“…2. Due to the non‐linear nature of the flux densities, the losses were quantified through the Fourier series expansion with mathematical models and it was observed that two‐thirds of the stator back iron contributed to more than 60% of the total iron loss in the motor [17–22].…”

Some key features to be satisfied by electric motors catering a wide range of applications are high specific power, lower manufacturing cost, rugged construction, and fault‐tolerant operation. Switched reluctance motor is one such motor technology satisfying all the above requirements and is an emerging competitor to the induction and permanent magnet motors in domestic, industrial and electric vehicle applications. The present‐day research on this motor is moving towards improving efficiency at lower speeds, power density, and the torque density. Certain challenges in achieving the same are (a) minimising the losses, (b) mitigation of torque ripple, noise, and vibration, and (c) material advancements. A review based on the estimation and mitigation techniques of each of these over the past three to four decades has been dealt with in this study. The salient features and results in each section provide a clear understanding of how each of these challenges can be overcome in the aspect of design and control strategies.

“…Switched reluctance motors (SRMs) are widely used in different applications such as new generation of transportation. Simple and strong structure, high efficiency, low weight and small size due to the absence of rotor windings, variable speed operations, high torque to inertia ratio, reliability, relatively low manufacturing costs and fault permissibility of SRM are reasons for choosing a SRM in industry especially in electrical vehicles [1]. High starting torque for initial acceleration, high average torque, and high efficiency to save battery for a longer operating time are the main factors to design such a practical motor [2].…”

“…Various researches on geometries and drive design of SRM and generators have been successfully investigated in the past. In [1], a FEM analysis showed that the effects of phase current chopping of a sample 8/6 SRM could reduce the core loss about 50%. Nevertheless, no exact explanation about the frequency and amplitude was provided.…”

In this paper, the robust optimization shape and drive of switched reluctance motors (SRMs) are discussed using robust particle swarm optimization (RPSO). The shape optimum goal of the algorithm was found for maximum torque value and minimum torque ripple, following changing the geometric parameters. The drive optimum aim of the algorithm was found minimum torque ripple, following changing the current profiles. The optimization process was carried out using a combination of RPSO and Finite Element Method (FEM). Fitness value was calculated by FEM analysis using COMSOL 4.2, and the RPSO was realized by MATLAB 2011. The proposed method has been applied to two case studies and also compared with seeker optimization algorithm. The results show that the optimized SRM using RPSO has higher torque value, lower torque ripple and higher robustness, indicating the validity of this methodology for SRM design and implementation.
