유도전동기 회전자 바 고장 자동 진단 모니터링 시스템 개발

In this study, using LabVIEW, rotor bar failure was diagnosed automatically. Firstly, rotor slot harmonics were estimated to get the rotational speed of the motor and the characteristic frequency of rotor bar fault was extracted. The amplitude of the characteristic frequency of failure was compared to that of normal and rotor bar failure was diagnosed automatically.
