Description

정류자전동기의 고정자절연물구조Stator Insulation Structure of Rectifier Motor

본 고안은 정류자전동기의 구성품 가운데 고정자철심의 절연구조에 관한 것으로서, 특히 종래에 고정자철심의 절연을 목적으로 사용된 절연물의 구조적 취약성이 원인이 되어 발생하는 스파크와 같은 내전압 불량을 방지하는데 목적이 있다.The present invention relates to the insulation structure of a stator core among the components of a rectifier motor, and particularly to prevent a breakdown voltage defect such as a spark caused by the structural weakness of an insulator conventionally used for insulation of a stator core. .

정류자 전동기의 구성품 가운데 고정자철심은 동선이 권선되는 구성품이다.Among the components of the commutator motor, the stator core is a component in which copper wire is wound.

그리고, 고정자철심과 권선된 동선 사이에는 절연물이 구성되어 상호 절연되도록 한다.In addition, an insulator is formed between the stator core and the wound copper wire to insulate each other.

이와 같이 고정자철심과 동선 사이에서 절연을 목적으로 사용되는 종래의 절연구조는 도1에 도시한 바와같이 동선(미도시)이 감겨질 수 있도록 감김홈(1)이 형성된 고정자철심(2)과, 상기 고정자철심(2)의 감김홈(1)에 결합되어 권선되는 동선과 고정자철심(2) 사이에서 절연하도록 길이가 긴 절연판부(3)가 형성된 상측 절연물(4)과, 상기 상측절연물(4)이 고정자철심(2)에 결합된 뒤에 고정자철심(2)의 저면부에 결합되어 절연 되도록 짧은 길이로 절연판부(3')를 형성한 하측절연물(5)이 구성되었다.As described above, the conventional insulation structure used for the purpose of insulation between the stator core and the copper wire includes a stator iron core (2) having a winding groove (1) formed thereon so that the copper wire (not shown) can be wound, and An upper insulator 4 having a long insulating plate portion 3 formed therebetween so as to insulate between the copper wire and the stator iron core 2 wound around the winding groove 1 of the stator core 2 and the upper insulator 4. ) Is coupled to the stator core (2), and then the lower insulator (5) is formed in which the insulating plate portion (3 ') is formed to have a short length so as to be coupled to the bottom surface of the stator core (2).

이와 같이 구성된 종래 고안의 조립과정을 살펴보면 다음과 같다.Looking at the assembly process of the conventional design configured as described above are as follows.

합성수지재로 제작된 상측절연물(4)을 고정자철심(2)에 형성된 감김홈(1) 속으로 결합한다.The upper insulator (4) made of a synthetic resin material is combined into the winding groove (1) formed in the stator core (2).

결합된 상측절연물(4)은 상측절연물(4)에 형성된 절연판부(3)가 고정자철심(2)에 형성된 감김홈(1)의 내벽에 밀착된다.The combined upper insulator 4 is in close contact with the inner wall of the winding groove 1 formed in the stator core 2 with the insulating plate portion 3 formed in the upper insulator 4.

그리고, 하측절연물(5)을 고정자철심(2)의 하부에서 결합되도록 하여 고정자철심(2)에 형성된 절연판부(3')와 고정자철심(2)의 내벽이 밀착되도록 한다.Then, the lower insulator 5 is coupled to the lower portion of the stator core 2 so that the inner plate of the insulating plate 3 'formed on the stator core 2 and the stator core 2 are in close contact with each other.

이와 같이 고정자철심(2)에 형성된 감김홈(1)의 내벽에 밀착된 상, 하측절연물(4,5)은 권선될 동선과의 사이에서 절연한다.In this way, the upper and lower insulators 4 and 5 in close contact with the inner wall of the winding groove 1 formed in the stator core 2 are insulated from the copper wire to be wound.

이와 같이 합금으로 제작된 고정자철심(2)의 표면에 합성수지재로 제작된 상,하측절연물(4,5)을 사용하여 절연하고 동선을 권선하므로서 스파크와 같은 내전압의 발생을 방지하였다.In this way, the upper and lower insulators 4 and 5 made of synthetic resin were insulated on the surface of the stator core 2 made of alloy, and the copper wire was wound to prevent generation of withstand voltage such as spark.

