In some embodiments, mounting structure is provided between at least one of the magnetic rotor 102 and the mounting shaft 103 and the wind wheel 101, on which the magnetic rotor 102 and/or the mounting shaft 103 is provided. For example, a mounting structure is provided between the magnetic rotor 102 and the wind wheel 101, on which the magnetic rotor 102 is provided; or, a mounting structure is arranged between the mounting shaft 103 and the wind wheel 101, and the mounting shaft 103 is arranged on the mounting structure; alternatively, the wind wheel 101 is provided with two mounting structures, the magnetic rotor 102 is provided on one mounting structure, and the mounting shaft 103 is provided on the other mounting structure.

In some embodiments, as shown in FIG. 3, the divider 1021 is located within the space formed by the outer profile of the blade 1012. It can be understood that, in this way, the part of the separate part 1021 is prevented from being exposed out of the blade 1012, so that the separate part 1021 is prevented from occupying space, thereby saving space and reducing the overall volume of the wind turbine 101.

In some embodiments, the number of the separated parts 1021 and the number of the blades 1012 are equal and correspond to one another, that is, each blade 1012 is provided with the separated part 1021.

In some embodiments, the number of the divided parts 1021 is smaller than that of the blades 1012, wherein a part of the blades 1012 and a plurality of the divided parts 1021 correspond to each other, that is, any two adjacent divided parts 1021 may be arranged with a certain number of blades 1012 in between.

In some embodiments, the split 1021 has an exposed end that communicates with the outside, and the exposed end has a surface that is flush with the outer contoured surface of the blade 1012. That is, the exposed end of the separate part 1021 may be configured to be consistent with the outer contour surface of the blade 1012 by a profiling method, so that the separate part 1021 does not occupy the space inside the wind wheel 101, and the influence on the heat dissipation of the windings in the stator assembly 20 can be avoided.

In some embodiments, the split 1021 is integrally formed with the blade 1012. By this means, the split part 1021 and the blade 1012 can be made more integral, the structure is reliable, the separation does not occur, the step of mounting between the split part 1021 and the blade 1012 is omitted, and the mounting process is simplified. For example, the blade 1012 may be formed by an injection molding process, in which the separate part 1021 is directly molded on the blade 1012.

In some embodiments, any adjacent two of the plurality of blades 1012 define a blade gap therebetween, and a split portion 1021 is disposed in each blade gap. That is, the divided parts 1021 can be fitted not only into the blades 1012 but also into the blade gap formed between two adjacent blades 1012, so that a greater number of the divided parts 1021 can be fitted, thereby providing a uniform magnetic field.

The wind channel can play the effect of heat dissipation and ventilation, can form the negative pressure in wind channel department when wind wheel 101 is rotatory, drives the wind through the wind channel to can dispel the heat to stator module 20's winding. Referring to the foregoing, since the surface of the exposed end of the split part 1021 is flush with the outer contour surface of the blade 1012, the influence of the ventilation and heat dissipation of the air duct can be avoided.
