This paper clarifies the interdependent relationships among these domains during the machine design process. It reviews key enabling strategies, including machine design based on advanced electromagnetic theory, innovative thermal management techniques, cutting-edge material advancements, and state-of-the-art manufacturing technologies, that collectively enhance the performance and feasibility of high power density machines (HPDMs).

Capacitors, widely used in power converters for filtering, contribute to approximately 30% of failures, predominantly due to electrochemical corrosion leading to capacitance degradation and catastrophic breakdowns. This paper presents a novel capacitor-free solid-state power filter (SSPF) for three-phase inverters, offering a transformative approach to mitigate reliability issues associated with conventional inductor-capacitor (LC) and active output filters (AOFs). Unlike AOFs, which depend on compact LC structures, the SSPF eliminates capacitors entirely, circumventing their inherent failure modes. Leveraging advanced solid-state devices and transformer technology, the SSPF achieves superior filtering performance, enhances system reliability, and significantly reduces component count, utilizing half the metal-oxide-semiconductor field effect transistor (MOSFET) switches required by AOFs. This design not only lowers costs but also improves efficiency. Simulation and experimental results demonstrate the SSPF's capability to deliver a sinusoidal output voltage at the fundamental frequency. These attributes position the SSPF as a robust, cost-effective, and innovative solution for modern power electronics applications.","PeriodicalId":100229,"journal":{"name":"CES Transactions on Electrical Machines and Systems","volume":"9 4","pages":"495-507"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11322815","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145886655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This imbalance leads to significant torsional vibrations and speed fluctuations, which not only compromise passenger comfort but also exert additional mechanical stress on the EVs. Conventional sensorless methods offer speed estimation and control; however, they provide suboptimal performance with sudden load torque disturbances and operational uncertainties, especially at low speeds and across diverse real-world driving cycles. To address these challenges and improve system robustness, this work proposes an advanced sensorless integral sliding mode control (ASISMC) that enhances performance under diverse operating conditions. The proposed ASISMC methodology shows robust performance across a wide speed range, effectively mitigating abrupt load torque disturbances while minimizing the effect of uncertainties within the system dynamics. The approach is experimentally validated for a wide range of speeds and periodic/non-periodic load torque disturbances. Additional validation through the new European driving cycle (NEDC) and urban dynamometer driving schedule (UDDS) demonstrates the method's effectiveness and reliability in real-world driving conditions.","PeriodicalId":100229,"journal":{"name":"CES Transactions on Electrical Machines and Systems","volume":"9 4","pages":"463-472"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11322826","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145886579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the conventional linear permanent magnet synchronous motor (LPMSM) suffers from thrust ripple, which degrades the motor performance. The thrust ripple in LFSPMs is mainly caused by detent force and asymmetric electromagnetic parameters, excluding external disturbances. Moreover, the 12/13 slot-pole LFSPM exhibits unique inductance characteristics, which lead to different effects on thrust ripple. First, the detent force in the LFSPM is analyzed through finite element method (FEM). In addition, new finite element (FE) models are proposed for further analysis of the cogging force in LFSPMs. Second, the unique inductance characteristics of the 12/13 slot-pole LFSPM are investigated, and then the thrust ripple caused by asymmetric electromagnetic parameters is calculated by the virtual displacement method. Third, the mathematical model considering the thrust ripple is established for the LFSPM, which provides a foundation for subsequent research on thrust ripple suppression control strategies.

It aims to provide an effective tool for predicting the distribution of electromagnetic force waves in SynRMs, while exploring the influence of drive modes on their vibration characteristics. The study focuses on a 4-pole, 36-slot 5.5 kW SynRM. Based on the magnetomotive force (MMF)-permeance method, incorporating the special rotor structure and the characteristics of current harmonics under square-wave drive, an air-gap flux distribution function is established. Meanwhile, Maxwell's stress tensor method is adopted to analyze how the air-gap flux density relates to electromagnetic excitation force waves. Subsequently, this analysis is applied to forecast the spatiotemporal distribution features of radial electromagnetic force waves. Finite element simulations are conducted to compute the modal and vibration responses of the SynRM, followed by a comparative analysis of the vibration characteristics under the two drive methods.

To suppress startup disturbances and achieve a control strategy with low computational complexity and high precision, this paper proposes a five-degree-of-freedom hybrid magnetic bearing control strategy based on an improved cascaded reduced-order linear active disturbance rejection controller (CRLADRC). The front-stage reduced-order linear extended state observer (FRLESO) reduces the system's computational complexity, enabling the system to maintain stability during motor startup disturbances. The second-stage reduced-order linear extended state observer (SRLESO) further enhances the system's disturbance estimation accuracy while maintaining low computational complexity. Furthermore, the disturbance rejection and noise suppression capabilities are analyzed in the frequency domain and the stability of the proposed control method is proven using Lyapunov theory. Experimental results indicate that the proposed strategy effectively reduces displacement fluctuations in the hybrid magnetic bearing support system during motor startup, significantly enhancing the system's robustness.","PeriodicalId":100229,"journal":{"name":"CES Transactions on Electrical Machines and Systems","volume":"9 3","pages":"340-351"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11189078","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key of this new AM is to consider armature reaction flux and armature leakage flux, which are closely related to output torque. Firstly, the expressions, including magnetomotive force (MMF) generated by permanent magnets (PMs) and armature windings are derived, and meanwhile slotting effect is considered by planning flux path. In addition, the expression of leakage flux density generated by armature windings are calculated, and flux density equivalence coefficient of tooth is calculated to be 2/3, which is used to solve the problem of uneven saturation of each tooth. Then, based on main flux factor and leakage flux factor proposed, an improved iteration process is proposed, and by this new process, the flux density of each yoke and tooth can be obtained, which is beneficial to obtain more accurate air-gap flux density and flux linkage. Finally, a prototype of 60-pole 54-slot is fabricated, and the performances of the electric machine, such as back electromotive force (EMF) and output torque, are calculated by this new AM and finite element method (FEM). The results of FEM and experimental test show that this new AM is good enough to calculate the performance of PMTM.","PeriodicalId":100229,"journal":{"name":"CES Transactions on Electrical Machines and Systems","volume":"9 3","pages":"289-299"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11189079","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
