이하, 본 발명에 따른 회전자(40)를 도면을 참조하여 보다 상세히 설명한다.Hereinafter, the rotor 40 according to the present invention will be described in more detail with reference to the drawings.

도 2 및 도 3을 참조하면, 본 발명에 따른 회전자(40)는 다수의 라미네이트(41)가 상하방향으로 적층되어 형성된 코어(42), 코어(42)의 외주면에 마련된 마그네트(43)를 구비한다. 2 and 3, the rotor 40 according to the present invention includes a core 42 formed by stacking a plurality of laminates 41 in a vertical direction and a magnet 43 provided on an outer circumferential surface of the core 42. Equipped.

마그네트(43)는 다수개로 마련되어 극을 달리하도록 교번되게 설치되며, 마그네트(43)간의 자기적 간섭을 피하기 위해 각 마그네트(43)는 원주방향으로 상호 이격되도록 배치된다. 이를 위해 코어(42)는 외측으로 돌출되어 각 마그네트(43) 사이에 마련되는 돌출부(42a)를 구비하게 된다.The magnets 43 are provided in plural numbers and alternately installed to different poles. In order to avoid magnetic interference between the magnets 43, the magnets 43 are disposed to be spaced apart from each other in the circumferential direction. To this end, the core 42 protrudes outward and includes a protrusion 42a provided between the magnets 43.

또한, 마그네트(43)는 상하단에 원주방향으로 설치홈(43a,43b)이 형성되고, 이 설치홈(43a,43b)에는 고정캡(44,45)이 씌워져 설치되게 된다. In addition, the magnet 43 has an installation groove (43a, 43b) is formed in the circumferential direction in the upper and lower ends, the fixing cap (44, 45) is covered with the installation groove (43a, 43b).

즉, 고정캡(44,45)은 마그네트(43)의 상단에 설치되는 상부 고정캡(44)과, 하단에 설치되는 하부 고정캡(45)으로 구분되는데, 이러한 두 고정캡(44,45)을 통해 코어(42)와 마그네트(43)가 서로 결합을 이루게 되며, 두 고정캡(44,45) 및 마그네트(43) 내측에 위치한 라미네이트(41)는 별도의 체결부재없이 적층된 형상을 유지할 수 있게 된다. 여기서 미 설명된 부호 44a,44b는 회전축(32)이 통과할 수 있도록 고정캡(44,45)의 중심측에 형성된 중공부를 지칭한다.That is, the fixing caps 44 and 45 are divided into an upper fixing cap 44 installed at the top of the magnet 43 and a lower fixing cap 45 installed at the bottom thereof. Through the core 42 and the magnet 43 is coupled to each other, the two fixing caps 44 and 45 and the laminate 41 located inside the magnet 43 can maintain a stacked shape without a separate fastening member Will be. Reference numerals 44a and 44b, which are not described herein, refer to hollow portions formed at the center of the fixed caps 44 and 45 so that the rotation shaft 32 can pass therethrough.

한편, 고정캡(44,45)을 설치홈(43a,43b)에 설치하는 경우, 고정캡(44,45)의 내경은 설치홈(43a,43b)이 형성된 마그네트(43) 단부의 외경보다 다소 작게 마련되는 것이 바람직하며, 이에 의해 설치홈(43a,43b)이 형성된 단부는 고정캡(44,45)에 압입 고정되게 된다. 또, 보다 견고한 설치를 위해 도 4에 도시된 바와 같이, 고정캡(44,45) 외주면의 단부가 코킹되어 마그네트(43)를 압착 지지할 수도 있다.On the other hand, when the fixing caps 44 and 45 are installed in the installation grooves 43a and 43b, the inner diameters of the fixing caps 44 and 45 are somewhat smaller than the outer diameters of the ends of the magnets 43 where the installation grooves 43a and 43b are formed. It is preferable to be provided small, whereby the end formed with the installation grooves (43a, 43b) is press-fit fixed to the fixing cap (44, 45). In addition, as shown in Figure 4 for a more robust installation, the end of the outer peripheral surface of the fixed cap (44, 45) may be cocked to support the magnet 43 by pressing.

다음에는 본 발명에 따른 밀폐형 압축기의 회전자(40) 조립 과정 및 그에 따른 효과를 설명한다.Next will be described the rotor 40 assembly process of the hermetic compressor according to the present invention and the effects thereof.

먼저, 다수의 라미네이트(41)를 적층하여 코어(42)를 형성하고, 코어(42)의 외주면에 마그네트(43)를 배치한다. 이때 마그네트(43)는 코어(42)에 형성된 각 돌출부(42a) 사이에 안착되게 하며, 반경방향으로 서로 교번되는 극을 갖도록 배치시킨다.First, a plurality of laminates 41 are laminated to form a core 42, and a magnet 43 is disposed on an outer circumferential surface of the core 42. At this time, the magnet 43 is to be seated between each protrusion 42a formed in the core 42, it is arranged to have poles alternate with each other in the radial direction.

이후, 마그네트(43)의 설치홈(43a,43b)에 고정캡(44,45)을 설치함으로써 코어(42)와 마그네트(43)를 서로 견고히 결합시키게 된다.Subsequently, by installing the fixing caps 44 and 45 in the installation grooves 43a and 43b of the magnet 43, the core 42 and the magnet 43 are firmly coupled to each other.

이와 같이, 본 발명에 따른 밀폐형 압축기의 회전자(42)는 마그네트(43)가 고정캡(44,45)만을 통해 코어(42)에 견고히 고정되게 되므로, 종래 압축기에 있어서 마그네트(43)의 외주면을 감싸 고정하는 별도의 원통부재가 요구되지 않게 된다.As such, the rotor 42 of the hermetic compressor according to the present invention has the magnet 43 being firmly fixed to the core 42 only through the fixing caps 44 and 45, and thus the outer peripheral surface of the magnet 43 in the conventional compressor. There is no need for a separate cylindrical member to wrap and secure the cover.

이에 따라, 자속을 형성하는 고정자(31)와 회전자(40) 코어(42) 간의 거리를 최소화할 수 있게 되어 압축기의 구동효율이 향상되는 효과가 있다.Accordingly, the distance between the stator 31 and the rotor 40 core 42 forming the magnetic flux can be minimized, thereby improving the driving efficiency of the compressor.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 밀폐형 압축기는 회전자코어 및 마그네트가 고정캡을 통해 서로 결합되게 된다.As described in detail above, in the hermetic compressor according to the present invention, the rotor core and the magnet are coupled to each other through a fixing cap.

이에 따라, 마그네트 외주면을 감싸 고정하는 종래 원통부재가 요구되지 않 게 됨으로 자속을 형성하는 고정자와 회전자의 전기강판 간의 거리를 최소화 할 수 있게 되어 압축기의 구동효율이 전체적으로 향상되는 효과가 있다.Accordingly, since the conventional cylindrical member surrounding the magnet outer circumferential surface is not required, the distance between the stator and the electric steel plate of the rotor forming the magnetic flux can be minimized, thereby improving the driving efficiency of the compressor as a whole.

또한, 마그네트에 설치되는 고정캡을 통해 복수의 라미네이트는 별도의 체결부재없이 적층된 형상을 유지할 수 있게 되므로 부품수를 감소하고 작업공정을 줄일 수 있게 되는 효과가 있다.In addition, the plurality of laminates through the fixing cap installed on the magnet can maintain the stacked shape without a separate fastening member, thereby reducing the number of parts and reducing the work process.
