[0002] The rotor assembly is an important part of rotating equipment such as motors, and usually includes: rotor core, windings, shaft, blades and other structures. When the motor rotates at high speed, it will bring about certain energy conversion and heat generation, and the changes and interactions of the magnetic field may also cause certain energy to be converted into heat. In addition, when the current passes through the winding, due to the resistance of the winding, Joule heat will also be generated, resulting in heat, which can easily affect the stability of the rotor assembly.
