본 발명은 왕복동식 모터의 고정자 구조에 관한 것으로, 특히 모터의 직경을 늘리지 않고도 코일의 권선량을 증가시킬 수 있는 왕복동식 모터의 고정자 구조에 관한 것이다.The present invention relates to a stator structure of a reciprocating motor, and more particularly to a stator structure of a reciprocating motor that can increase the winding amount of the coil without increasing the diameter of the motor.

일반적으로 왕복동식 모터는 입체적인 구조를 갖는 모터의 자장(Magnet Field)을 평판 형상으로 변형시킨 것으로, 평판으로 형성된 가동자조립체를 역시 평판으로 형성된 고정자조립체의 상측에 얹어 자장 변화에 따라 직선으로 움직이도록 한 것이다.In general, a reciprocating motor is a deformation of a magnetic field of a three-dimensional motor (Magnet Field) into a flat plate shape, so that the mover assembly formed of a flat plate is also placed on the upper side of the stator assembly formed of a flat plate to move in a straight line according to the change of the magnetic field It is.

최근에는 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 왕복운동하도록 하는 왕복동식 모터가 소개되고 있다.Recently, the stator assembly is divided into a cylindrical outer stator and an inner stator, and arranged to overlap a predetermined gap, and the movable assembly is disposed between the outer stator and the inner stator, and one of the outer stator and the inner stator is disposed. A reciprocating motor has been introduced in which a winding coil is mounted on a side stator, and a magnet assembly is attached to a corresponding movable assembly so that the mover reciprocates axially by a flux of the winding coil.

도 1는 종래 왕복동식 모터를 측면에서 보인 단면도이고, 도 2는 외측고정자의 고정상태를 보인 단면도이다.1 is a cross-sectional view showing a conventional reciprocating motor from the side, Figure 2 is a cross-sectional view showing a fixed state of the outer stator.

이에 도시한 바와 같이, 종래의 왕복동식 모터는 플럭스를 형성하는 고정자조립체(10)와, 고정자조립체(10)의 플럭스에 따라 왕복운동을 하는 가동자조립체(20)로 구성하고 있다.As shown in the drawing, the conventional reciprocating motor includes a stator assembly 10 that forms a flux and a movable assembly 20 that reciprocates according to the flux of the stator assembly 10.

고정자조립체(10)는 원통형으로 형성하는 외측고정자(11)와, 역시 원통형으로 형성하여 외측고정자(11)의 안쪽에 소정의 코어간 거리(이하, 공극과 혼용함)를 두고 배치하는 내측고정자(12)로 이루어져 있다.The stator assembly 10 has an outer stator 11 formed in a cylindrical shape, and an inner stator formed in a cylindrical shape with a predetermined inter-core distance (hereinafter, mixed with a void) inside the outer stator 11. It consists of 12).

외측고정자(11)는 도 2에서와 같이 그 내부에 권선코일(C)을 삽입하는 보빈 체(11a)와, 다수 장의 얇은 스테이터코어를 원호형상으로 적층하여 상기한 보빈체(11a)의 양쪽 외측면에 끼워 결합하는 복수 개씩의 코어블록(11b)과, 각 코어블록(11b)의 양측 외측면을 지지하는 복수 개의 코어플레이트(11c)와, 양측 코어플레이트(11c)를 조여 상기한 코어블록(11b)을 지지하는 체결볼트(11d) 및 체결너트(11e)로 이루어져 있다.The outer stator 11 has a bobbin body 11a for inserting the winding coil C therein as shown in FIG. 2, and a plurality of thin stator cores are stacked in an arc shape to form both outer and outer sides of the bobbin body 11a. A plurality of core blocks 11b joined to the side surfaces, a plurality of core plates 11c supporting both outer surfaces of each core block 11b, and both core plates 11c are tightened to fix the core blocks ( It consists of a fastening bolt (11d) and a fastening nut (11e) for supporting 11b).

