본 발명은 왕복동식 모터의 고정자 적층구조에 관한 것으로, 특히 내측고정자를 원통모양으로 적층하는 왕복동식 모터의 고정자 적층구조에 관한 것이다.The present invention relates to a stator stacking structure of a reciprocating motor, and more particularly, to a stator stacking structure of a reciprocating motor for stacking an inner stator in a cylindrical shape.

일반적으로 왕복동식 모터는 고정자조립체를 원통모양의 외측고정자와 내측 고정자로 분리하여 일정 공극을 두고 겹치도록 배치하고, 외측고정자와 내측 고정자 사이에 가동자조립체를 움직일 수 있도록 배치하며, 외측고정자와 내측 고정자 중에서 어느 한 쪽의 고정자에 권선코일을 장착하고, 이에 대응하는 가동자조립체에는 마그네트들을 부착시켜 가동자가 권선코일의 플럭스(flux)에 의해 축방향으로 왕복운동을 하도록 구성하고 있다.In general, a reciprocating motor separates a stator assembly into a cylindrical outer stator and an inner stator, so that the stator assembly overlaps with a predetermined gap, and moves the movable assembly between the outer stator and the inner stator, and the outer stator and the inner stator. The winding coil is mounted on one of the stators, and the magnet assembly is attached to the corresponding movable assembly so that the mover reciprocates in the axial direction by the flux of the winding coil.

도 1는 종래 왕복동식 모터의 일례를 보인 단면도이고, 도 2 및 도 3은 종래 왕복동식 모터의 내측고정자를 보인 사시도 및 정면도이다.1 is a cross-sectional view showing an example of a conventional reciprocating motor, Figures 2 and 3 are a perspective view and a front view showing the inner stator of the conventional reciprocating motor.

이에 도시한 바와 같이 종래의 왕복동식 모터는, 원통모양으로 형성하는 외측고정자(10)와, 상기 외측고정자(10)의 안쪽에 소정의 간격을 두고 배치하여 플럭스를 형성하도록 원통모양으로 형성하는 내측고정자(20)와, 상기 외측고정자(10)와 내측고정자(20) 사이에 배치하여 길이방향으로 왕복운동을 하는 가동자(30)로 이루어져 있다.As shown in the drawing, a conventional reciprocating motor includes an outer stator 10 formed in a cylindrical shape and a cylindrical inner shape formed to form a flux at a predetermined interval inside the outer stator 10. The stator 20 and the movable stator 30 are disposed between the outer stator 10 and the inner stator 20 to reciprocate in the longitudinal direction.

상기 외측고정자(10)는 복수의 얇은 스테이터코어(미부호)를 측면투영시 원호형상이고 정면투영시 "기역자"모양으로 적층하여 권선코일(13)의 외주면에 원주방향을 따라 적층하는 제1 코어블록(11)과, 상기 제1 코어블록(11)과 대칭되도록 '역기역자"모양으로 상기 권선코일(13)에 적층하는 제2 코어블록(12)로 이루어져 있다.The outer stator 10 is a first core for laminating a plurality of thin stator cores (unsigned) in the shape of an arc during side projection and in the form of "translator" during front projection along the circumferential direction on the outer circumferential surface of the winding coil 13. Block 11 and the second core block 12 is laminated on the winding coil 13 in the form of a 'back-tracker' so as to be symmetrical with the first core block (11).

상기 내측고정자(20)는 얇은 스테이터코어(21)를 소정의 형상으로 제작한 후 낱장씩 원주방향을 따라 방사상으로 적층하여 원통 모양으로 코어적층체(22)를 형 성하고, 상기 코어적층체(22)의 길이방향 양측에는 원통모양을 유지하도록 각각 고정링(23)을 압입하여 고정하고 있다.The inner stator 20 manufactures the thin stator core 21 in a predetermined shape, and then forms the core laminated body 22 in a cylindrical shape by laminating radially along the circumferential direction of each sheet, and the core laminated body ( The fixing rings 23 are press-fitted and fixed to both sides in the longitudinal direction of 22 to maintain the cylindrical shape.

도면중 미설명 부호인 24는 고정홈, 31은 마그네트프레임, 32는 마그네트, 41 및 42는 지지플레이트, 43는 체결볼트이다.In the figure, 24 is a fixing groove, 31 is a magnet frame, 32 is a magnet, 41 and 42 are support plates, and 43 are fastening bolts.

상기와 같은 종래 왕복동식 모터는 다음과 같이 동작한다.The conventional reciprocating motor as described above operates as follows.

즉, 상기 외측고정자(10)의 권선코일(13)에 전류를 인가하면, 상기 권선코일(13) 주변에 플럭스가 형성되어 외측고정자(10)의 일측 경로(path)를 따라 내측고정자(20)로 흘렀다가 다시 외측고정자(10)의 타측 경로로 흐르는 일종의 '폐루프(closed loop)'를 형성한다.That is, when a current is applied to the winding coil 13 of the outer stator 10, a flux is formed around the winding coil 13 to form the inner stator 20 along one path of the outer stator 10. After flowing to form a closed loop (closed loop) that flows to the other path of the outer stator 10 again.

