| Title: | Multi-objective Optimization Design of Modular Linear Rotary Switched |
| Abstract: | In order to combine the advantages of modularity for motor power density enhancement, this paper proposes a three-phase modular linear rotary switched reluctance machine (MLRSRM) with both segmented stator and rotor. In order to increase the torque characteristics of the motor, this paper proposes a multi-objective optimization design of MLRSRM based on the Taguchi method. The static average electromagnetic torque and electromagnetic thrust of the motor are taken as the optimization objectives, and the four ontological parameters (stator pole arc, rotor pole arc, rotor module radial depth and rotor module edge width) that have a greater impact on the MLRSRM optimization objectives are selected. The Taguchi method is used to optimize the motor, determine the optimized structural parameters and verify them by finite element analysis software. The finite element simulation results demonstrate the effectiveness of the described optimization method on the structural design of the MLRSRM. This paper has certain theoretical significance and reference value for the optimal design of MLRSRM. |

| Title: | Multi-objective Optimization Design of a DSSRM with U-type Modular Segmental-stator Structure |
| Abstract: | A U-type modular double stator switched reluctance motor (DSSRM) which has the merit of high-power density is optimized in this paper. Taking average torque, torque smoothing coefficient and efficiency as objectives, sensitivity analysis on DSSRM is investigated and discussed to select significant geometric variables. On the basis of the initial structural parameters, the multi-objective optimization design is processed by adopting a fuzzy iteration optimization algorithm with weight determination. After the determination of decision result of each structure parameter, the best dimension scheme of the DSSRM is concluded. Moreover, the final scheme proves to perform better than the initial scheme by finite element (FE) analysis. Finally, a prototype motor is manufactured and the experimental results validate the improvement of the DSSRM performance. |

| Title: | Design and Optimization of Hybrid Excitation Switched Reluctance Motors for Electric Transportation Vehicles |
| Abstract: | To improve the torque characteristic of hybrid excitation switched reluctance motors (HESRM), the structure and excitation current of HESRM are comprehensively studied. First, a novel structure is introduced to HESRM, in which pole pieces are added to the rotor salient pole to reduce output torque ripple. The effect of different structural parameters in HESRM is studied by finite element model (FEM). To evaluate the torque characteristic of the machine, mean torque and torque are chosen as key evaluation factors of HESRM. To achieve a quick and accurate optimization process, an artificial neural network (ANN) based prediction model is built according to FEM results, in which system structure is employed as input components and evaluate factors are employed as output components. Then, genetic algorithm (GA) is designed for HESRM structure optimization. With improved GA and ANN prediction models, the torque performance of HESRM can be further improved. Finally, experimental and simulation results are given to validate the accuracy of machine design. |

| Title: | Design of Gravity Energy Storage Switched Reluctance Machine Based on Artificial Intelligence Optimization Algorithm |
| Abstract: | To address the operational characteristics of gravity energy storage systems, this paper proposes an optimized design method for a switched reluctance machine (SRM) suitable for a gravity energy storage system. A novel 12/8 salient stator tooth structure is introduced to enhance performance in both energy storage and power generation modes. Four key optimization objectives are defined: average torque and torque ripple in the energy storage state, as well as generation power and efficiency in the power generation state. The influence of structural parameters on these optimization objectives is systematically analyzed and a multiojective optimization of the structural parameters is conducted by the Multi-Objective Grey Wolf Optimizer (MOGWO) algorithm. Finite element analysis (FEA) is performed to evaluate the electromagnetic characteristics of the optimized design. The results demonstrate that the proposed SRM achieves superior performance compared to the traditional 12/8 SRM, making it well-suited for gravity energy storage applications. |

| Title: | Dynamic Evolutionary Control Strategy for Switched Reluctance Generator |
| Abstract: | This paper introduces a double-stator novel switched reluctance machine employed as a wind generator. To stabilize the fluctuating power output of an off-grid wind power storage system and maintain the bus voltage stability of the power generation system, a dynamic evolutionary control strategy utilizing closed-loop bus voltage regulation is proposed. This includes constructing a multi-objective optimization function with four parameters: power generation efficiency, output voltage, torque smoothness coefficient, and power smoothness coefficient. These parameters serve as the basis for mode selection in multi-mode operation. Furthermore, in order to further enhance the system’s power generation efficiency, a real-time optimization method based on efficiency optimization for the commutation angle is designed. The integration of these two methods results in a multi-mode operation method for double-stator switched reluctance generator (DSSRG) based on efficiency optimization control. Simulation and experimental results validate the feasibility and effectiveness of the new DSSRG system and its control methods. This research holds significant importance for the application of DSSRGs in the field of power generation. |

| Title: | Modeling and Analysis of Equivalent Magnetic Network Model for Novel Asymmetric Rotor Permanent Magnet-assisted Synchronous Reluctance Motor |
| Abstract: | This paper presents a novel asymmetric rotor permanent magnet-assisted synchronous reluctance motor (NAR-PMa-SynRM) designed to enhance torque output and reduce torque ripple by employing unconventional methods compared to traditional approaches where permanent magnets are embedded within magnetic barriers. In this design, tile-shaped permanent magnets are embedded along the rotor d-axis, coupled with an asymmetric magnetic barrier structure. To streamline the motor design process, a nonlinear equivalent magnetic network (EMN) model tailored to the distinctive structure of the NAR-PMa-SynRM is proposed. However, modeling the complex magnetic barrier structure poses a significant challenge in magnetic network modeling. To address this challenge, an effective method for representing the magnetic barriers equivalently is proposed to enhance modeling accuracy. Finally, the effectiveness of the proposed equivalent barrier method and magnetic network model is validated by comparing air gap magnetic flux density results obtained from finite element and magnetic network simulations. |