보빈체(11a)는 플라스틱과 같은 절연재를 속이 빈 환형 모양으로 형성하고, 코어블록(11b)은 보빈체(11a)의 양측에서 서로 끼워 고정하도록 "기억자"모양과 이에 대향하는 "역기억자"모양으로 형성하고 있다. 또, 체결볼트(11d)는 도 3에서와 같이 자성체인 철 재질로 형성하여 코어블록의 사이를 통과하도록 배치하고, 체결너트(11e)는 체결볼트(11d)에 체결하여 맞은편 코어플레이트(11c)의 바깥면에 밀착 결합하고 있다.The bobbin body 11a forms a hollow annular shape such as plastic, and the core block 11b has a "memory" shape and an opposite "reverse memory" to be fixed to each other on both sides of the bobbin body 11a. "Is shaped. In addition, the fastening bolt (11d) is formed of a magnetic material as shown in Figure 3 and disposed so as to pass through between the core block, the fastening nut (11e) is fastened to the fastening bolt (11d) opposite the core plate (11c) It is closely attached to the outer surface of).

가동자조립체(20)는 외측고정자(11)와 내측고정자(12) 사이에서 움직일 수 있도록 배치하는 가동자몸체(21)와, 고정자조립체(10)의 권선코일(C)에 대응하도록 가동자몸체(21)의 외주면에 원주방향을 따라 등간격으로 고정하는 마그네트(22)들로 이루어져 있다.The mover assembly 20 has a mover body 21 arranged to move between the outer stator 11 and the inner stator 12 and the mover body so as to correspond to the winding coil C of the stator assembly 10. The outer circumferential surface of the (21) is composed of magnets 22 fixed at equal intervals along the circumferential direction.

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

즉, 외측고정자(11)의 권선코일(C)에 전류를 인가하면, 권선코일(C)의 주변에 플럭스가 형성되어 외측고정자(11)의 일측 경로(path)를 따라 내측고정자(12)로 흘렀다가 다시 외측고정자(11)의 타측 경로로 흐르는 일종의 '폐루프(closed loop)'를 형성하고, 권선코일(C)에 의해 형성되는 플럭스 상에 가동자조립체(20)의 마그네트(22)가 놓여 그 마그네트(22)가 상기한 권선코일(C)의 플럭스와 상호 작용하면서 플럭스 방향에 따라 가동자몸체(21)가 직선으로 왕복운동을 하는 것이었다.That is, when a current is applied to the winding coil C of the outer stator 11, a flux is formed around the winding coil C to the inner stator 12 along one path of the outer stator 11. Flowing and forming again a kind of 'closed loop' flowing to the other path of the outer stator 11, the magnet 22 of the movable assembly 20 on the flux formed by the winding coil (C) As the magnet 22 interacts with the flux of the winding coil C, the movable body 21 reciprocates linearly along the flux direction.

그러나, 상기와 같은 종래 왕복동식 모터에 있어서는, 상기한 체결볼트(11d)가 자성체를 띔에 따라 철손을 고려하여 그 체결볼트(11d)와 권선코일(C)과의 절연거리(L)를 적정하게 유지할 수 있도록 코어플레이트(11c)의 직경을 넓히거나 권선코일(C)의 감김량을 상대적으로 줄여야 하는 문제점이 있었다.However, in the conventional reciprocating motor as described above, in consideration of iron loss as the fastening bolt 11d squeezes the magnetic material, the insulating distance L between the fastening bolt 11d and the winding coil C is appropriate. There was a problem in that the diameter of the core plate 11c or the winding coil C should be relatively reduced so as to maintain it.

본 발명은 상기와 같은 종래 왕복동식 모터가 가지는 문제점을 감안하여 안출한 것으로, 코어플레이트의 직경을 넓히지 않고도 권선코일의 감김량을 늘려 모터 효율을 높일 수 있는 왕복동식 압축기의 고정자 구조를 제공하려는데 본 발명의 목적이 있다.The present invention has been made in view of the problems of the conventional reciprocating motor as described above, to provide a stator structure of the reciprocating compressor that can increase the motor efficiency by increasing the amount of winding of the winding coil without increasing the diameter of the core plate There is an object of the present invention.

본 발명의 목적을 달성하기 위하여, 권선코일을 감은 환형의 보빈체와, 여러 장의 스테이터코어를 적층하여 상기 보빈체의 양측면에 방사상으로 끼워 배치하는 수 개의 코어블록과, 코어블록의 바깥쪽 양측면에 밀착하여 지지하는 복수 개의 코어플레이트와, 보빈체의 외주면에 근접하여 코어블록의 사이를 통과하도록 그 외주면에 절연층을 구비하여 상기 양쪽 코어플레이트를 조여 고정하는 수 개의 체결부재를 포함한 왕복동식 모터의 고정자 구조를 제공한다.In order to achieve the object of the present invention, an annular bobbin wound around a winding coil, several stator cores are laminated to several core blocks arranged radially on both sides of the bobbin body, and on both outer sides of the core block. A reciprocating motor including a plurality of core plates in close contact with each other, and several fastening members for tightening and fixing both core plates by having an insulating layer on the outer circumferential surface thereof so as to pass between the core blocks close to the outer circumferential surface of the bobbin body. Provide a stator structure.

