摘要

In recent times Reluctance Synchronous Motors (RSM) have gained popularity in variable speed market due to their advantages like low cost, rugged construction, minimum winding losses, and zero speed regulation. Usually in RSM the direct axis air gap is kept low to achieve improved performance. Therefore, eccentricity fault detection in RSM becomes vital. Static eccentricity, one of the two types of eccentricity, is present even in a newly manufactured motor. So far not much work has been reported in literature with respect to modeling a salient pole machine under static eccentric condition. In this paper a Modified Winding Function Approach (MWFA) based model is developed and a characteristic frequency corresponding to static eccentric condition is identified. Finally a non-invasive method based on Motor Current Signature Analysis (MCSA) and residue elimination technique is used to detect static eccentricity in a salient pole RSM in an unambiguous manner.
