Embodiment
See also Fig. 2 to Fig. 4, Fig. 2 is the stereogram according to the utility model the first embodiment's Magnetic suspension fan 3, and Fig. 3 is the exploded view of the Magnetic suspension fan 3 among Fig. 2, and Fig. 4 is the part sectioned view of the Magnetic suspension fan 3 among Fig. 2.To shown in Figure 4, Magnetic suspension fan 3 comprises a base 30, a stator 32 and a rotor 34 such as Fig. 2.Base 30 is made by magnetic conductive material.In this embodiment, above-mentioned magnetic conductive material can be electrogalvanizing (SECC), but not as limit.Base 30 comprises an annular seat stand 300 and at least two protuberances 302, and wherein at least two protuberances 302 and annular seat stand 300 are one-body molded and be symmetric on annular seat stand 300.In this embodiment, three protuberances 302 are one-body molded with annular seat stand 300, and three protuberances 302 are symmetric on annular seat stand 300.In other words, the distribution angle of three protuberances 302 on annular seat stand 300 is 120 degree, as shown in Figure 3.It should be noted that the minimum number of protuberance 302 can be two, is not limited with three.For example, if the quantity of protuberance 302 is two, then the distribution angle of two protuberances 302 on annular seat stand 300 is 180 degree; If the quantity of protuberance 302 is four, then the distribution angle of four protuberances 302 on annular seat stand 300 is 90 degree; By that analogy.In practical application, can rely on punching press working process on annular seat stand 300, to go out protuberance 302.
As shown in Figure 4, after Magnetic suspension fan 3 assemblings were finished, a gap d was between magnetic part 344 and protuberance 302.In addition, projection and the protuberance 302 of magnetic part 344 on base 30 is at least part of overlapping.Thus, can be mutually after coil 322 energising excitatory and produce induced potentials with magnetic part 344, make magnetic part 344 produce angular displacements, and then drive rotating component 340 and rotate with rotating shaft 342, rotating component 340 can drive flabellum 346 and rotate and make Air Flow when rotating, with the effect of generation water conservancy diversion and heat radiation.Because base 30 is to make (that is protuberance 302 be magnetic conductive material) by magnetic conductive material, and the magnetic part 344 that is arranged on the madial wall of rotating component 340 is relative with protuberance 302, so understands the generation magnetic attraction between magnetic part 344 and the protuberance 302.When Magnetic suspension fan 3 running, the magnetic attraction that produces between magnetic part 344 and the protuberance 302 can make the rotating component 340 in the rotation keep stable and can not produce beat with rotating shaft 342, can guarantee that the magnetic field center line that magnetic part 344 has is aligned in the magnetic field center line that coil 322 produces, and then effectively reduce the vibration when turning round.The experiment proved that, when 0＜d≤0.7mm, can effectively reduce the vibration that Magnetic suspension fan 3 produces when running.In addition, because protuberance 302 and annular seat stand 300 are one-body molded, can effectively save the built-up time of Magnetic suspension fan 3.
Cooperate Fig. 4, see also Fig. 5, Fig. 5 is the part sectioned view according to the utility model the second embodiment's Magnetic suspension fan 3'.The main difference part of Magnetic suspension fan 3' and above-mentioned Magnetic suspension fan 3 is that projection and the protuberance 302 of the magnetic part 344 of Magnetic suspension fan 3' on base 30 is fully overlapping.When projection and the protuberance 302 of magnetic part 344 on base 30 complete when overlapping, can strengthen the magnetic attraction that produces between magnetic part 344 and the protuberance 302, so that the rotating component 340 in rotating and rotating shaft 342 keep stablizing and can not producing beat, and then effectively reduce the vibration when turning round.It should be noted that with the element of same numeral shown in Fig. 4, its action principle is roughly the same, does not repeat them here among Fig. 5.
In sum, the utility model lies in one-body molded at least two protuberances on the annular seat stand of base, and at least two protuberances are symmetric on annular seat stand.Because base made by magnetic conductive material, and the magnetic part that is arranged on the madial wall of rotating component is relative with protuberance, so can the generation magnetic attraction between magnetic part and the protuberance.When Magnetic suspension fan of the present utility model turned round, the magnetic attraction that produces between magnetic part and the protuberance can make rotating component and the rotating shaft in the rotation keep stable and can not produce beat, and then effectively reduces the vibration when turning round.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