이하, 본 발명의 왕복동식 모터의 고정자 구조를 첨부도면에 도시한 일실시예에 의거하여 상세하게 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, the stator structure of the reciprocating motor of this invention is demonstrated in detail based on one Example shown in an accompanying drawing.

도 4는 본 발명 왕복동식 모터에서 외측고정자의 고정상태를 보인 단면도이고, 도 5는 도 4의 "Ⅰ-Ⅰ"선단면도이며, 도 6은 본 발명 왕복동식 모터에서 외측고정자의 고정상태를 보인 정면도이다.Figure 4 is a cross-sectional view showing a fixed state of the outer stator in the reciprocating motor of the present invention, Figure 5 is a cross-sectional view "I-I" of Figure 4, Figure 6 shows a fixed state of the outer stator in the reciprocating motor of the present invention Front view.

이에 도시한 바와 같이 본 발명에 의한 왕복동식 모터의 외측고정자는, 환형으로 형성하고 그 안쪽에 권선코일(C)을 감아 결합하는 보빈체(11a)와, 여러 장의 스테이터코어를 겹겹이 적층하여 상기한 보빈체(11a) 외측면 양측에서 방사상으로 결합하는 복수 개씩의 코어블록(11b)과, 양측 코어블록(11b)의 외측면에 각각 지지하여 결합하는 복수 개의 코어플레이트(11c)와, 양쪽 코어플레이트(11c)를 조여 상기한 코어블록(11b)을 지지하고 그 외주면에 절연층(100)을 형성하는 수 개의 체결볼트(11d)와, 코어플레이트(11c)의 바깥면에서 상기 체결볼트(11d)에 결합하는 수 개의 체결너트(11e)를 포함한다.As shown in the drawing, the outer stator of the reciprocating motor according to the present invention is formed by stacking a plurality of stator cores and a bobbin body 11a which is formed in an annular shape and wound by winding the winding coil C therein. A plurality of core blocks 11b coupled radially from both sides of the bobbin body 11a, a plurality of core plates 11c supported and coupled to the outer surfaces of both core blocks 11b, and both core plates. A plurality of fastening bolts 11d for tightening 11c to support the core block 11b and forming an insulating layer 100 on the outer circumferential surface thereof, and the fastening bolts 11d on the outer surface of the core plate 11c. It includes several fastening nuts (11e) for coupling to.

보빈체(11a)는 플라스틱 수지와 같은 절연물을 외주면이 개구된 환형으로 형성하고, 그 내부에 소정의 선경과 감긴 수로 권선코일(C)을 다수 회 감아 고정하되 권선코일(C)은 상기한 체결볼트(11d)의 절연층(100)과 거의 접할 수 있는 만큼까지 감아 형성하는 것이 바람직하다. 또, 권선코일(C)과 상기한 코어블록(11b)과의 절연을 위하여는 그 코어블록(11b)에 대응하는 부위마다에 절연지(미도시) 등을 개재할 수 있다.The bobbin body 11a is formed of an insulator, such as a plastic resin, in an annular shape with an outer circumferential surface open, and the winding coil C is wound and fixed a plurality of times with a predetermined wire diameter and a number of turns therein, but the winding coil C is fastened as described above. It is preferable to wind and form to the extent that it can be almost in contact with the insulating layer 100 of the bolt 11d. In order to insulate the winding coil C from the core block 11b described above, an insulating paper (not shown) may be interposed between portions corresponding to the core block 11b.

코어블록(11b)은 대략 '기억자'와 이에 맞대응하도록 대략 '역기억자' 모양으로 형성하여 상기한 보빈체(11a)의 양측면에서 상호 맞대기 결합한다.The core block 11b is formed to have an approximately 'reverse memory' shape so as to correspond to the 'memory' and the butt-to-butt coupling on both sides of the bobbin body 11a.

