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.

A motor, also known as a motor, is a device that converts electrical energy into mechanical energy through electromagnetic action. Electric motors convert or transmit electrical energy based on the law of electromagnetic induction. According to the working principle, motors can be divided into electric motors and generators.
