Embodiment

Above-mentioned purpose of the present utility model with and 26S Proteasome Structure and Function on characteristic, will be illustrated according to the preferred embodiment of institute's accompanying drawing.

With reference to decomposition and the assembled sectional view of first embodiment of the present utility model among Fig. 1 and 2, as shown in the figure, described fan motor structure with waterproof and dust reduction capability comprises: pedestal 11, a housing 12 and a stator group 13;

Be vertically installed with a beam barrel 111 on the described pedestal 11, described beam barrel 111 has an axis hole 1111, and described axis hole 1111 is provided with at least one bearing 14.

Described housing 12 has a confined space 121, described housing 12 is set in the outside of described beam barrel 111, described housing 12 also has a cover portion 122 and a closure 123, described

cover portion

122 and 123 butt joints of described closure, be used for defining jointly described confined space 121, described cover portion 122 has a top side 1221, one first side 1222 and one second side 1223, be located at the two ends of described top side 1221 respectively, and extend to described pedestal 11, described top side 1221 is relative with described pedestal 11, described first side 1221 is relative with described second side 1223, and described top side 1221, pedestal 11, first side 1222 and second side 1223 define described confined space 121 jointly.

Described stator pack 13 is arranged in the described confined space 121, and described stator pack 13 also has plural silicon steel sheet 131, and described silicon steel sheet 131 outer a plurality of coils 132, circuit substrates 15 of side butt joint of described stator pack 13 of being wound with.

Decomposition and assembled sectional view with reference to second embodiment of the present utility model in Fig. 3 and 4, as shown in the figure, described fan with fan motor structure of waterproof and dust reduction capability comprises: pedestal 11, housing 12, stator group 13, a framework 16 and a rotor set 17;

The part assembly of present embodiment is identical with first embodiment with the corresponding relation between the assembly, so here no longer make an explanation, this fact Example only is that with the main difference of first embodiment present embodiment is the fan with fan motor structure of waterproof and dust reduction capability, so extending a plurality of elongated ends 1112, beam barrel 111 outer rims of described pedestal 11 connect described framework 16, constitute a fan frame 2, described rotor set 17 articulates with described bearing 14.
