant enamel insulation is described. A magnet wire 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 polymeric material, such as polyimide. Additionally, the filler may include an organometallic compound.
Claims18
A magnet wire comprising:
- a conductor;
- and
- at least one layer of polymeric enamel insulation formed around the conductor, the polymeric enamel insulation comprising a filler dispersed in a base polymeric material,
- wherein the filler comprises an organometallic compound formed from a transition metal, the organic compound comprising one of carbamate salt, thiocarbamate salt, thiophosphate salt, or an amine salt of a metal oxide acid, and
- wherein the filler comprises less than 5.0 percent by weight of the polymeric enamel insulation.

A magnet wire comprising:
- a conductor;
- and
- filled polymeric enamel insulation formed around the conductor, the filled polymeric enamel insulation comprising a base polymeric material and a fully soluble organometallic compound formed from a transition metal,
- wherein the filled polymeric enamel insulation has a partial discharge inception voltage that is at least five percent greater than that of the base polymeric material.
