Radiator fan generally refers to also set for mainboard devices cooling fan, some of radiator fans such as CPU, video cards
There is cooling fin, main purpose is to achieve the effect that cooling in the air near transferring out to come heat and blowing in fact.It is existing
After loading onto flabellum, four pole centers (magnetic most strength) of magnetic stripe can stop traditional heat-dissipating fan automatically under the magnetic force
The place nearest from silicon steel sheet (with a distance from nearlyr magnetism stronger)；After coil is powered, magnetic field is formed on silicon steel sheet, in the same sex
Repel each other, under the principle that there is a natural attraction between the sexes, the magnetic force moving fan rotation of generation.Positive and negative rotation radiator fan on the market is usually now
Three-phase motor, i.e., such radiator fan are typically provided the Hall sensor of three equidistant triangle settings, and structure and coiling are multiple
Miscellaneous, material and cost of labor are higher, production technology is complicated is easy to bad products occur.Hall (Hall) sensor is according to suddenly
A kind of magnetic field sensor of your effect production, is known as Hall element or Hall subassembly using element made of this phenomenon, extensively
Ground is applied to industrial automation technology, detection technique and information processing etc..
Summary of the invention
To overcome above-mentioned deficiency, the purpose of this utility model is that a kind of radiator fan motor is provided to this field is single-phase positive and negative
Rotation mechanism, make its solve existing similar product using three-phase motor technology cause complicated electric machine winding, material and cost of labor compared with
High, production technology complexity is easy to the technical issues of bad products occur.The purpose is to what is be achieved through the following technical solutions.
A kind of single-phase positive and negative rotational mechanism of radiator fan motor, the single-phase positive and negative rotational mechanism of the motor are set to the fan of radiator fan
In leaf rotor, i.e., the iron-clad in flabellum rotor is equipped with more than two symmetrically arranged magnetic stripes, and magnetic stripe is sequentially connected composition ring shape,

Use and the further improvement of similar product.
Detailed description of the invention
Fig. 1 is one structural schematic diagram of the embodiments of the present invention.
Fig. 2 is two structural schematic diagram of the embodiments of the present invention.
Figure number and title: 1, iron-clad, 2, silicon steel sheet, 3, magnetic stripe, 4, main Hall element, 5, secondary Hall element.
Specific embodiment
Now in conjunction with attached drawing, the utility model structure and use are further described.Embodiment one as shown in Figure 1, the electricity
The single-phase positive and negative rotational mechanism of machine is set in the flabellum rotor of radiator fan, i.e., the iron-clad 1 in flabellum rotor is equipped with and symmetrically sets two-by-two
The magnetic stripe 3 set, positive and negative anodes are sequentially connected setting between magnetic stripe, and magnetic stripe is sequentially connected composition ring shape, and magnetic stripe corresponds to silicon steel sheet 2 and divides
Not She You electromagnetic coil, the positive and negative anodes of electromagnetic coil and the positive and negative anodes of magnetic stripe are corresponding, and the silicon steel sheet center in flabellum rotor is equipped with
Stator axis；The positive and negative anodes magnetic stripe of iron-clad side is respectively equipped with main Hall element 4 and secondary Hall element 5, main Hall element, secondary Hall
