Sung-Hong Wan在頒予三星電機公司(Samsung Electro-Mechanics Co., Ltd·)之第6, 169,348 號美國專 利「扁平式雙相振動馬達」("Flat Type Two-Phase ’Sung-Hong Wan awarded US Patent No. 6,169,348 "Flat Type Two-Phase" to Samsung Electro-Mechanics Co., Ltd.
Vibration Motor")之中揭示了一種扁平式的兩相振動馬 達’其使用了機械構造不對稱的轉子,使轉子的重心偏離 轉子轉軸,以在轉子轉動時產生振動。不過,Wan之振動 馬達必須使用換流器配以電刷(brush)來對其轉子上的線讀_ 圈繞組(c 〇 i 1 w i n d i n g )供電。 電刷與換流器由於是依賴機械性的磨擦接觸來產生作 用,因此無可避免地會有電刷及換流器導電段 (commutator segments)磨耗,以及因而造成的導電段之 ,電性短路的問題。同時,電刷與換流器導電段之間的間 續導電性接觸,無可避免地會產生電磁雜訊,易對電子線 路造成干擾,導致電路停機。並且,電刷及換流器的磨耗 則直接地限制了振動馬達的使用壽命。另一方面,其兩相 電源供應的需求,必須使用兩組具有相差的個別電源才2 滿足,相較於單相的電源,顯然整體成本及馬達動带= 複雜度皆較高。 勒私路 因此,本發明之一目的即在於提供一種直流無刷振 達,其可以利用内置偏心配重的方式產生振動,但 電路組件機械磨耗的困擾 …. 光除 五、發明說明(3) 本發明之再_ ΗVibration Motor ") discloses a flat two-phase vibrating motor 'that uses a rotor with asymmetrical mechanical structure, which makes the center of gravity of the rotor deviate from the rotor shaft to generate vibration when the rotor rotates. However, Wan's vibration motor must use an inverter with a brush to power its wire-reading coil windings (c 0 1 w i n d i n g). Since the brush and the inverter rely on mechanical frictional contact to produce the effect, it is inevitable that the brush and the commutator segments of the inverter will be worn away, and the resulting conductive segments will be electrically shorted. The problem. At the same time, the continuous conductive contact between the brush and the conductive section of the inverter will inevitably generate electromagnetic noise, which will easily cause interference to electronic circuits and cause circuit shutdown. In addition, the wear of brushes and inverters directly limits the life of the vibration motor. On the other hand, its two-phase power supply needs to be met by using two sets of individual power supplies with different phases. Compared to single-phase power supplies, it is clear that the overall cost and motor drive belt = complexity are higher. Therefore, one of the objectives of the present invention is to provide a DC brushless vibration generator, which can generate vibration by means of a built-in eccentric weight, but the mechanical wear of circuit components is plagued by light.

In addition: the square =, the positioning protrusion 119 on the winding core 113 can also extend an appropriate length toward the motor, so as to provide a suitable separation room between the stator " ο and the other two components along the motor axis . For example, when the printed circuit board 131 of the motor driving circuit 130 is installed in the motor housing 190, the upper and lower magnets lu and u 2 are each: Yes, it is made of conductive silicon steel material. The proper isolation distance between the second circuit of the drive circuit port 1 and the upper or lower magnet U1 or 112 = the need for miniaturization in many applications. This isolation distance must often be accurately controlled to a minimum. By precisely making the length of the positioning post 11 9, this distance can be accurately controlled. In the embodiments of FIGS. 1 and 2 above, the motor driving circuit 130 is on a printed circuit board, but the driving circuit can also be installed by other methods. The perspective view of Fig. 7 shows another safe way of the motor drive circuit. In Fig. 7, the drive circuit of the motor is placed on the upper surface of the stator. For example, since the upper magnet 111 may be made of magnetically permeable 111 steel, it will also conduct electricity. However, as long as the surface and surface on the upper magnet, such as shown in FIG. 7, form a substantially circular surface road 1, and a local insulation layer 135 is laid thereon, a driving circuit including a driving IC can be laid back thereon. 132, Hall sensors 134,,; two necessary circuit components.

