The choice of SRM design depends on the specific application and performance requirements. Factors such as power output, torque characteristics, and efficiency will all influence the choice of SRM design. To find an optimal geometry, it is therefore necessary to determine the effect of each parameter such as rotor pole angle, stator pole angle, stator external diameter, rotor diameter, air gap length, rotor yoke, stator yoke and shaft diameter on the machine performance. For this reason, this paper discusses a comparative study of the geometric parameters influence on SRM performance. The analysis is performed by finite element simulations based on the variation of rotor inclination, air gap length, stator and rotor polar arc variations of three machine topologies such as the three-phase 12/8 SRM, three-phase 6/4 SRM and four-phase 8/6 SRM. For a reliable comparison, these machines must have the same basic dimensions (stator outer diameter, rotor outer diameter and length) and operate in the same magnetic circuit saturation. Graphical and numerical results of torque and magnetic flux for three SRM topologies are highlighted. The presented study aims to provide reliable results on the dimensions to be adjusted for various applications.

“…There are two ways to achieve these goals. One is to optimize the structure and magnetic circuit design of the motor [3,[8][9][10][11][12], and the other is to implement sophisticated motor control [4,[13][14][15][16][17][18][19][20]. Authors in [8] changed the stator and rotor geometry by attaching feet to the poles to improve the average torque production with ripple minimization.…”

Torque sharing function (TSF)-based switched reluctance motor (SRM) control is an effective approach to minimize torque ripple and maximize efficiency. This study investigated the influence of the rotor geometry to overcome the inherent torque and current tracking error of used TSFs. Parameters of the TSF were optimized according to several objectives. A finite element method simulation model of the motor was built and verified to evaluate the objective functions. The optimization result is a set of functions that calculate optimal values of the start angle and overlap angle of the sinusoidal TSF for every operating point of the motor. Different objectives, including efficiency and a torque ripple, lead to different functions for calculating start and overlap angles. The research showed that if efficiency is the most important objective, it is possible to determine a suitable rotor pole geometry. For other criteria, the choice of rotor geometry is not so clear-cut and requires consideration of the SRM operating modes.

“…When designing rotating electrical machines with large power-to-weight ratio and high efficiency, it is advantageous to introduce high performance materials, while taking into account environmental and financial costs. In this context, SRM [1] are suitable candidates giving the fact they are magnet free and have no winding at the rotor [2]. They are known to be robust and reliable [3] even if they operate in harsh environments.…”

This paper deals with the development of a simplified numerical model with the aim of assessing the impact of using grain-oriented electrical steel (GOES) in switched reluctance machine (SRM) on its performance. Different grades of steel are studied to firstly analyse their impact on the inductance and the electromagnetic torque change. Then, both the simplified model and the steel grades helped determine the level of contribution of anisotropy and high permeability individually. In this paper, the impact on electromagnetic torque is evaluated along with a local analyses of the flux lines distribution and the numerical model allows to draw conclusions on the device performance when anisotropy is introduced. Although the GOES numerical model used for finite elements simulations is not a fully developed model, it is adequate enough for our study. The originality of this paper lies in the fact that the developed model is relatively simple and appropriate enough to investigate all the electromagnetic phenomena and draw conclusions which can be applicable to a more complex and time-consuming electromagnetic device. The second original aspect is the introduction of GOES in an axial flux SRM (AFSRM).
