    Air Gap Length and Maximum and Minimum Inductance of A Double-Salient Reluctance Machine (DSRM) using The Developed Analytical Algorithm
    (International Journal on Electrical Engineering and Informatics, 2022-03-12) Enesi Asizehi Yahaya; Ajah Victor; Emenike Chinedozi Ejiogu
    In this paper an algorithm is developed to predict the maximum and minimum inductance of an optimized pole arc of a fabricated double salient reluctance machine (DSRM). The developed analytical algorithm investigates the air gap length at the maximum and minimum inductances. These are achieved through the machine rotor pole arc, stator pole arc, bore diameter, back iron thickness, rotor yoke thickness, stack length, and rotor pole diameter. The validity of the newly developed analytical procedures for predicting the maximum and minimum inductances was evaluated using the measurements obtained from the machine prototype. There was a good correlation between the analytical and experimental results. Inductances and air gap lengths of 2/2 DSRM of equal stator and rotor pole width and stator pole width greater than the rotor pole width were investigated and analyzed using the developed algorithm. A second existing DSRM with different numbers of stator and rotor poles whose inductances have been known and compared with finite element analysis (FEA) is chosen to verify the algorithm developed. The 2/2 DSRM’s potential to sustain oscillation during energy conversion from mechanical energy to electrical energy is investigated
