Electric motors are important electromagnetic devices that provide power to various devices through the conversion of electrical and mechanical energy, and are an indispensable part of modern society.

Electric motors play an important role in production and daily life, especially in electric motors. According to statistics, electric motors consume over 60% of the electricity consumption. However, due to the frequent exposure of electric motors to harsh environments such as high temperature, high pressure, toxic, harmful, corrosive, humid, and dusty conditions, they are prone to malfunctions, which in turn affect the normal operation and safety of production equipment.
