New description: [New technical field] [0001] The present invention relates to a heat dissipation structure of a motor device, and more particularly to a heat dissipation structure for a motor device. [Prior Art] [0002] Existing motors include a rotor and a stator. The rotor is a rotatable component. The stator is a stationary component. When the motor is running, high heat is generated in a local area inside the motor due to the stator rotor assembly. Therefore, in order to enable the heat generated during operation to be removed, heat-dissipating fins are usually added outside the motor to conduct heat generated by the stator-rotor assembly to the surface of the heat-dissipating fin, and an additional heat dissipation is added to enhance the heat dissipation effect. The fan uses the airflow generated by the cooling fan to forcibly remove the heat from the surface of the fins to the atmosphere. [0003] As shown in FIG. 7, a schematic perspective view of a conventional motor, the motor 90 is provided with a heat dissipation fin 91 on the outside thereof, and a heat dissipation fan 92 is disposed at the end of the motor 90, and is generated by the heat dissipation fan 92. The airflow dissipates heat from the external heat dissipating fins 91. Generally, a dust cover 93 is disposed on the outer surface of the heat dissipating fan 92, and a cover hole 931 is disposed on the dustproof cover 93 to facilitate airflow of the cooling fan 92 and to dissipate heat by using convection. The heat of the surface of the fin 92 is high. [0004] In the above-mentioned conventional technology, since the heat dissipation fan 92 is permanently placed at the end of the motor 90, the airflow generated by the heat dissipation fan 92 often cannot completely flow through the surface of all the heat dissipation fins 91, and the airflow is outside the space outside the motor 90. Generally, it can only flow through the surface of the front end heat dissipation fin 91 close to the heat dissipation fan 92, and the form number A0101 is 3, which is not more than the surface of the rear end heat dissipation fin 91 which is far from the heat dissipation fan 92, resulting in heat dissipation. The piece 91 has a heat efficiency of the surface of the rear end piece passing through the surface to be removed, and the airflow generated by all the surfaces of the (8) and the fan is not effective, so that the heat dissipation efficiency in the conventional technology still has room for improvement.
