[0002] Electric motors, commonly known as motors, are a relatively common type of mechanical equipment, generally used as a power source for various machines and electrical appliances. There are many types of electric motors, including permanent magnet motors. Compared with ordinary motors whose stators are coils, permanent magnet motors have permanent magnets in their stators, and only the rotors are coils. Permanent magnet motors have lighter weights, lower power consumption, and are flexible and diverse in size and shape, so they have a very wide range of applications.

[0003] In addition to being used in daily life, permanent magnet motors are also used in defense, aerospace and other fields. The wide range of uses also requires permanent magnet motors to meet the usage requirements in different environments. For example, some need to be used in humid environments.
