Embodiment
Hereinafter with reference to correlative type, a kind of fan, motor and magnetic conduction shell thereof according to preferred embodiment of the present invention are described, wherein components identical will be illustrated with identical reference marks.
Please refer to shown in Figure 2ly, comprise an impeller 20 and a motor 30 according to a kind of fan 2 of preferred embodiment of the present invention.The fan 2 of present embodiment is to be that example is illustrated with a tube-axial fan, also can be a centrifugal fan certainly.Impeller 20 comprises a wheel hub 201 and a plurality of flabellum 202, and this each flabellum 202 is located on the periphery of wheel hub 201.
The motor 30 of present embodiment is to be example explanation with an external-rotor motor, and it comprises a stator structure 31, a rotor structure 32 and a magnetic conduction shell 33.Wherein, magnetic conduction shell 33 comprises a body 34 and at least one first location structure 35, and body 34 has an end face 341 and a sidewall 342, and sidewall 342 is connected in the periphery of end face 341 and forms one opens the periphery setting of 343, the first location structures 35 along opening 343.The magnetic conduction shell 33 of present embodiment is an iron-clad.
As shown in Figure 3, the magnetic conduction shell 33 of its present embodiment and the stereogram of magnetic element 322.A plurality of first location structures 35 can be arranged at body 34 along sidewall 342 edge integral shapes of body 34, that is adjacent openings 343 and extend internally and form structure as the L shape, but the present invention is not restricted to this, first location structure 35 also can be two parts disconnected from each other with body 34, and row interconnects and forms again.In the present embodiment, first location structure 35 can be a trip, it has turning, that is be placed in the inner surface of sidewall 342 of magnetic conduction shell 33 when other when magnetic element 322, execute an external force again and make the location structure 35 of winning, make the right angle that forms about 90 degree between the sidewall 342 of win location structure 35 and body 34 towards the opening inner bending.Thus, can be limited in the magnetic conduction shell 33 magnetic element 322 and the location of finishing magnetic element 322 simultaneously.In addition, can be aided with adhesive agent and cohere, in order to add the usefulness of strong fix.Wherein, first location structure 35 has semicircle, half elliptic, triangle or polygonal profile.
Yet the execution mode of above-mentioned first location structure 35 is an illustrative only, is not to be limited to this, for example, as Fig. 4 and shown in Figure 5, first location structure 35 forms a predetermined angular A with the sidewall 342 of body 34, promptly by the interior part opening 343 that contracts with location magnetic element 322.Magnetic element 322 need be equipped with at least one corner cut B simultaneously, and corner cut B corresponds to the predetermined angular A of first location structure 35, the corner cut that is magnetic element 322 cooperates the angle setting of contracting in first location structure 35, so that the tight holding magnetic element 322 of first location structure 35.
