Review of Frequency Response Analysis for Testing of Rotating Electric Machines

초록

With the increasing trend in the electrification of transportation and renewable energy sources, the reliability of rotating electric machines is becoming crucial, and this has driven active research on identifying new test methods. There has been an increasing interest in evaluating the effectiveness of frequency response analysis for testing rotating machines as it has been proven to be a convenient, noninvasive and versatile test. Active research on evaluating the feasibility of applying frequency response analysis for maintenance testing and quality assurance of rotating machines and components has been performed over the last 7-8 years. The purpose of this article is to provide a summary and critical analysis of the latest research published on the application of frequency response analysis (FRA) to rotating electric machines. The challenges and recommendations for future work are given based on a critical evaluation of the literature to support research and development efforts towards industrial needs.
