Description

편평형 진동모터의 전기자{A ARMATURE OF FLAT TYPE VIBRATION MOTOR}Armature of a flat vibration motor {A ARMATURE OF FLAT TYPE VIBRATION MOTOR}

본 발명은 편형형 진동모터의 전기자에 관한 것으로써, 특히 3돌극 편재형의 전기자에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the armature of a flat vibration motor, and more particularly to a three-pole poled armature.

휴대전화기나 단말기등에는 호출용 신호로서 진동모터가 사용되고 있다.BACKGROUND OF THE INVENTION A vibration motor is used as a call signal in a mobile phone or a terminal.

이러한 종류의 진동모터는 전기자의 돌극 및 권선의 편재배치에 의해 중심의 불평형으로 회전에 따라 진동력을 발생시키는 것이다(예를들면 일본국 특개평 9 - 182366호 공보 참조).Vibration motors of this kind generate vibrational forces as they rotate unbalanced at the center by uneven placement of the armature poles and windings (see, for example, Japanese Patent Laid-Open No. 9-182366).

종래의 전기자를 도시한 도1의 중앙돌극(1)에 대하여 좌ㆍ우측 돌극 (2,3)의 사이에는 열린 슬롯(4,4)을 형성하고 있어 중앙 코일(5) 및 좌ㆍ우측의 코일(6,7)은 플라이어에 의해 철심요크에 권선되지만, 불규칙적으로 권선되어 얇고 고밀도의 정렬권선은 불가능해진다. 또 열린 슬롯(4,4)에 의한 자계의 불균일은 코깅을 발생하여 큰 기전력을 필요로 한다.The center coil 5 and the left and right coils are formed with open slots 4 and 4 between the left and right salient poles 2 and 3 with respect to the center salient pole 1 of FIG. (6,7) is wound on the iron core yoke by a pliers, but is irregularly wound so that a thin, high density winding is impossible. In addition, non-uniformity of the magnetic field by the open slots 4 and 4 generates cogging and requires a large electromotive force.

그러나, 상기 공보에 기재된 편평형 진동모터는 전기자의 구성이 3돌극 열린 슬롯으로 하고, 이것에 의한 코깅은 기동전력 및 소비전력을 크게 하고 있다. 또 플라이어에 의한 권선은 고밀도의 정렬권선이 불가능하여 불규칙적으로 권회되므로, 코일은 두껍고 불균일하여 소형화 및 박형화에 지장을 초래하고 있다.However, in the flat vibration motor described in the above publication, the armature has a three-pole open slot, and cogging thereof increases the starting power and power consumption. In addition, since the winding by the pliers cannot be wound with high density, it is wound irregularly, and the coil is thick and nonuniform, which causes the miniaturization and thinning.

코깅을 방지하기 위하여, 열린 슬롯을 닫힌 슬롯으로 하는 방법이 있지만, 닫힌 슬롯에서는 권선이 불가능해지고, 개별적인 공심코일의 삽입수단이 필요해진다.In order to prevent cogging, there is a method in which the open slot is a closed slot, but winding is impossible in the closed slot, and a means for inserting individual air core coils is required.

따라서, 본 발명은 상기 목적을 달성하기 위하여 이루어진 것으로써, 본 발명의 목적은 기동전력 및 소비전력을 저감시킬 수 있는 편평형 진동모터의 전기자를 제공하는데 있다.Accordingly, the present invention has been made to achieve the above object, and an object of the present invention is to provide an armature of a flat vibration motor that can reduce the starting power and power consumption.

본 발명의 다른 목적은 편중량을 증대하여 강한 진동을 출력할 수 있는 편평형 진동 모터의 전기자를 제공하는데 있다.Another object of the present invention is to provide an armature of a flat vibration motor capable of increasing the weight to output a strong vibration.

본 발명의 또 다른 목적은 열린 슬롯에 따른 강 코깅을 약화시킬수 있는 편평형 진동모터의 전기자를 제공하는데 있다.Another object of the present invention is to provide an armature of a flat vibration motor that can weaken the steel cogging according to the open slot.