그러나, 이와 같이 고정자철심(2)과 동선사이의 절연을 목적으로 상,하측절연물(4,5)을 사용하는 종래의 절연 방법은 상측절연물(4)에 형성한 절연판부(3)가 두께에 대비한 길이가 길게 제작됨으로서 사출형성에 의한 진직성형 작업에 어려움이 있었다.However, in the conventional insulation method using the upper and lower insulators 4 and 5 for the purpose of insulated between the stator core 2 and the copper wire, the insulating plate portion 3 formed on the upper insulator 4 has a thickness. Since the prepared length is long, there was a difficulty in the straight molding operation by injection molding.

또한, 상측절연물(4)의 절연판부(3)가 길이에 대비한 두께가 얇은 것이 원인이 되어 동선을 권선하는 과정에서 동선을 감는 장력에 의해 절연판부(3)가 파열되어 효과적인 절연이 되지 못하는 문제점이 있었다.In addition, the insulation plate portion 3 of the upper insulator 4 is caused to have a thin thickness compared to the length, and the insulation plate portion 3 ruptures due to the tension of winding the copper wire in the process of winding the copper wire. There was a problem.

다른 실시예로서, 고정자철심(2)과 동선사이의 절연을 목적으로 폴리에스터필름과 같은 합성수지재를 일정크기로 절단하여 고정자철심(2)과 동선사이에 삽입하여 절연하는 방법을 사용하였다.As another embodiment, for the purpose of insulation between the stator core 2 and the copper wire, a synthetic resin material such as a polyester film was cut to a certain size and inserted into the stator core 2 and the copper wire to insulate it.

그러나, 이와 같은 방법 또한 동선의 감김장력에 의해 폴리에스터필름의 끝단이 취약하여 잘려나가거나 찢어지는 문제점이 있었다.However, such a method also has a problem that the end of the polyester film is vulnerable due to the winding tension of the copper wire to be cut off or torn.

따라서, 본 고안은 상기한 바와 같이 고정자철심과 상기 고정자철심에 감겨지는 동선 사이에 구성되는 절연물의 취약한 구조로 발생되는 문제점을 감안하여 고안한 것으로서, 상측절연물에 형성된 절열판부와 과다한 길이로 인한 파열의 방지와 사출성형에 의한 제작을 용이하게 하여 효과적인 절연이되도록 하는데 있다.Therefore, the present invention was devised in consideration of the problems caused by the weak structure of the insulator formed between the stator core and the copper wire wound on the stator core as described above, due to the excessive length of the heat insulation plate formed on the upper insulator To prevent rupture and to facilitate the production by injection molding to be effective insulation.

이와 같은 효과를 득하기 위한 수단으로서, 상측절연물에 형성한 절연판부를 짧게 성형하고 하측절연물에 형성한 절연판부의 길이를 연장하여 결과적으로 상,하절연물의 절연판부의 길이를 대등하게 하고 중첩부 두어 서로 결합되도록 하는데 있다.As a means for obtaining such an effect, the insulating plate portion formed on the upper insulator is shortly formed, and the length of the insulating plate portion formed on the lower insulator is extended, so that the lengths of the insulating plate portions of the upper and lower insulators are equalized, and the overlapping portions are joined to each other. To make it possible.

이와 같은 본 고안을 도2 및 도3에 도시한 바에 의하여 설명한다.This invention is described by the bar shown in FIG. 2 and FIG.

동선(미도시)이 감겨질 수 있도록 감김홈(101)을 형성한 고정자철심(102)과, 상기 고정자철심(102)에 결합되어 절연되는 상,하측절연물(103, 104)과, 상기 상,하측절연물(103, 104)에 각각 대등한 길이로 형성한 절연판부(105, 105')와, 상기 상,하측절연물(103, 104)에 형성한 절연판부(105, 105')를 상호 결합하는 중첩부를 형성하였다.The stator core 102 having the winding groove 101 formed thereon so that the copper wire (not shown) can be wound, and the upper and lower insulators 103 and 104 insulated from the stator core 102 are insulated from each other. Insulating plate portions 105 and 105 'formed at equal lengths in the lower insulators 103 and 104, and insulating plate portions 105 and 105' formed in the upper and lower insulators 103 and 104, respectively. An overlap was formed.