이때, 상기 권선코일(13)에 의해 형성되는 플럭스 상에 상기 가동자(30)의 마그네트(32)가 놓이면 그 마그네트(32)가 상기한 권선코일(13)의 플럭스와 상호 작용하여 권선코일(13)의 플럭스 방향에 따라 밀리거나 당겨지면서 상기 마그네트프레임(31)이 직선으로 왕복운동을 하는 것이었다.At this time, when the magnet 32 of the mover 30 is placed on the flux formed by the winding coil 13, the magnet 32 interacts with the flux of the winding coil 13 so that the winding coil ( 13, the magnet frame 31 reciprocated in a straight line while being pushed or pulled along the flux direction.

그러나, 상기와 같은 종래 왕복동식 모터의 내측고정자에 있어서는, 도 3에서와 같이 두께가 같은 낱장의 스테이터코어(21)를 방사상으로 적층함에 따라 적층작업 자체가 난해할 뿐만 아니라 코어적층체(22)의 외주면으로 갈수록 폭이 넓어지는 틈새(t)가 발생하고 이로 인해 내측고정자(20)의 점적율이 낮아져 모터 효율이 저하되는 문제점이 있었다.However, in the inner stator of the conventional reciprocating motor as described above, as the stator cores 21 of the same thickness are laminated radially as shown in FIG. 3, the laminating operation itself is difficult and the core laminated body 22 is formed. A gap (t) is widened toward the outer circumferential surface of the problem occurs because the drop rate of the inner stator (20) is lowered, the motor efficiency is lowered.

또, 크기와 형상을 상이하게 형성하여 상호 교번되게 적층하는 복수의 스테이터코어부와, 상기 복수의 스테이터코어부 사이를 일체로 연결하여 그 스테이터코어부의 사이를 접어 적층할 수 있도록 절곡 가능하게 형성하는 코어연결부로 이루어진 왕복동식 모터의 고정자 적층구조를 제공한다.In addition, the plurality of stator cores are formed in different sizes and shapes to be alternately stacked with each other, and the plurality of stator cores are integrally connected to each other so as to be bent so as to be folded and stacked between the stator cores.

상기 내측고정자(100)는 후술할 스테이터코어부(111)(112)를 서로 연결되도록 타발 형성하여 그 스테이터코어부(111)(112)의 양단을 접어 원통모양으로 형성하는 코어적층체(110)와, 상기 코어적층체(110)의 양측면에 압입하여 원통모양을 유지하도록 하는 복수의 고정링(120)으로 이루어진다.The inner stator 100 is formed by punching the stator core parts 111 and 112 to be described later to be connected to each other, thereby folding both ends of the stator core parts 111 and 112 to form a cylindrical shape 110. And, it is composed of a plurality of fixing rings 120 to press the both sides of the core laminated body 110 to maintain a cylindrical shape.

상기 코어적층체(110)는 서로 동일한 크기와 형상으로 형성하거나 또는 도 4에서와 같이 상호 크기와 형상이 교번되게 상이하도록 형성하는 복수의 스테이터코어부(111)(112)와, 상기 스테이터코어부(111)(112) 사이에 일체로 연결 형성하여 상기 스테이터코어부(111)(112) 사이를 접어 적층할 수 있도록 절곡 가능하게 형성하는 코어연결부(113)로 이루어진다.The core laminated body 110 is formed in the same size and shape of each other, or as shown in Figure 4 a plurality of stator cores 111, 112 and formed so that the mutually different size and shape alternately, and the stator core portion The core connection part 113 is integrally formed between the 111 and 112 so as to be bendable to be folded and stacked between the stator core parts 111 and 112.

상기 스테이터코어부(111)(12)는 대략 직사각형 모양으로 형성하여 적층시 외주면을 이루는 꼭지점 부근을 연결하여 상기한 코어연결부(113)를 형성하되, 상기 스테이터코어부(111)(112)의 장축방향 양측면에는 상기한 고정링(120)을 압입할 수 있도록 고정홈(114)을 음각지게 형성하여 이루어진다.The stator cores 111 and 12 are formed in a substantially rectangular shape to connect the vicinity of the vertices that form the outer circumferential surface when stacked to form the core connecting portion 113, but the long axis of the stator cores 111 and 112 is formed. Both sides of the direction is formed by forming the fixing groove 114 intaglio so as to press-fit the fixing ring 120.

또, 상기 스테이터코어부(111)(112)는 그 크기와 형상이 상이한 경우에는 코어적층체(110)를 원통모양으로 형성함에 따라 외경측에서 코어간 간격이 발생하므로 그 코어간 간격을 작은 스테이터코어부(112)로 채워 틈새(t1)를 줄일 수 있도록 도 6에서와 같이 외경측은 동일한 반면 내경측은 크고 작은 형상으로 타발 형성하는 것이 바람직하다.In addition, when the size and shape of the stator cores 111 and 112 are different from each other, the core stack 110 is formed in a cylindrical shape, so that an interval between the cores is generated at the outer diameter side. In order to reduce the gap t1 by filling the core part 112, the outer diameter side is the same as in FIG. 6, but the inner diameter side is preferably formed in large and small shapes.

