Magnet wire with flexible corona resistant enamel insulation may include a conductor and a multi-layer insulation system fomied around the conductor. The insulation system may include a basecoat fomied from first polymeric enamel insulation, a midcoat formed from second polymeric enamel insulation, and a topcoat fomied 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.

Alambre magneto con aislamiento de esmalte resistente a efecto corona flexible puede incluir un conductor y un sistema de aislamiento multicapa formado alrededor del conductor. El sistema de aislamiento puede incluir una capa base formada a partir del primer aislamiento de esmalte polimérico, una capa intermedia formada a partir del segundo aislamiento de esmalte polimérico y una capa superior formada a partir del tercer aislamiento de esmalte polimérico. La capa intermedia puede incluir un agente de relleno que contiene dióxido de sílice y óxido de cromo dispersado en un material de poliamidaimida base. De manera adicional, el alambre magneto puede presentar pocas o ninguna grieta en la capa superior cuando el alambre se dobla 180 grados alrededor de un mandril de 4 mm.

Un alambre magnético con aislamiento de esmalte resistente al efecto corona puede incluir un conductor y un sistema de aislamiento multicapa formado alrededor del conductor. El sistema de aislamiento puede incluir una capa base formada de un primer aislamiento de esmalte polimérico. Una capa media formada de un segundo aislamiento de esmalte polimérico se puede formar alrededor de la capa base, y el segundo aislamiento de esmalte polimérico puede incluir un relleno dispersado en un material de poliimida base. El relleno puede incluir entre 20 por ciento y 80 por ciento en peso de dióxido de sílice y entre 20 y 80 por ciento en peso de dióxido de titanio. Adicionalmente, el sistema de aislamiento puede incluir una capa superior formada del tercer aislamiento de esmalte polimérico formado alrededor de la capa media.
