[0029] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0030] like Figures 1 to 3 As shown, an embodiment of this utility model provides a split-type external rotor motor structure, including:

[0031] Stator housing 1;

[0032] Stator shaft 10 is fixedly mounted on the central shaft on the inner surface of the stator housing 1;

[0033] Stator 2 is fixedly installed at one end of stator shaft 10 and is also fixedly installed on the outer surface of stator housing 1;

[0034] The stator housing 1 serves as the carrier for the stator shaft 10, stator 2, and rotor 6, while the controller housing 3 is detachably mounted from the stator housing 1.

[0035] The controller housing 3 is fixedly mounted on the outer surface of the stator 2.

[0036] The controller housing 3 houses the controller board 4, which can be separated from the stator housing 1. When developing new products or changing the product design for mass production, the structure of the stator 2 does not need to be changed; only the controller housing 3 needs to be changed.

[0037] like Figures 1 to 3 As shown, heat-conducting plates 8 are installed on the surfaces of the stator 2 and the controller housing 3. One side of the heat-conducting plate 8 is fixedly connected to the stator 2, and the other side of the heat-conducting plate 8 is fixedly connected to the controller housing 3.

[0038] When the controller board 4 is working, it generates a lot of heat. This heat is transferred from the controller housing 3 to the heat-conducting plate 8, then to the stator 2, and finally from the stator 2 to the stator housing 1 for further dissipation.

[0039] like Figure 1 and Figure 2 As shown, a controller plate 4 is fixedly installed on the inner surface of the controller housing 3, and a controller cover 5 is fixedly installed on the outer surface of the controller housing 3.

[0040] The controller housing 3 and the controller housing cover 5 serve to protect the controller board 4.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, a rotor 6 is rotatably mounted on the outer surface of the stator 2, and fins 7 are fixedly mounted on the rotating end of the rotor 6. The fins 7 are distributed in a ring at the rotating end of the rotor 6.

[0042] The rotor 6 drives the fins 7 to rotate, which can quickly dissipate the heat from the stator 2, stator housing 1 and heat dissipation fins 9 into the environment, thereby ensuring the normal operation of the equipment.

[0043] like Figure 3 As shown, heat dissipation fins 9 are welded and installed on the outer surface of the stator housing 1. The heat dissipation fins 9 are distributed in a ring on the outer surface of the stator housing 1 and are made of aluminum.

[0044] The heat dissipation fins 9 can increase the heat dissipation effect of the stator housing 1.

[0045] like Figure 3 As shown, the heat-conducting sheet 8 is made of aluminum.

[0046] In this embodiment of the utility model, the controller housing 3 and the stator housing 1 are designed separately. When developing new products or changing product plans for mass production, the structure of the stator 2 does not need to be changed. Only the controller housing 3 needs to be changed. Moreover, the controller housing 3 has a simple structure and small size, which can reduce the cost of mold investment compared to an integrated design.

[0047] Second, the same stator 2 can be standardized into one style, which makes the mold universal. For controller boards 4 with different power or different schemes, only the controller housing 3 needs to be matched.

[0048] 3. The controller housing 3 contacts the stator 2 through the heat-conducting plate 8. The heat generated by the controller board 4 can be transferred to the heat-conducting plate 8 through the controller housing 3, then to the stator 2, and finally to the stator housing 1 by the stator 2.

[0049] Fourth, the heat of the stator housing 1 can be dissipated by the heat dissipation fins 9, while the fins 7 of the rotor 6 can drive the airflow to quickly dissipate the heat of the stator housing 1 and the heat dissipation fins 9 into the environment.

[0050] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