도면중 종래와 동일한 부분에 대하여는 동일한 부호를 부여하였다.In the drawings, the same reference numerals are given to the same parts as in the prior art.

상기와 같은 본 발명 왕복동식 모터에서 내측고정자를 제작하는 과정은 다음과 같다.The process of manufacturing the inner stator in the present invention reciprocating motor as described above is as follows.

먼저, 도 6에서와 같이 소정의 강판에서 복수의 스테이터코어부(111)(112)가 코어연결부(113)에 의해 일체로 형성될 수 있도록 타발 제작한다. 이때, 상기 스테이터코어부(111)(112)는 도면으로 제시하지는 않았으나 동일한 크기와 형상으로 형성할 수도 있고, 도면에서와 같이 서로 교번되게 크기와 형상을 상이하게 형성할 수 있다. 또, 상기 코어연결부(113)는 스테이터코어부(111)(112)의 적층시 외경측을 일치시킬 수 있도록 가급적 외주면과 동일선상에 얇게 형성하는 것이 바람직하다.First, as shown in FIG. 6, a plurality of stator core parts 111 and 112 are punched out to be integrally formed by the core connection part 113 in a predetermined steel sheet. In this case, although not shown in the drawings, the stator core parts 111 and 112 may be formed in the same size and shape, or may be formed in different sizes and shapes alternately with each other as shown in the drawing. In addition, the core connecting portion 113 is preferably formed thin on the same line as the outer circumferential surface so as to match the outer diameter side when the stator core portions 111 and 112 are stacked.

다음, 상기 스테이터코어부(111)(112)가 순서대로 적층되도록 상기 코어연결부(113)를 지그재그 모양으로 접어 코어적층체(110)를 형성한다. 이때, 상기 스테이터코어부(110)의 양측면에 형성하는 고정홈(114)이 서로 동일 선상에 위치하도록 지그 등을 이용하여 적층할 수도 있다.Next, the core connecting part 113 is folded in a zigzag shape so that the stator core parts 111 and 112 are stacked in order to form the core laminated body 110. In this case, the fixing grooves 114 formed on both side surfaces of the stator core unit 110 may be stacked using a jig or the like so as to be positioned on the same line.

다음, 원형 지그의 외주면에 상기 코어적층체(110)를 감아 그 코어적층체(110)가 원통모양을 이루도록 한다. Next, the core laminated body 110 is wound around the outer circumferential surface of the circular jig so that the core laminated body 110 forms a cylindrical shape.

다음, 상기 코어적층체(110)의 양측면에 구비한 고정홈(114)에 환형의 고정링(120)을 압입하여 상기한 코어적층체가 원통모양을 유지하도록 하는 것이다.Next, the annular fixing ring 120 is press-fitted into the fixing grooves 114 provided on both sides of the core laminate 110 so that the core laminate maintains a cylindrical shape.

이렇게, 상기 스테이터코어부가 코어연결부에 의해 일체로 연결됨에 따라 상기 스테이터코어부를 적층할 때 상기한 코어연결부를 순서대로 접어 코어적층체를 형성함으로써 낱장의 스테이터코어를 일일이 적층하는 것에 비해 스테이터코어의 적층작업을 훨씬 간소하게 할 수 있어 생산성을 크게 높일 수 있다.In this way, when the stator core parts are integrally connected by the core connection part, when stacking the stator core parts, the core connection parts are folded in order to form a core laminated body, thereby stacking the stator cores individually. This makes the job much simpler and can greatly increase your productivity.

또, 상기 스테이터코어가 크고 작은 형상이 교번되게 적층됨에 따라 각 스테이터코어부 사이의 틈새를 최소한으로 줄여 내측고정자의 점적율을 높일 수 있고 이를 통해 모터의 효율을 향상시킬 수 있다.In addition, as the stator cores are alternately stacked with large and small shapes, the gap between each stator core portion may be minimized to increase the spot ratio of the inner stator, thereby improving the efficiency of the motor.

본 발명에 의한 왕복동식 모터의 고정자 적층구조는, 복수의 스테이터코어부 사이를 코어연결부로 일체화하고, 그 코어연결부를 접어 상기한 스테이터코어부를 적층함으로써, 상기 스테이터코어의 적층을 용이하게 할 수 있어 생산성을 크게 높일 수 있을 뿐만 아니라 상기 스테이터코어부의 크기와 형상을 번갈아 적층되도록 상이하게 형성하여 상기 스테이터코어부 사이의 틈새를 최소한으로 줄이고 이를 통해 내측고정자의 점적율을 크게 높여 모터의 효율을 향상시킬 수 있다. The stator stacking structure of the reciprocating motor according to the present invention can facilitate stacking of the stator cores by integrating a plurality of stator core portions with a core connecting portion, and folding the core connecting portion to stack the stator core portions. Not only can the productivity be greatly increased, but the size and shape of the stator core parts are alternately stacked to minimize the gap between the stator core parts, thereby reducing the gap between the stator core parts to minimize the gap between the stator core parts, thereby improving the efficiency of the motor. Can be.
