The present invention provides an apparatus for diagnosing a DC motor fault of a gate door for a railway vehicle, which performs frequency conversion (converting a signal waveform in accordance with time into a frequency domain) with respect to a measured voltage and a measured current, checks whether an abnormal frequency exists in a frequency component (type of waveform, etc.) through the frequency conversion at the same time, and diagnoses a fault when confirming the occurrence of an abnormality in both a voltage and a current, thereby carrying out a high reliable fault diagnosis and quick fault diagnosis.

    본 발명은 측정 전압과 측정 전류에 대하여 주파수 변환(시간에 따른 신호 파형을 주파수 영역으로 변환)을 수행함과 더불어 이러한 주파수 변환을 통해 확인되는 주파수 성분(파형의 유형 등)에서 이상 주파수가 존재하는지를 동시에 확인하고, 이러한 확인을 통해 전압 및 전류 모두에서 이상이 발생되었을 경우 결함으로 진단함에 따라 높은 신뢰성의 결함진단이 이루어질 수 있도록 하면서도 빠른 결함 진단이 이루어질 수 있도록 한 철도차량용 출입문 도어의 직류모터 결함진단장치가 제공된다.
