Abstract

In recent years, Switched Reluctance Machines (SRMs) have attracted increasing interest in Electric Vehicles (EVs) applications due to the fluctuating prices of rare earth magnets (Permenant Magnets - PMs) used in Permanent Magnet Synchronous Machines. PMSMs). It is also characterized by a solid and strong construction, in addition to that it works at high speeds and high temperatures. However, the negatives are the loud noise and high torque ripples. In addition to the relatively low torque density, it poses great challenges for researchers in finding appropriate solutions. Where engineering structure optimization techniques are used to overcome these challenges and enable impedance switched machines (SRMs) to compete with permanent magnet synchronous machines (PMSMs). On the other hand, it is possible to improve the distribution of the materials used in the engineering structure of the key impedance machines within a certain design space within the machine structure by using the engineering structure improvement techniques. This study presents a review on techniques for improving the geometry of SRMs to improve machine performance, since optimizing machine geometry and material distribution at the design stage is of great importance in improving the performance and characteristics of SRMs