상기 목적을 달성하기 위하여 본 발명은 3개의 편재돌극의 주변에 돌출된 금속띠를 연결하여 닫힌 슬롯으로 하고, 또 중앙 돌극의 권선 요크의 중심부에서 좌우 돌극의 권선 요크를 분리가능하도록 슬릿을 형성하고, 중앙돌극의 양단을 지지점으로하여 연결용 금속띠에 의해 좌우로 열린 3개의 공심정렬 권선코일을 삽입하고 재결합이 가능하도록 구성한 것을 특징으로 한다.In order to achieve the above object, the present invention connects the metal strips protruding around the three uneven protrusion poles to form a closed slot, and forms a slit to separate the winding yoke of the left and right pole poles from the center of the winding yoke of the central pole pole. It is characterized in that it is configured to enable recombination by inserting three concentric alignment winding coils opened to the left and right by a metal band for connection with both ends of the central salient pole as a support point.

도 2 내지 도 5에 도시한 바와 같이 본 발명에 있어서 전기자는 돌극(1, 2, 3)의 주변의 가장자리에 돌출된 부분은 그 연장의 금속띠 (8, 8)에 의해 연결된 닫힌 슬롯으로 되어 있다. 이 때문에, 중앙권선요크(11)의 중심부(14)에서 좌우 권선요크(12,13)와의 결합위치에 슬릿(15, 16)을 형성하여 도 3에 도시한 바와 같이 중앙 돌극(1)의 양단(a, a)을 지지점으로 해서 금속띠(8, 8)를 개재하여 좌우에 열린 공심정렬 권선코일(5, 6, 7)을 요크(11, 12, 13)에 삽입, 도 4a에 도시한 바와 같이 닫고, 슬릿(15, 16)은 스폿 용접하거나 도 4b에 도시된 바와 같이 보강판(17)을 대어서 스폿 용접하여 완결한다.In the present invention, as shown in Figs. 2 to 5, the armature protrudes at the periphery of the periphery of the salient poles 1, 2 and 3, and is a closed slot connected by the metal bands 8 and 8 of the extension. have. For this reason, the slits 15 and 16 are formed in the engagement position with the left and right winding yokes 12 and 13 at the center 14 of the central winding yoke 11, and as shown in FIG. The hollow core alignment winding coils 5, 6 and 7, which are opened to the left and right through the metal bands 8 and 8, are inserted into the yokes 11, 12 and 13 with (a, a) as a supporting point, as shown in Fig. 4A. The slit 15, 16 is completed by spot welding or by spot welding against the reinforcing plate 17 as shown in FIG. 4B.

도 5a는 몰드의 예를 도시하는 평면도로써, 닫힌 슬롯(8, 8)인 것과 코일은 고밀도 정렬권선에 의해 정형평면화되어 있으므로, 중앙 코일(5)을 중심으로 하여 닫힌 슬롯에 의한 공간과 인접코일의 공간을 비중이 큰 자기적으로 코깅감소효과가 있는 철분이 혼합된 수지를 사용하여 일체화한 몰드(19)를 가능하게 하고, 오목부를 형성해서 편평형 정류자(18)를 장착한 것이다. 도 5b는 저면도이다.Fig. 5A is a plan view showing an example of a mold, in which the closed slots 8 and 8 and the coils are orthogonally flattened by high density alignment windings, so that the space and the adjacent coils by the closed slots are centered around the center coil 5; It is possible to mold (19) in which the space of the magnetic body is mixed using a magnetically mixed iron powder having a large specific gravity, and the concave portion is formed to mount the flat commutator 18. 5B is a bottom view.

본 발명에 의하면, 3개의 편재돌극의 주변에 돌출된 부분은 그 연장의 금속띠에 의해 연결하고 닫힌 슬롯으로 함으로써 코깅이 현저하게 약하게 되고, 기동전력과 소비전력의 저하를 초래한다. 또 3개의 공심정렬 권선코일의 삽입은 전기자의 박형화 및 모터의 박형화를 가능하게 함과 동시에 닫힌 슬롯의 공간과 인접코일의 공간을 포함하여, 비중이 큰 철분이 혼입된 수지에 의해 몰드로 편중량을 증가시켜, 진동력을 강화하는 한편 코깅을 더욱 약하게 하는 효과가 있다.According to the present invention, the portions protruding around the three uneven projection poles are connected to each other by the metal bands extending, and the closed slots significantly weaken cogging and cause a decrease in starting power and power consumption. The insertion of three concentric winding coils enables the thinning of the armature and the thinning of the motor, as well as the closed slot space and the adjacent coil space. It is effective to increase the vibration force while strengthening the cogging force.
