Static eccentricity fault diagnosis in switched reluctance motor

In this paper a novel view of airgap magnetic field analysis of Switched Reluctance Motor under static eccentricity to provide the precise fault diagnosis based on three-dimensional finite element method is presented. Analytical nature of this method makes it possible to simulate reliable and precise model by considering the end effects and axial fringing effects. The results of the three-dimensional finite element analysis of 6/4 switched reluctance motor such as flux linkages, terminal inductance per phase and mutual inductance for various eccentric motor conditions are obtained and analyzed. These results present useful information regarding to the detection of static eccentricity.