| Title: | Design and Analysis of Modular Transverse Flux Dual-rotor Switched |
| Abstract: | The present study proposes a novel modular transverse flux dual-rotor switched reluctance motor (MTF-DRSRM), which integrates the operational principles of switched reluctance motors (SRMs) with the structural advantages of transverse flux machines (TFMs). The motor employs H-shaped modular stator cores and segmented rotor discs with embedded pole modules, employing toroidally-wound concentrated windings for excitation. Compared to conventional SRMs, the MTF-DRSRM leverages the transverse flux configuration to enable flexible decoupling of electric and magnetic loads. This design effectively enhances torque density and operational efficiency, making it suitable for high-performance drive applications such as electric vehicles. This paper introduces the fundamental structure, operational principles, and electromagnetic design methodology of the MTF-DRSRM. Due to the three-dimensional distribution of the motor’s magnetic field, 3D magnetic field computation using finite element analysis (FEA) is employed to calculate key parameters, including magnetic flux linkage and torque characteristics. The design validation is performed by comparing theoretical parameters with 3D-FEA simulation results, ensuring accuracy and reliability. This work provides a robust theoretical foundation and empirical data for further optimization and practical implementation of the proposed motor topology. |

| Title: | Analysis of Magnetic Circuit Characteristics of Axial-radial Hybrid Flux Switched Reluctance Motor |
| Abstract: | In order to enhance the torque output capability of Switched Reluctance Motors (SRM), this paper proposes two types of axial-radial mixed magnetic flux SRM topological structures with wide-narrow pole and same-tooth pole by combining the respective advantages of axial and radial magnetic fluxes. Two identically shaped axial stator structures are used, distributed on both sides of the rotor, forming an axial magnetic flux path with the central rotor. Simultaneously, on the outer side of the rotor, a radial stator structure is distributed, sharing the rotor to form a radial magnetic flux path. By using equivalent magnetic circuit analysis methods analyzing the flux linkage characteristic in a special position of the two topological structures, the superior torque performance of the axial-radial mixed magnetic flux SRM topology is determined. A prototype is manufactured and experimental verification is conducted. |

| Title: | Electromagnetic Characteristics Comparative Investigation of Five-phase Wide-and-Narrow Stator Poles Axial Flux Switched Reluctance Motors with Different Rotor Poles Number |
| Abstract: | Axial flux switched reluctance motors (AFS-RMs) offer advantages such as a large air-gap surface area, compact structure, and high torque density. This paper proposes a novel five-phase AFSRM structure featuring wide-and-narrow stator poles (NWS-AFSRM) and presents a comparative study of the electromagnetic characteristics of the five-phase NWS-AFSRM with varying rotor pole numbers. Firstly, while maintaining a constant stator pole count, four feasible rotor pole configurations are determined: 20/12, 20/14, 20/16, and 20/18- poles. Subsequently, based on these four pole combinations, their corresponding phase excitation sequences are investigated. Using the finite element analysis (FEA) method, both static and dynamic electromagnetic characteristics are evaluated to analyze the influence of rotor pole number on the motor’s electromagnetic performance. |

| Title: | Research on Switched Reluctance Motor Power Converters in Multi-port Low-carbon Building Microgrid System |
| Abstract: | This paper presents research on a dual-source three-level power converter for a switched reluctance motor (SRM) in a multi-port low-carbon building microgrid system. A front-end circuit is added to the proposed power converter based on the conventional asymmetric half-bridge power converter (AHBPC) for power flow control. It can achieve a three-level power supply by using solar photovoltaic (PV) cells and lead-acid batteries which can be replaced with other power supply modules as needed without affecting system functionality. Three working modes can be achieved according to actual applications by a simple strategy. With the proposed converter, system efficiency and dynamic response can be improved. Working modes of the proposed solution are explained and current paths in the proposed converter are analyzed in detail. Finally, experimental results on a four-phase 8/6 SRM platform are given to confirm the effectiveness of the proposed solution. |

| Title: | Sensorless Position Estimation with Virtual Inductance Vector for Switched Reluctance Machines Considering Asymmetrical Phase Inductance |
| Abstract: | This paper proposes an online sensorless rotor position estimation technique for switched reluctance motors, by which the real-time rotor position is estimated by detecting the virtual inductance vector of the machine. With the proposed technique, rotor position can be estimated accurately, even if the inductance of each phase is asymmetrical. It is achieved by first detecting real-time voltage and real-time current of each phase winding, according to which flux-linkage and inductance of each phase can be thus calculated. With the calclated inductance of each phase, a coordinate system can be established for rotor position estimation. However, since the position estimation accuracy will be reduced by asymmetrical phase inductance, a conversion rule is proposed to convert actual phase inductance to virtual inductance, by which the symmetry of phase inductance can be corrected. Then, according to virtual inductance, a new coordinate system is established for rotor position estimation. In the new coordinate system, position estimation shows high accuracy under both normal condition and asymmetric inductance condition. To conclude, simulation and experimental results are given to verify the effectiveness of the proposed sensorless position estimation technique. |
