초록

권선 결함을 검출하기 위하여 다양한 방법들이 적용되어 왔는데, 최근에는 전류 신호를 이용한 결함 검출 방법에 대한 연구들이 많이 이뤄지고 있다. 전류 신호는 전동기의 권선 결함에 대한 주요한 정보를 담고 있으며 본 연구에서도 BLDC 전동기의 권선 단락을 검출하기 위하여 전류 신호로부터 결함 특징을 추출하는 방법을 적용하였다. 본 연구를 통해 전류 신호로부터 결함 특징을 추출하는데 가장 적절한 방법을 시뮬레이션 및 실제 측정 데이터를 통해 비교 평가하고자 하였다.

Several methods have been applied to detect winding faults (turn-to-turn short). The representative approaches have been focusing on current signals. The current signal can give important information to extract features and to detect faults. In this study, current sensors were installed to measure signals for fault detection of BLDC motors. Therefore, it is necessary to select proper feature extraction methods among the popular methods that use current signals.
