[0002] A motor is a device that converts electrical energy into mechanical energy. It is mainly composed of a stator, rotor, housing, end caps, etc. During use, the motor generates a large amount of heat. When the heat reaches a certain level, the motor cannot be used. Otherwise, the insulation will break down and the motor will burn out.

[0003] Prior art publication number CN214506723U discloses a motor end cover with high-efficiency heat dissipation, including a motor and a rotating shaft, the rotating shaft passes through the front end cover and extends outside the front end cover, a first heat dissipation component is arranged in the front end cover, the heat dissipation component includes a partition plate, a first cooling fan, and multiple second cooling fans, the partition plate is arranged in the middle of the front end cover along the height direction of the front end cover, and a first installation space and a second installation space are formed when the front end cover is separated, a through hole connecting the first installation space and the second installation space is formed in the middle of the partition plate, the first cooling fan is placed in the first installation space, and the first cooling fan is fixedly mounted on the rotating shaft.

[0004] In the above device, multiple cooling fans are used to dissipate heat from the inside of the motor. Although the fans can accelerate the air flow inside the motor, the motor lacks a heat-conducting structure. The heat dissipation effect is poor only by accelerating the air flow, and it is difficult to effectively discharge the heat inside the motor. At the same time, the air sucked into the motor by the fan in the above device is air at room temperature. When the room temperature is high, the temperature of the inhaled air is high, which will affect the heat dissipation of the motor. Utility Model Content
