I. Introduction
Switched reluctance motors (SRMs) have been recognized for their simple and robust construction. They eliminate the permanent magnet, brushes, and coil windings in the rotors. As a result of their structural simplicity, SRMs offer several advantages of reliability, high-speed mode and low cost [1]–[2]. These attractive factors make SRMs to be considered as one of the candidates to replace the permanent magnet synchronous motors. Despite their acceptance in industrial applications, system reliability remains one of the key concerns. When a fault arises in the industrial process, it brings about a health or safety problem as well as an increased loss due to the shutdown of the process. Thus, a correct diagnosis for the failures of the drive system is very important to avoid harmful accidents and guarantee a continuity of operation.
