Abstract

In order to have higher efficiency, performance and reliability the regular monitoring of an electrical motor is required. This article elaborates the novel approach for air-gap magnetic field analysis of switched reluctance motor in case of rotor cracks and rotor tilt around its shaft axis. The fault diagnosis is illustrated on the basis of a 3-D model of the SRM using of a technique known as finite element analysis (FEA). The flux linkage analytical equations are used for the derivation of inductance expressions. The results obtained from the 3-D FEA of a SRM having 6 stator and 4 rotor poles shows the variation of mutual inductance with the cracked rotor conditions and the tilting of rotor shaft. The results obtained explain the usefulness for the detection of cracked rotors and shaft tilting.
