Problems solved by technology

[0005] However, the structure of the outer rotor motor 1 has insufficient sealing performance due to the large number of gaps between the various components, making its protection effect poor.
For example, there is a gap G between the rotor 11 and the bearing housing 10, so foreign matter, water vapor or external dust in the external environment can easily enter the interior of the outer rotor motor 1 through the gap G, causing abnormality or damage to the motor, thus reducing the performance of the outer rotor motor 1.

Abstract

The invention provides a fan with dustproof and thermal discharge functions and a motor thereof. The motor comprises a shell that is provided with a closed space and composed of a heat conduction material, a stator fixed in the shell, and a rotor, which is provided with a rotating shaft and arranged through the stator and one end of which projects out of the closed space to be connected with an impeller, wherein, the stator and the rotor are contained in the closed space.

Description

technical field [0001] The invention relates to a motor, in particular to a motor and a fan with dustproof and heat dissipation functions. Background technique [0002] Motors are components used to convert electrical energy into mechanical energy, and have been widely used in mechanical structures in daily life, such as fans. There are many types of motors, which can be roughly divided into inner rotor motors and outer rotor motors, and the main difference between the two is that the position of the rotor is set on the inside or outside of the motor. [0003] Please refer to figure 1 As shown, the existing external rotor motor 1 includes a bearing housing 10 , a rotor 11 , a stator 12 and a circuit board 13 . The bearing housing 10 includes a shaft tube portion 101 , and at least one bearing 102 is accommodated in the shaft tube portion 101 . The rotor 11 includes a rotating shaft 111 , an iron shell 112 and a magnetic ring 113 . The rotating shaft 111 is embedded in the...
