Detailed description of the invention
Referring to Fig. 1 to Fig. 4, the embodiment with regard to the present invention illustrates.Fan motor 1 in this embodiment refer to for, such as, game machine, computer, computer peripheral equipment, auto-navigation system, the inside in the electronic equipment of various measurement devices etc. carries out heat release diffusion to outside.
Its two ends of axle 2 as gyroaxis fix axle holder 4a, 4b respectively.Axle holder 4a, 4b do not contact with shell 3.Each axle holder 4a, 4b fix the plectane 8a, the 8b that are made up of magnetic materials such as ferrum.Rounded round edge 9a, 9b then forms the outer circumferential side at disk 8a, 8b.Each blade 11a, 11b are separately fixed on each round edge 8a, 8b.As plectane 8a, the 8b of rotation dish fix Magnetitum 5a, 5b respectively.Different at the magnetic pole of axially opposing Magnetitum 5a, 5b.2, two axle holders 4 of axle, plectane 8a, 8b, blade 11a, 11b and Magnetitum 5a, 5b constitute rotatable rotor.Blade 11a (11b), round edge 9a (9b) and plectane 8a (8b) play the effect of yoke together.Especially, in this embodiment, blade 11a (11b) in plectane 8a (8b) outside, coil 10 and Magnetitum 5a (5b) are covered with, and, blade 11a (11b) is made up of magnetic, so, blade 11a (11b) is circumferentially in the outside of Magnetitum 5a (5b) and coil 10, and blade 11a (11b), round edge 9a (9b) and plectane 8a (8b) just cover magnetic flux together very fully.Just because of this, spilling of magnetic flux more it is prevented from.
Between gap between Magnetitum 5a, 5b, coil 10 is arranged on substrate 7.Substrate 7 has the circuit of the motor 1 driving fan.Substrate 7, leave axle 2 side farther out and be fixed on shell 3, leave the nearer side of axle 2 and be fixed on bearing 6.Bearing 6 is arranged between two axles holder 4a, 4b of axle 2.Bearing 6 is by the bearing being impregnated with oil, say, that made by oil-containing metal.Shell 3, substrate 7, coil 10 and bearing 6 (non-rotating structure) collectively form non-rotary stator.
As in figure 2 it is shown, the magnetic pole circumferentially adjacent to each other for Magnetitum 5a (5b) of circular plate type is geomagnetic into difference.Further, Magnetitum 5a and Magnetitum 5b along being axially opposite of axle 2 to magnetic pole mutually different.
As it is shown on figure 3, coil 10 is circumferentially equally spaced is provided with 4.Coil 10 is rolled in ellipticity, and its circumference is longer than axially.
The words of coil 10 are supplied electricity to by the terminal (not shown) that comes in and goes out, electromagnetic force will be produced, Magnetitum 5a (5b) just rotates, and axle holder 4a (4b), plectane 8a (8b) and blade 11a (11b) also rotate.Bearing 6 is fixed on substrate 7, does not rotate.It is to say, stator, off-axis 2 side farther out be fixed on shell 3, the nearer side of off-axis 2 is fixed on bearing 6.Stator is only integrally fixed at a place of bearing 6, so simple structure.Therefore cost can be reduced.Further, axle holder 4a (4b) does not contact with shell 3, and is housed in shell 3, so the overall thickness with the fan motor being constructed such that will not be big.
And, even if making bearing 6 and the mutual gentle contact of axle holder 4a, 4b, it is positioned at Magnetitum 5a between axle holder 4a, 4b and bearing 6, that be arranged on two plectanes 8a, 8b, yoke it is absent between 5b, so, unidirectional captivation will not be there is as prior art.Just because of this, less along the axial load of axle 2.So, consumption electric power is less.
Additionally, also can there be small space between bearing 6 and axle holder 4a, 4b.
The two ends of axle 2 are respectively provided with blade 11a, 11b, so, the hot-air of electronic equipment internal is just discharged to outside by high efficiency.
Further, it is consistent for being separately positioned on blade 11a, the 11b at axle 2 two ends phase place circumferentially, however, it is possible to its phase shifting circumferentially.Such as, as shown in Figure 4, blade 11a, 11b circumferentially stagger 60 °.Blade 11a, 11b circumferentially stagger the occasion of predetermined phase, if the antipodal words of the windup-degree of blade 11a and blade 11b, the antipodal wind in direction does not just produce from blade 11a side and blade 11b crosswind.Therefore, it is possible to the peripheral temperature at that reduce electronic equipment, to be positioned at axle 2 two ends is highly effective.
Further, although the number of blade of blade 11a and blade 11b is all 3 here, but it is not necessary to make the identical number of blade.
Further, in above-mentioned embodiment, although two sides at plectane 8a, 8b are respectively provided with Magnetitum 5a, 5b, but, Magnetitum also can only be provided in one of them of plectane 8a, 8b.Also have, it is possible to the 3rd Magnetitum is arranged on the face not having Magnetitum of plectane 8b, and coil is further disposed at relative with the 3rd Magnetitum.
Much less, the present invention is not limited to above-mentioned embodiment, can do all deformation without departing from the scope of the gist of the present invention.
