Hereinafter with reference to relevant indicators, describe preferred embodiment of the present utility model in detail.

Fig. 5 is a schematic diagram, shows the motor stator device according to the utility model preferred embodiment, wherein with aforementioned known techniques components identical with identical symbolic representation.With reference to Fig. 5, the motor stator device 300 of the utility model preferred embodiment comprises:

One annulus 301;

A most upper raised teeth 302, it is connected in annulus 301 outsides at interval, and is formed on one first plane;

A most lower raised teeth 303 are spaced according to annulus 301, with apparent place complementation on this majority upper raised teeth 302, and are formed on second plane of one and first plane parallel;
