Embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer, the utility model is done further to describe in detail below in conjunction with accompanying drawing and embodiment.

See also shown in Figure 2, the cross section structure sketch map of a kind of brushless fan motor that Fig. 2 provides for the utility model embodiment.Brushless fan motor comprises rotor 21, stator 22 and the pedestal 23 that has flabellum among Fig. 2, and rotor 21 all is fixedly connected with said pedestal 23 with stator 22.

See also Fig. 3 and shown in Figure 4, Fig. 3 is the perspective view of stator 22, and Fig. 4 is the sectional view of said stator 22.Stator 22 is provided with at least one button hook 221, is four among the figure, and is preferred, and button hook 221 materials are a kind of in plastic cement, metal or the composite material.Correspondence is provided with at least one button bit hole 231 on the pedestal 23, is four among the figure, and stator 22 is connected with being fastened of button bit hole 231 through button hook 221 with pedestal 23.

Further, the brushless fan motor among Fig. 2 also comprises extensible member 24 and bearing 25, and is preferred, and extensible member 24 is a kind of in metal cylindrical spring, rubber cylindrical spring or the composite material cylindrical spring.

Extensible member 24 1 ends are pushed down stator 22, and the other end is pushed down bearing 25, and said bearing 25 is close to pedestal 23.Brushless fan motor also comprises the holding firmware 26 that is used for fixing rotor 1, and preferred, holding firmware 6 materials are that a kind of holding firmware 26 in plastic cement, metal or the composite material is fixed on the said pedestal 23.Rotor 21 is an assembly, and it comprises a core 211, and axle core 211 passes stator 22, extensible member 24 and bearing 25 backs and is fixedly connected with holding firmware 26.Extensible member 24 has the regulating action that adapts to stator 22 altitude conversions, and when stator uprises according to demand or during step-down, its extensible member 24 stretches down or stretches in the variation effect of stator 22 height, regulates oneself height automatically, to reach the purpose of rigid bearing 25.Promptly under the situation of stator 22 height change, need not change pedestal 23 or extensible member 24 members such as grade, extensible member 24 is regulated oneself height automatically with rigid bearing 25.

Fig. 5 is the cross section structure sketch map after the height of stator 22 on Fig. 2 basis increases.Fig. 6 is the cross section structure sketch map after the height of stator 22 on Fig. 2 basis reduces.Can find out that the brushless fan motor in the present embodiment can not need be changed member just can reach the fixing purpose of assembling.
