Description

Technical Field

[0001] This utility model relates to the field of enameled wire varnish supply technology, and in particular to a nano-mixed insulating varnish supply device for a vertical enameling machine. Background Technology

[0002] With the development of technology, the application of variable frequency motors is becoming more and more widespread, especially in the field of new energy vehicles. Variable frequency motors generate high-frequency pulses during use. If ordinary enameled wire is used, insulation failure often occurs within 1-2 years. Therefore, in order to resolve the three major destructive factors of high-frequency pulses (electrical erosion, thermal aging, and chemical corrosion), corona-resistant enameled wire has emerged.

[0003] Corona-resistant insulating varnish is an essential insulating material in the production of corona-resistant enameled wire. Currently, the production of corona-resistant insulating varnish generally involves adding inorganic nanomaterials to the varnish. However, corona-resistant insulating varnish produced in this way often exhibits the phenomenon of inorganic nanomaterials agglomerating and settling during storage. This not only reduces the corona resistance effect but also significantly increases the scrap rate during enameled wire production, adversely affecting quality, cost, and product safety.
