Description

Stator structure

Technical field

The present invention relates to and a kind ofly can significantly promote motor running efficiency and reduce the stator structure of production cost.

Background technology

The social fan with cooling function has become very important part group in modern electronic product now, little of portable electronic device, greatly there are many electronic equipments to the vehicles, and often along with generation high temperature during the running of these electronic equipments, and then affect its task performance, even cause those electronic equipments to work as machine to stop, therefore, those electronic equipments mostly need to use fan to provide and dispel the heat and the temperature cooled to reduce electronic equipment, with the running making this electronic equipment energy stable.The reliability of fan own and durability are also guarantee that those electronic equipments can stablize the key factor of running, and the manufacturer producing fan now is there's no one who doesn't or isn't devoted to develop the fan type of more diversification to meet various different radiating requirements.

General conventional fan is on the market that the principle changed by stator group and a rotor polarization makes fan running, if for increasing fan running efficiency, it is made fado and adopts and increase extra silicon steel sheet storehouse again and increase sense magnetic surface and amass into promote moyor, but easily causes the increase on cost because increasing the storehouse of further silicon steel disc by this practice; In addition, referring to Fig. 1, is the three-dimensional combination figure of existing stator structure, and this practice adopts silicon steel sheet 10 to amass in the mode of the periphery formation protuberance 1011 of pole 101 to increase sense magnetic surface, reach the efficiency promoting motor, but this practice easily increases the problem of eddy current loss.

Refer to Fig. 2 again, for the stereogram of another existing stator structure, the silicon steel sheet of magnetic pole bodies is set as the silicon steel sheet band 20 of a preseting length by it, this silicon steel sheet band 20 has space 201, lug 202, each lug 202 also sets width according to winding correspondence, therefore space 201 will be had, the silicon steel sheet band 20 of lug 202 gives vortex winding in the form of a ring, and be all affixed, and each lug 202 formation must have setting quantity, the magnetic pole bodies at interval, existing general silicon steel sheet stacked manner one by one can be improved, but each lug 202 of this structure is necessary complete corresponding laminating in manufacture process, fit if not corresponding between lug 202 with lug 202, motor running efficiency can be reduced on the contrary.

The above, existing have following shortcoming:

1. need the more silicon steel sheets of storehouse to increase sense magnetic surface to amass, cause cost to increase;

2. increase eddy current loss;

3. reduce motor running efficiency.

Therefore, how to solve the above-mentioned problem commonly used and disappearance, the inventor being this case and the relevant manufactures being engaged in the industry desire most ardently the place, direction studied and improve.

Summary of the invention

The present invention is directed to the problems referred to above, the invention provides a kind of stator structure promoting motor running efficiency.

Secondary objective of the present invention, is to provide a kind of stator structure that significantly can reduce production cost.

Secondary objective of the present invention, is to provide a kind of stator structure reducing eddy current loss.

For reaching above-mentioned purpose, system of the present invention provides a kind of stator structure, comprise: a body, there is multiple pole, these poles to be stretched out institute's configuration by this body, and extend vertical with this body of these pole distal end faces has an extension, described extension has multiple projection, jointly defines a groove between described projection and projection.

Preferably, this body is made up of at least one first silicon steel sheet and the mutual storehouse of at least one second silicon steel sheet, and described extension is arranged at the end face of each pole end of this first silicon steel sheet.

Preferably, this second silicon steel sheet has more one first end face and one second end face.

Preferably, this first silicon steel sheet can be selected to be attached at described first end face or the second end face.

Preferably, this first silicon steel sheet is attached at described first end face and the second end face simultaneously.

Preferably, this projection and this groove are equidistant arrangement.

Preferably, this projection and this groove are Unequal distance arrangement.

Preferably, this body has more a perforation, and this perforation axially runs through described first silicon steel sheet and the second silicon steel sheet.

By the design of this structure of the present invention, when fan running, the projection formed on described extension, and then increase sense magnetic surface and amass, reaches and promotes motor running efficiency, and interconnected by projection and groove, can eddy current loss be reduced; In addition, the extra storehouse silicon steel sheet of existing need can be reduced and just can promote the cost that motor running efficiency produces.
