[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Different types of electric motors are widely used in different environments. During the operation of the motor, a heat dissipation device is required to dissipate the heat of the motor as a whole to improve work efficiency.

[0003] In the related art, in the patent with application number CN202321640973.2, a three-phase asynchronous motor is provided.
