초록

최근 저소음, 고속, 고추력의 반송장치가 요구됨에 따라 영구자석 선형동기전동기가 대두되고 있으나 반송경로 전장에 전기자를 설치하는 선형 동기전동기의 특성으로 인해 장거리 반송장치에 적용시 설치비용의 증가를 가져온다. 따라서 우리는 전기자를 분산시켜 배치하는 방법을 제안하여 비용증가의 문제점을 해결하고자 하였다. 하지만 가동자의 진행시 분산배치된 전기자 사이를 통과하게 되면 전기자의 불연속 구간인 단부에 의해 디텐트력이 발생하여 추력 맥동이 발생하고 기기 성능저하와 소음, 진동의 원인이 된다. 따라서 본 논문에서는 단부에 의한 영향을 저감하기 위해 전기자 끝단의 치 높이와 보조치 형상에 따른 디텐트력의 특성을 파악하고 다구찌의 실험계획법을 이용하여 단부 효과를 가장 저감할 수 있는 형상을 제안하였다.

Recently, the permanent magnet linear synchronous motor as low noise, high speed and high thrust force transportation system has been proposed but this motor causes an increase of material cost because of its characteristic arranging the armature on the full length of transportation lines when this system is applied to the long distance transportation system. Therefore, we suggested discontinuous arrangement method of the armature to solve this problem. However, Detent force which causes thrust force ripple generating noise, vibration and decline of performance is generated when a mover pass between the armatures. Thus, in this paper, we examined characteristic of detent force to reduce the end edge effect according to the end edge teeth's height and auxiliary teeth and suggested the shape that can the most reduce the detent force.
