Description

Technical Field

[0001] This utility model relates to the field of motor technology, and more specifically, to a cooling structure for an electric motor. Background Technology

[0002] Based on the form of electrical energy, motors can be divided into two main categories: AC motors and DC motors. AC motors can be further divided into single-phase AC motors and three-phase AC motors. According to different slip rates and operating principles, motors can also be divided into synchronous motors and asynchronous motors. Synchronous motors, based on their magnetic field, can be further divided into permanent magnet synchronous motors, hysteresis synchronous motors, and reluctance synchronous motors. Asynchronous motors include both induction motors and AC commutator motors. Induction motors can be further divided into three-phase asynchronous motors and shaded-pole asynchronous motors. Furthermore, based on protection types, motors can also be classified as enclosed, open, waterproof, submersible, watertight, and explosion-proof motors.

[0003] Motors generate heat during operation. Currently, the main way to dissipate heat is by opening heat dissipation holes on the motor housing. However, dust can easily enter the motor through these holes, affecting the lifespan of internal components.
