Owing to magnetic saturation, existing methods require nonlinear saturation model and measurements from multiple load/current conditions, and the estimation is relying on the accuracy of saturation model and other machine parameters in the model. Speed harmonic produced by harmonic currents is inductance-dependent, and thus this paper explores the use of magnitude and phase angle of the speed harmonic for accurate inductance estimation. Two estimation models are built based on either the magnitude or phase angle, and the inductances can be from d-axis voltage and the magnitude or phase angle, in which the filter influence in harmonic extraction is considered to ensure the estimation performance. The inductances can be estimated from the measurements under one load condition, which is free of saturation model. Moreover, the inductance estimation is robust to the change of other machine parameters. The proposed approach can effectively improve estimation accuracy especially under the condition with low current magnitude. Experiments and comparisons are conducted on a test PMSM to validate the proposed approach.","PeriodicalId":100229,"journal":{"name":"CES Transactions on Electrical Machines and Systems","volume":"9 1","pages":"91-99"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10946687","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748922","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 2D-Fourier decomposition method is applied to investigate the radial electromagnetic force harmonics (REMFHs). Secondly, Finite element (FE) models are designed for the machine structural analysis. Subsequently, the FE models and modal analysis are explored for different design cases of the analyzed machine. Lastly, vibration and noise behavior are investigated using an FE approach for the machine designs under symmetric and asymmetric assisted poles topologies. The findings indicate an increase in the richness of REMFHs, alongside a decrease in both the fundamental frequency and the lowest nonzero order of REMF, attributed to the presence of asymmetric assisted poles.

Therefore, this paper addresses this issue and proposes potential solutions. Firstly, the paper examines an 8-pole, 48-slot, 6-layer HW TM to highlight the unique characteristics of this winding structure, and explains the uneven distribution of interturn voltage stress and temperature. Subsequently, a high-frequency equivalent circuit model of the HW TM prototype is developed. The error of simulation and experiment is only 5.7 %, which proves the accuracy of the model. Then, an improved HW scheme is proposed to lower the maximum voltage stress by 29.3 %. Furthermore, the temperature distribution of HW TM is analyzed to facilitate a detailed examination of the impact of temperature on insulation PD. Finally, the partial discharge inception voltage (PDIV) of interturn insulation, considering temperature effects, is calculated and verified through experiment. The paper proposes a reliability-oriented design method and process for HW TM. It demonstrates that the reliability-oriented design can achieve PD-free performance in the design stage of HW.","PeriodicalId":100229,"journal":{"name":"CES Transactions on Electrical Machines and Systems","volume":"9 1","pages":"26-35"},"PeriodicalIF":0.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10908521","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748924","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}

To address the temperature misestimation in the LP thermal modelling due to assumptions of concentrated loss input and uniform heat flows, the developed HF-LPTM introduces two compensation thermal resistances for the winding and PM components, which are analytically derived from the multidimensional heat transfer equations and are robust against different load/thermal conditions. As validated by the finite element analysis method and experiments, the conventional LPTMs exhibit significant winding temperature deviations, while the proposed HF-LPTM can accurately predict both the midpoint and average temperatures. The developed HF-LPTM is further used to assess the effectiveness of various cooling techniques under different scenarios, i.e., steady-state thermal states under the rated load condition, and transient temperature profiles under city, freeway, and hybrid (city + freeway) driving cycles. Results indicate that no single cooling technique can maintain both winding and PM temperatures within safety limits. The combination of frame liquid cooling and oil jet cooling for end winding can sufficiently mitigate PMSM thermal stress in EV applications.","PeriodicalId":100229,"journal":{"name":"CES Transactions on Electrical Machines and Systems","volume":"9 1","pages":"1-14"},"PeriodicalIF":0.0,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10857835","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748774","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}

A double-sided AFPM generator with four layers of stator winding is initially designed using a well-known quasi-3D analytical method. Then, the designed machine is simulated using commercial software. It is shown that modification techniques are required to improve the performance of both the torque ripple and the ratio of the third to the fundamental harmonics of the induced voltage. Therefore, a new improvement technique is proposed, in which the layers of the stator winding are shifted relative to each other. While this new technique significantly improves the third harmonic problem, the design still has a high torque ripple and, thus, it is suggested to combine the proposed method with the conventional magnet shifting technique. It is revealed numerically that the resulting combination properly resolves both third harmonic and torque ripple problems. Therefore, this design is considered the main design of the present manuscript. In the end, a prototype of the main design is manufactured and tested. It is shown that the measurement results are in good agreement with those of numerical software.","PeriodicalId":100229,"journal":{"name":"CES Transactions on Electrical Machines and Systems","volume":"8 4","pages":"404-413"},"PeriodicalIF":0.0,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10818788","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142905918","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 novelty of this method is the decomposition of prediction function and the switching optimization algorithm. Based on the decomposition of prediction function, the current increment vector is obtained, which is employed to select the optimal voltage vector and calculate the duty cycle. Then, the computation burden can be reduced and the current tracking performance can be maintained. Additionally, the switching optimization algorithm was proposed to optimize the voltage vector action sequence, which results in lower switching frequency. Hence, this control strategy can not only reduce the computation burden and switching frequency, but also maintain the steady-state and dynamic performance.

However, as motor speed increases, the nonlinearity such as core loss effect will affect the accuracy of machine model and thus the performance of online MTPA control. This paper firstly investigates the performance of the model based MTPA control under different motor speeds through modeling, simulation and experiments, which indicates that the accuracy of MTPA control is greatly reduced especially under high-speeds due to machine nonlinearity. Hence, this paper proposes an efficient nonlinearity compensation model based on polynomial fitting to model and compensate the MTPA error as motor speed increases. Considering both core loss and magnetic saturation effects, the compensation model is a nonlinear polynomial of speed and stator current. To obtain the fitting data, a derivative modeling method is proposed to compute the actual and detected MTPA angles under different speeds, in which the derivative model of torque to current ratio is fitted and the MTPA angle is obtained by setting the derivative model to zero. The proposed compensation model is both computation effective and easy to use for MTPA control, as it computes the compensation term that can be directly combined to other model-based methods. The proposed model is evaluated with experiments and comparisons on a test motor to show the performance improvement.","PeriodicalId":100229,"journal":{"name":"CES Transactions on Electrical Machines and Systems","volume":"8 4","pages":"436-446"},"PeriodicalIF":0.0,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10818786","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142905917","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}
