Claims (1)
- 설정된 상호 인덕턴스 값을 이용하여 무효전력 지령치를 연산하는 단계와; 전동기의 무효전력을 검출하여 무효전력 검출치를 획득하는 단계와; 상기 무효전력 지령치와 무효전력 검출치의 차를 구해, 그 차가 0이면 실제 상호 인덕턴스와 설정된 상호 인덕턴스의 값이 동일한 것으로 판단하고, 0이 아니면 상기 무효전력 지령치와 무효전력 검출치의 차가 0이 되도록 설정된 상호 인덕턴스의 값을 조절하여, 그 조절된 상호 인덕턴스의 값을 실제 상호 인덕턴스의 값으로 인식하는 단계로 이루어진 것을 특징으로 하는 유도전동기의 상호 인덕턴스 측정방법.