코어플레이트(11c)는 도 6에서와 같이 원판 모양으로 형성하여 상기한 양쪽 코어블록(11b)의 바깥면에 밀착 지지하는 것으로, 그 외주연에는 원주방향을 따라 수 개의 볼트구멍(11c-1)을 형성한다. 이 볼트구멍(11c-1)은 코어블록(11b) 사이에 위치하도록 형성한다.The core plate 11c is formed in a disk shape as shown in FIG. 6 to closely support the outer surfaces of both of the core blocks 11b, and at its outer circumference, several bolt holes 11c-1 are arranged along the circumferential direction. To form. The bolt holes 11c-1 are formed to be located between the core blocks 11b.

체결볼트(11d)는 도 4 내지 도 6에서와 같이 한 쪽 코어플레이트(11c)에서 코어블록(11b)의 사이를 통과하여 다른 쪽 코어플레이트(11c)에 체결너트(11e)로 결합하는 것으로, 그 외주면 전체 또는 권선코일(C)의 범위에 해당하는 일부에는 절연튜브를 삽입하거나 절연제를 코팅처리하여 절연층(100)을 형성한다.Fastening bolt 11d is to pass through the core block (11b) from one core plate (11c) to the other core plate (11c) as fastening nut (11e) as shown in Figures 4 to 6, The insulating layer 100 is formed by inserting an insulating tube or coating an insulating material on the entire outer circumferential surface or a part corresponding to the range of the winding coil C.

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 모터의 고정자 구조는 다음과 같은 작용 효과를 가진다.The stator structure of the reciprocating motor of the present invention as described above has the following effects.

즉, 권선코일(C)을 감은 보빈체(11a)의 양측면에 코어블록(11b)을 결합하고 그 양쪽 코어블록(11b)의 바깥쪽 측면에 코어플레이트(11c)를 댄 상태에서 체결볼트(11d)와 체결너트(11e)를 이용하여 상기한 양쪽 코어플레이트(11c)를 조임으로써 상기 왕복동식 모터의 외측고정자를 조립한다.That is, the coupling bolt 11d is coupled to the core block 11b on both sides of the bobbin body 11a wound around the winding coil C, and the core plate 11c is attached to the outer side surfaces of both core blocks 11b. ) And the outer stator of the reciprocating motor are assembled by tightening both core plates 11c using the fastening nut 11e.

이때, 권선코일(C)의 외주면에 근접하여 통과하는 체결볼트(11d)의 외주면 전체 또는 일부에는 도 4 및 도 5에서와 같이 절연층(100)을 형성함에 따라 상기 권선코일(11d)과 체결볼트(11d) 사이의 절연거리(L1)를 거의 확보하지 않고도 권선코일(C)의 자기누설을 효과적으로 막을 수 있다. 이를 통해 권선코일(C)이 체결볼트(11d)와 거의 접하는 위치까지 감을 수 있어 결국 코어플레이트(11c)의 외경을 넓히지 않고도 권선코일(C)의 전체 단면적이 확대되어 모터의 직경을 늘리지 않고서도 효율을 높일 수 있다.At this time, as the insulating layer 100 is formed on the whole or part of the outer circumferential surface of the fastening bolt 11d passing close to the outer circumferential surface of the winding coil C as shown in FIGS. 4 and 5, the winding coil 11d is fastened with the winding coil 11d. The magnetic leakage of the winding coil C can be effectively prevented without almost securing the insulation distance L1 between the bolts 11d. This allows the winding coil C to be wound to a position where it is almost in contact with the fastening bolt 11d, so that the entire cross-sectional area of the winding coil C is enlarged without widening the outer diameter of the core plate 11c without increasing the diameter of the motor. Can also increase efficiency.

본 발명에 의한 왕복동식 모터의 고정자 구조는, 코어플레이트를 조여 지지하는 체결볼트의 외주면에 절연층을 형성함으로써, 권선코일을 체결볼트의 근접 위치까지 감을 수 있어 전체 코일의 단면적을 넓힐 수 있고 이를 통해 모터의 크기를 늘리지 않고서도 효율을 향상시킬 수 있다.Stator structure of the reciprocating motor according to the present invention, by forming an insulating layer on the outer circumferential surface of the fastening bolt for tightening the core plate, it is possible to wind the winding coil to the close position of the fastening bolt to widen the cross-sectional area of the whole coil This improves efficiency without increasing the size of the motor.
