The substrate is combined with a circuit plate which is used for bonding a ring chip-shaped coil with a silicon steel sheet with the binder, the rotor is provided with flaky magnet by the blade, the magnet and the coil are inducted in the spherical way to start.

Description

The composite set of small-sized heat radiating fan motor
The utility model relates to a kind of composite set of small-sized heat radiating fan motor, utilize the naked copper enameled cable to be wound into circular coil, this circular coil is adhered to silicon steel sheet and is adhered to circuit board surface again, make the alternating magnetic field that this circular coil produced and the permanent magnet interaction effect of rotor, form the mutual exclusion torque, to drive rotor rotation.
Prior art such as the two or two First Five-Year Plan of Taiwan patent announcement nine No. zero " stator structure of radiation fan " patent cases, it is winding around on the leg of magnetic pole yoke sheet, make coil after control circuit passes to impulsive current, stator coil can produce rotating magnetic field, drives rotor and rotatablely moves.Announce the 223 pseudo-ginseng No. four " the stator combined structure of small heat-dissipating fan " and announce number " the stator combined structure of small heat-dissipating fan " patent case the 2364 July 1st, it is winding around on the plastic cement seat, and on the plastic cement seat of coil two sides, be combined with upper and lower pole piece respectively, thereby form the stator structure of motor of heat-dissipating fan.Announce " structure improvement of direct current heat-dissipating fan " patent case the 23506 No. four, it is provided with coil base between upper and lower long-pending yoke sheet, form the magnetic pole induction by rotating magnetic field that coil produced via long-pending yoke sheet, and then the permanent magnet that drives rotor forms mutual repulsion effect and produces and rotatablely move.
The above-mentioned structure that prior art disclosed all has coil to cooperate magnetic pole yoke sheet to constitute the structure of stator, and then and utilizes coil base fixing for coil and pole piece combination.
Yet above-mentioned prior art structure owing to be subjected to the rotor driven restriction, also can't significantly be reduced the total thickness of radiation fan.
In view of this, the purpose of this utility model is to provide a kind of composite set of small-sized heat radiating fan motor, makes this radiation fan can have more the structure kenel of microminiature, ultrathin typeization.
For achieving the above object, the composite set of the small-sized heat radiating fan motor that provides of the utility model comprises:
One framework, its axle with flabellum of central siphon and rotor component wears and combines;
One stator member is incorporated on the framework with circuit board, and circuit board has control member, makes it can import power supply, makes coil electricity;
One rotor component, the axle set with flabellum passes the central siphon of framework, and the element limits that is positioned is in position rotating, itself is combined with magnet flabellum, can be with stator component coil-induced;
Wherein, this stator component has into the coil and the silicon steel sheet of ring plate shape, and it is combined on the circuit board by stalemate agent, its with the magnet of rotor between become the induction of face.
This framework has substrate, and the column jecket of setting is arranged on the substrate, column jecket internal diameter and central siphon assembly, and external diameter and circuit board are nested with.
The substrate of this framework is provided with several columns, but power circuit board is with the hole combination of planting.
Now with a preferred embodiment, conjunction with figs. describes structure characteristic of the present utility model in detail.
Fig. 1 is a three-dimensional exploded view of the present utility model.
Fig. 2 is a combination top view of the present utility model.
Fig. 3 is a 3-3 line sectional drawing among Fig. 2.
Fig. 4 is incorporated into schematic representation on the radiating fin for the utility model.
See also shown in Figure 1ly, the utility model comprises that framework 1, stator component 2, rotor component 3 etc. are main partly.
This framework 1 can be for the usefulness of stator component combination, it can become different shape or housing, and for making it have less thickness and radiating effect, it can be as shown in drawings, it is comparatively suitable to make frame by plastic cement material, framework 1 itself has substrate 11, this substrate 11 is formed with column jecket 12 in middle position, column jecket 12 itself can be nested with for a central siphon 13, and for making central siphon 13 be easy to assembly and preferable locating effect being arranged, column jecket 12 can be offered opening slot 14, column jecket 12 is had open and close elasticity, and can be provided with to projecting inward flange on the top that forms flap column jecket 12, central siphon 13 can be fixedly positioning, and support rotor rotation with central siphon 13 internal diameters; Be provided with several columns 15 on the substrate 11 in addition, but power circuit board 21 is with hole plant combination.
This stator component 2 comprises members such as circuit board 21, silicon steel sheet 22, coil 23, and circuit board 21 itself is combined with control members such as IC, and it can be introduced into power supply, so that the rotor action to be provided; Silicon steel sheet 22 and coil 23 flakiness shapes, its available stalemate agent is sticking to be put on circuit board 21, or is fixed on hole 221 on the column 15 of framework 1, when circuit board 21 is imported into power supply, can produce magnetic field by coil 23.
This rotor component 3 comprises flabellum 31, magnet 32, and magnet 32 is fixed on card in the flabellum 31, and establishes axle 33 by flabellum 31, can pass through central siphon 13 by axle 33, and fastens for align members 35 such as C shape rings with annular groove 34, but flabellum 31 relative stator members 2 are rotated.
See also combined situation of the present utility model shown in Fig. 2,3, because the utility model is only applicable to small-sized fans, coil 23 becomes the induction of face shape to design with magnet 32 by thin slice, and when coil 23 was led with power supply, the flabellum 31 of rotor 3 got final product rotary driving; Because coil 23 of the present utility model, silicon steel sheet 22 flakiness, and become the induction design of face with 32 of magnet, so, the structure that need repeat to be nested with between its two total thickness and diameter and known coil and magnet more all can significantly reduce, and when it is bonded to radiating fin (as shown in Figure 4), its total thickness also can significantly reduce, and with regard to the ultrathin design of small-sized heat radiating fan motor, has great breakthrough.
Structure of the present utility model has novelty, and with regard to product, its thickness can be greatly Reduce, to very big breakthrough is arranged on the product design demand, have progressive in fact, and this structure can Utilize on the industry.