、 'V 五、發明說明(13) 轉子1 2 0亦可以固定在一支隨著轉子轉動的旋轉心軸上, 而此旋轉心軸則可以其兩端裝置於固定在馬達外殼1 9 〇上 的軸承上。 圖1與2中所顯示之偏心轉子構造,僅係為本發明直流無 刷振動馬達之一種可能轉子構形。圖3至6中分別顯示了四 種其他可行的偏心轉子構造,同樣具有構造簡單,製造容 易的優點。例如,圖3之偏心轉子1 2 0 A包含有一環形磁鐵 129,一偏心配重塊124A,以及一轉子軸承150。其中,環 形磁鐵129與轉子軸承150係具有與圖1及2中之實施例相似 的構造,偏心配重塊1 24A則具有局部環形的構造。例如, 偏心配重塊1 24A可以擁有一個完整圓環大約三分之二長度 的環形週緣部份,其餘大約三分之一的環體則被切除,形 成空間1 2 7 A。如此,其可以具有足夠長度的週緣内表面, 在諸如黏劑等的固著作用之下,便可以很方便且穩固地將 轉子軸承1 5 0夾固在其定位上。由於偏心配重塊1 2 & a相對 於轉子120的旋轉中心具有不對稱的質·量分佈,因此在旋 轉時即會產生振動。 圖4的轉子120B,與圖3相較之下,則具有另一種形式的 不對稱構形。其偏心配重塊124B基本上具有環形體的構 形’但在其環形體長軸的中心位置,沿其一選定徑向方 向,於其外週緣表面以一個厚度切入,形成了一個缺口 127B。由於環形體的缺口127B部份的質量被移除掉,'故亦 造成了偏心的效果。 圖5的轉子120C又具有另一種形成偏心的構形。其偏心V. Explanation of the invention (13) The rotor 1 2 0 can also be fixed on a rotating mandrel that rotates with the rotor, and the rotating mandrel can be fixed to the motor housing 1 90 at both ends. Bearing. The eccentric rotor structure shown in Figs. 1 and 2 is only one possible rotor configuration of the DC brushless vibration motor of the present invention. Four other feasible eccentric rotor configurations are shown in Figures 3 to 6, which also have the advantages of simple construction and easy manufacturing. For example, the eccentric rotor 120A of FIG. 3 includes a ring magnet 129, an eccentric weight 124A, and a rotor bearing 150. Among them, the ring magnet 129 and the rotor bearing 150 have a structure similar to that of the embodiment shown in Figs. 1 and 2, and the eccentric weight 1 24A has a partially annular structure. For example, the eccentric weight 1 24A can have an annular peripheral portion of about two thirds of the length of a complete ring, and about one third of the ring body is cut away to form a space 1 2 7 A. In this way, it can have a peripheral inner surface with a sufficient length, and it can easily and stably clamp the rotor bearing 150 in its position under the fixed function such as an adhesive. Since the eccentric weight 1 2 & a has an asymmetrical mass / quantity distribution with respect to the rotation center of the rotor 120, vibration occurs during rotation. The rotor 120B of Fig. 4 has another form of asymmetrical configuration compared with Fig. 3. Its eccentric weight 124B basically has the configuration of an annular body ', but at the center position of the long axis of the annular body, it is cut into the outer peripheral surface with a thickness along a selected radial direction to form a notch 127B. Because the mass of the notch 127B of the ring body is removed, it also causes an eccentric effect. The rotor 120C of FIG. 5 has another configuration that forms an eccentricity. Eccentric

Description of the invention (14) = The ring body part of block 124C is substantially parallel to the long axis of the ring body, and there are four holes 127C formed in the example in FIG. 5. These holes are distributed asymmetrically relative to the center of rotation 'so that the center of the eccentric weight mc is offset from the center of rotation of the rotor. As can be understood by those skilled in the art, these holes 127C can be transparent or not, but they can cause the center of mass of the rotor 120C to deviate from the center of rotation of the rotor. The rotor 120D of Fig. 6 is yet another preferred embodiment of the present invention for forming an eccentric rotor configuration. In this embodiment, the eccentric weight 1241) is basically a ring-shaped structure, but one of the two female and two ends along the symmetrical center axis of the ring carcass is cut off obliquely. The part of the ring body, that is, the cut-out portion 127D indicated by the dashed line in the figure, forms a substantially elliptical cut surface. : The cut-out portion 127D destroys the symmetry of the cylindrical body, so that the center of mass of the eccentric weight 124D deviates from the center of rotation of the rotor. In this way, whether using any one of FIGS. 3 to 6 or other rotor configurations that seem to deviate from the centroid, when assembled, the DC brushless vibration motor of the present invention is attached to the outer peripheral surface of the ring magnet 129 of the rotor 120 An air gap 140 is formed between the magnetic pole pieces 115 and 116 of the upper and lower magnets 111 and 112 of the stator iiq. An external power supply line 1 3 3 extended electrically from the printed circuit board of the driving circuit 30 μ can supply the DC power provided by the external power supply to the driving circuit 130. Under the induction driving control of the Hall sensor 134 and the driving IC 132, this external power source can be appropriately supplied to the stator / winding 114 of the stator 110 to drive the rotor 120 to rotate. The rotor 1 20 is equipped with an eccentric weight 1 24, which causes the rotor 1 20 to rotate. 5. In the description of the invention (15), a person who can produce mechanical properties, the DC brushless of the present invention is thrown away by a mobile phone such as a mobile phone. The use of the larger example is called a wide range of uses. Although the foregoing descriptions describe it, various repairs are still possible. For example, the printed circuit board of the drive circuit is provided outside the motor housing which meets extreme miniaturization and the like. Due to the formation of a certain thickness, if the size can be reduced even more, it is based on a Hall sensor as the driving type of induction device, such as light. For example, although a typical motor, it is the vibration motor of the present invention. For another example, although the cylindrical body and its shell are mentioned above, the present invention can also be used for the upper and lower end plates of the magnet, and can also provide a suitable method for the rotor. Of course, this form is firmly fixed to each other, for example

This invention has been changed. Mounted to the motor, the driver printed circuit board mounted it. For another example, the circuit provides a stator and a rotor in a transfer inductor, and the corresponding housing end of each embodiment adopts a housing structure such as a rotary bearing in other forms. For example, the structure of the above embodiment and the structure The internal circuit of the above-mentioned preferred housing is the 1C motor body above it. Although the aforementioned position information of each sub-section is also the same as the number of magnetic poles, the number of magnetic poles is in the middle. It has a plate to form a vibration. This is also a complete equivalent embodiment of the magnet which may have to be on the axial direction of the magnet, but as if it can be installed outside the circuit element, it is in the motor embodiment, but the other shapes are the same as applicable. The outer upper and lower set structures of the internal air moving motor that are recessed can be different, which is also convenient and feasible. The inner peripheral edge of the wall of the lower set magnet is suitable.
