Comparative study of structural rigidity of induction machine and Switched Reluctance Machine

Extensive use of Induction machines (IMs) demands for comprehensive fault analysis. At the same time, the comparable cost, versatility and rigidness of Switched Reluctance Machines (SRMs) make them considerable candidates for many applications. The motivation behind this paper is to perform structural analyses for SRMs and IMs under different conditions to determine the causes of structural failures and to offer a comparative study. Stresses and deformations experienced by the machines under different scenarios such as rated speed, start-up/speed reversal and transient load change, and high speed operations, have been explored to identify the causes of structural failures, hence, facilitating application specific machine selection.
