Park`s Vector Approach의 지수함수에 기반한 유도전동기 고장진단

This paper presents a methodology to detect fault of induction motor based on exponential of Park`s vector approach, such as d-axis and q-axis from Motor current signature analysis(MCSA). Park`s vector Approach has difficulties such as detect and diagnose of small current value, so authors develop a methodology which use exponential function and Fast Fourier Transform. By using this methodology, distorted diagram on two-dimensional plane is shown.