그리고, 중첩부는 상측절연물(103)의 절연판부(105)에 형성한 단부(106)와, 상기 단부(106)에 대응되어 결합되도록 하측절연물(104)의 절연판부(105')에 대응단부(107)를 형성하였다.In addition, the overlapping portion is formed with an end portion 106 formed in the insulating plate portion 105 of the upper insulator 103 and a corresponding end portion with the insulating plate portion 105 ′ of the lower insulator 104 so as to correspond to the end portion 106. 107).

이와 같이 구성한 본 고안은 상,하측절연물(103, 104)에 형성한 절연판부(105, 105')의 길이를 서로 대등하게 형성하고 대등하게 형성한 절연판부(105, 105')를 중첩하는 중첩부를 두어 상호 결합되도록 하였다.According to the present invention configured as described above, the lengths of the insulating plate parts 105 and 105 'formed on the upper and lower insulators 103 and 104 are equally overlapped with each other, and the overlapping insulating plate parts 105 and 105' are formed to overlap each other. Wealth was set up to be joined together.

이와 같이 결합함으로서, 고정자철심(102)에 삽입된 상,하측절연물(103, 104)은 단부(106)와 대응단부(107)에 의해 중간부에서 중첩된다.By combining in this way, the upper and lower insulators 103 and 104 inserted into the stator core 102 are overlapped at the middle by the end 106 and the corresponding end 107.

따라서, 종래에 비해 상측절연물(103)에 형성한 절연판부(105)의 길이를 짧게 할 수 있어 사출성형에 의한 비교적 정확한 성형작업을 쉽게 할 수 있는 효과를 얻을 수 있다.Therefore, compared with the related art, the length of the insulating plate 105 formed on the upper insulator 103 can be shortened, so that a relatively accurate molding operation by injection molding can be easily obtained.

또한, 상,하측절연물(103, 104)의 절연판부(105, 105')를 대등한 길이로 제작하여 중첩부에 의해 결합되도록 함으로서, 동선 권선시에 발생되는 동선의 장력이 절연판부(105, 105')의 끝단에 직접적으로 가해지는 것을 방지하므로서 절연판부(105, 105')의 갈라짐이나 찢어짐을 방지할 수 있다.In addition, the insulating plate portions 105 and 105 'of the upper and lower insulators 103 and 104 are made to have the same length and are joined by the overlapping portions, so that the tension of the copper wire generated during the copper winding is reduced. It is possible to prevent cracking or tearing of the insulating plate portions 105 and 105 'by preventing direct application to the ends of the 105').

이상에서 설명한 바와 같이 본 고안은 고정자철심과 상기 고정자철심에 감겨지는 동선 사이에 구성되는 절연물의 구조적인 문제점을 감안하여 고안한 것으로서, 상측절연물의 절연판부를 짧게 형성하고 하측절연물에 형성한 절연판부의 길이를 연장하여 결과적으로 상,하측절연물에 형성한 절연판부의 길이를 대등하게 하여 중첩부를 두어 결합되도록 함으로서, 종래의 상측절연물에 형성된 절열판부의 과다한 길이로 인한 파열의 방지와 사출성형에 의한 제작을 용이하게 하여 효과적인 절연이 되도록 한 고안이다.As described above, the present invention was devised in consideration of the structural problems of the insulator formed between the stator core and the copper wire wound around the stator core, and the length of the insulating plate portion formed on the lower insulator by shortly forming the insulating plate portion of the upper insulator. As a result, the length of the insulating plate portion formed on the upper and lower insulators is equalized so that the overlapping portion is coupled to each other, thereby preventing the rupture due to the excessive length of the heat sink plate formed on the conventional upper insulator, and facilitating manufacture by injection molding. It is designed to be effective insulation.
