Polyimide(PI) varnishes with different SiO2 content were designed,and then making paint films for performance research,corona-resistant PI varnishes with suitable SiO2 content were obtained.The corona-resistant PI enameled wire and the self-adhesive corona-resistant PI enameled wire were further prepared,and then the performance of the two types of enameled wire was studied.The results shown that the self-adhesive corona-resistant polyimide enameled wire can still maintain the excellent performance of the corona-resistant PI enamelled wire.At the same time,the introduction of Hein epoxy self-adhesive paint can greatly simplify the manufacturing process of the coil windings,which can save electricity and labor were conducive to realizing production automation and improving product quality.
