Abstract
Enameled wire, as one of the three main insulating materials of motors, directly affects the output performance and service life of motors. To explore the performance of high-voltage flat wires with different coatings, this paper starts with the analysis of the insulation aging mechanism and establishes a multi-factor aging model of the main insulation copper wire-heat, humidity, oil and electricity. After multi-factor aging treatments such as high humidity, automatic transmission fluid, and high and low temperatures, the aging characteristics of flat wires with different coatings are verified.
