“…As mentioned in [71], the acoustic noise radiated from SRMs is relatively harsher compared to induction machines and PMSMs, which limits utilizing the SRMs in noise-and vibration-sensitive applications like white goods [71]. Consequently, analyzing and reducing SRMs acoustic noise receives much attention between researchers [72]- [74].…”

Switched reluctance machines (SRMs) have recently attracted more interest in many applications due to the volatile prices of rare-earth permanent magnets (PMs) used in permanent magnet synchronous machines (PMSMs). They also have rugged construction and can operate at high speeds and high temperatures. However, acoustic noise and high torque ripples, in addition to the relatively low torque density, present significant challenges. Geometry and topology optimization are applied to overcome these challenges and enable SRMs to compete with PMSMs. Key geometric design parameters are optimized to minimize various objective functions within geometry optimization. On the other hand, the material distribution in a particular design space within the machine domain may be optimized using topology optimization. We discuss how these techniques are applied to optimize the geometries and topologies of SRMs to enhance machine performance. As optimizing the machine geometry and material distribution at the design phase is of substantial significance, this work offers a comprehensive literature review on the current state of the art and the possible trends in the optimization techniques of SRMs. The paper also reviews different configurations of SRMs and stochastic and deterministic optimization techniques utilized in optimizing different configurations of the machine.

Considerable vibration and acoustic noise limit the further application of Switched Reluctance Machine (SRM) due to its structural characteristics and working principle. An improved SRM model with double auxiliary slots (DAS) was proposed, in which the direction of the magnetic line of force was adjusted, and the radial magnetic density in the air gap was reduced by changing the local tooth profiles of the stator and the rotor. The effects of initial rotor position and turn-on angle and turn-off angle on radial Electromagnetic Force (EMF) and maximum torque were investigated. The results indicate the radial EMF and torque increase significantly with the advancement of the turn-on angle or the delay of the turn-off angle. In the orthogonal experimental design, initial rotor position, turn-on angle, and turn-off angle were taken as the factors, and the optimal set of parameters that minimized radial EMF was determined according to a greater output torque. In contrast to conventional SRM, the radial EMF of the SRM with DAS significantly reduces when the optimal set is applied.

The subject of the research is a traction switched reluctance motor with an uneven air gap. The main purpose of the work is to determine the forces of one-way magnetic attraction, evaluate and analyze these forces, develop measures to reduce the forces to an acceptable value. In the article, the forces of disbalancement and the forces of one-way magnetic attraction are considered in the relationship. The finite element method was used to determine the main parameters of the switched reluctance motor. The studies were carried out for two idealized variants of the location of the rotor rotation axis. In the first case, the axis of rotation is combined with the axis of symmetry of the stator. The second option considers the case of displacement of the axis of rotation together with the axis of symmetry of the rotor. It is determined that the resulting force of one-way magnetic attraction with an uneven air gap reaches significant values and significantly exceeds the permissible values. An algorithm for calculating the characteristics of a switched reluctance motor is proposed, which takes into account the tolerances for the manufacture of its design elements. The algorithm allows you to adjust the requirements for the bearings used, ensure the required level of reliability of the traction switched reluctance motor (SRM) and predict the level of vibration and noise.
