Abstract: 본 발명은 전동기(Starter motor)용 모터에 사용되는 정류자는 코일과의 접합 특성상 "ㄱ"자형(Riser type)의 형상을 요구하며, 이러한 정류자 편을 생산하는 방법으로는 인발과 프레스를 이용하여 형상화하는 방법과, 단조방식의 열간 및 냉간 단조의 프레스를 이용한 방법이 있으며, 인발방식의 작업은 [도 3] 에서와 같이 여러 가지의 인발 다이스를 이용하여 순차적으로 동선을 인발하여 일정한 형상을 만들어낸 다음 프레스를 이용하여 일정한 크기와 모양으로 형상화하며, 단조방식은 프레스를 사용하여 [도 4] 와 같이 일정한 모형으로 형상화하는 방법으로 인발 생산방법은 고가의 원재료 동선의 낭비가 많은 단점이 있고, 원자재의 손실이 커 제조 원가상승에 큰 부담요인을 안고 있으며 [도 5] 의 그림 중 점선으로 표기한 부분이 인발과 프레스를 이용하여 작업할 경우 스크랩으로 처리되는 원자재의 손실부분을 표기 했고 , 또한 단조 방식의 경우 공정이 복잡하고 재료의 변형으로 인발방식보다 내구성이 떨어짐으로 소비자로부터 외면을 받고 있으며 인발방식과 동일하게 편을 제작하고 절연체와 교번하며 조립하는 번거로움이 많았다, 그러나 본 발명은 동선을 이용한 정류자의 생산방식에서 탈피하여 서로 다른 크기의 속이 빈 중공동봉을 이용해 절단하고, 용접하여 일정한 형상을 만들고 내부에 보강 링이 들어가는 형식의 정류자는 열간 단조의 방법으로 정류자를 생산하는 방법과, 또 다른 방법으로는 프로파일이라고 하는 일정한 형상의 동판을 만들어 생산하는 방법이다, 이런 발명은 공정개선과 생산성 향상 및 원가절감에 주안점을 두고 개발하였으며,  기존의 생산 방식과는 전혀 다른 생산 방법으로 공정은 다음과 같다. 
     기존의 인발형식의 작업공정 [도 3] 을 예를 들면 
     동선의 구입 / 압연S / 열처리 / 인발7,6 / 열처리 / 인발5,4 / 열처리 / 인발3,2,1,F / 절단 / 세척 / 건조 / 조립 / 성형 / 열처리 / 기계가공 / 검사 / 포장의 과정으로 공정이 전개된다. 
     기존의 단조형식의 작업공정 [도 4] 을 예를 들면 
     동선의 구입 / 열처리 / 절단 / 가열 / 단조 / 세척 / 건조 / 조립 / 성형 / 열처리 / 기계가공 / 검사 / 포장의 과정으로 공정이 전개된다. 
     새로운 정류자 보강 링이 없는 작업공정 [도 2] 의 예를 들면 
     속이 빈 동봉의 구입 절단 / 가열 / 단조 / 용접 / 성형 / 열처리 / 기계가공 / 검사 / 포장으로 구성되며, 보강 링을 쓰는 경우 성형공정 앞에서 보강 링을 삽입하여 성형하도록 되어 있다. 
     본 발명의 분리 용접형식 정류자는 인발방식보다, 최대 35-43％의 동선의 원자재를 절감할 수 있고, 단조방식에 비하여 공정이 극히 단순하여 생산 효율을 극대화 할 수 있었고 종전의 두 작업방법에 비하여 본 발명품은 조립과정이 없이도 제품을 생산할 수 있는 장점이 있었다. 
     이런 정류자를 고안 개발한 목적은 고가인 동이 스크랩으로 잘려나가는 량이 많아 이를 줄이고 공정을 개선하고자 착안한 것이 조립이 필요 없는 일체형의 정류자를 고안하고 개선하여 속이 빈 동봉의 소재를 이용하여 용접형식의 정류자를 발명하게 되었다. 
     기존의 봉을 사용하여 생산하는 정류자는 소형 후크(연결고리 형식)타입의 용으로 사용하고 있으며, 이보다 큰 "ㄱ"자형 라이자를 형상의 정류자는 인발다이스를 통과한 동선을 프레스를 이용해 일정한 모양으로 편을 제작하는 인발방식과 동선을 열간 또는 냉간 단조기를 통해 핀을 제작하는 단조방식으로 정류자를 제작해왔으며, 두 가지 방법 모두 제조 공정이 길고 스크랩의 발생이 많아 원가 상승요인이 있었고, 특히 냉간 단조방식은 소재의 변형과 크랙으로 내구성에 취약함이 있었다, 또한 종전의 분리형 [도 6] 정류자는 인발하고 열처리한 동선을 프레스를 이용하여 절단하고 세척과 건조과정을 거친 다음 편마다 침봉 구멍을 가공해 동선을 조립하고 또다시 세그먼트 조립품에 절연 판을 조립하고 연장침봉을 절곡하는 번거로움이 있었고 몸통과 라이자의 정확한 치수를 제어하기 힘들었으며, 절연판과 연장침봉의 크기와 두께 및 조립의 직각도역시 제어하기 힘들었고 이는 회전자의 밸런스에 지대한 영향을 주었으며, 신선(동선을 압입 / 휴징 이라고도 함)하기 힘들었다. 
     그러나 새로 개발된 정류자의 생산방법은 "ㄱ"를 두 개의 봉을 절단하여 용접하고 절개하여 성형하는 방법으로 절연체 및 조립 공정이 필요 없어 공정이 단순하며 스크랩의 량이 최소화되며 공정개선 효과와 원가 경쟁력을 동시에 확보할 수 있다. 
     
     분리용접형식 정류자, 조립이 필요 없는 정류자, 절연체가 필요 없는 정류자.
