Many automotive components for power generation such as motors and alternators have been widely using ferrite magnets. To ensure a high level of efficiency could be achieved in an alternator, the assembled magnets must be in good enough durability. Recently, some hairline cracks have been found on the magnet produced by manufacturers in Korea. Thus, there is an increasing concern that some of the magnets produced could cause further problems after being assembled in the alternator. Based on the standard alternator test (RS0008 : 2006), this paper has developed an accelerated failure-free test for magnets in alternator to demonstrate that assembled magnets will meet durability objective specified by the manufacturer. This guarantees the target life of the magnet with 90 percent reliability and 90 percent confidence level (R90C90). Temperature and rotation speed were selected as accelerated stress factors.

재제조는 사용 후 제품을 체계적으로 회수하여 분해, 세척, 검사, 보수조정, 재조립 등의 공정을 거쳐 원래의 성능을 유지할 수 있도록 만드는 과정이다. 자동차 교류발전기를 재제조하기 위해서는 재제조품에 요구되는 품질 및 신뢰성을 확실히 달성하기 위하여 공정 별 복잡한 작업들에 대하여 세부적인 사항들을 결정하고 이를 설계하는 일이 중요하다. 본 연구의 목적은 재제조를 위한 최적의 공정설계를 위해 FMEA를 활용한 체계적인 가이드라인을 제시하여 재제조품의
