This article introduces a novel secondary rotary banner UEC structure that meets the high efficiency and reliability requirements for wireless charging of autonomous underwater vehicles (AUVs), while providing the benefits, such as low-temperature rise, easy charging alignment, lightweight design, and strong offset resistance. Based on the strong relationship between the UEC’s temperature rise and the reliability of the underwater WPT system, electromagnetic-thermal-fluid multi-physics coupling simulation models are established for three secondary rotary UECs to compare different secondary-side structures, effectively addressing the challenges of estimating the temperature distribution related to uneven power losses. To further realize accurate calculation of the thermal distribution, the effects of seawater eddies, seawater heat exchange, and the shell are considered. The simulation and experimental results show that the comprehensive performance index of the secondary full-banner UEC is superior, and the temperature rise distribution of the established physical model can be used to accurately predict the actual situation. The maximum error between simulation and practical measurement is 2.45%, which verifies these models, and provides a theoretical basis for improved heat dissipation design of the UEC.","PeriodicalId":13405,"journal":{"name":"IEEE Transactions on Magnetics","volume":"61 4","pages":"1-10"},"PeriodicalIF":2.1,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three-segment magnets with different arc-lengths and different magnetization angles are inset in one stator tooth. For the open-circuit and armature-reaction magnetic fields, according to the governing equations for all divided regions and the boundary condition equations between adjacent subdomains, the complex matrices are constructed and the field distribution can be solved separately. Based on this, the induced electromotive force and electromagnetic torque can be predicted. In addition, the arc-length and the magnetization angle for each magnet segment are optimized. Taking six-slot/14-pole CPFR motors as examples, the optimization results show that the proposed model has better electromagnetic performance than the conventional ones. A prototype motor is manufactured, and the experiments validate the analytical and finite element analysis (FEA) predictions.","PeriodicalId":13405,"journal":{"name":"IEEE Transactions on Magnetics","volume":"61 4","pages":"1-14"},"PeriodicalIF":2.1,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was found that adding an appropriate amount of powder with specific particle sizes can effectively increase sample density, while the permeability variation in HSMCs shows strong dependence on density. The simulation and calculation model considers the random distribution of particles with different grain sizes and the skin effect was established to separate the contributions of eddy current losses and hysteresis losses of different magnetic phases within the HSMCs. The variation of power losses in HSMCs results from the combined effect of magnetic phase mass ratio, material conductivity, relative permeability, hysteresis properties, and particle size distribution. These results provide insights into fabricating high permeability and low-loss power electronic devices for high-frequency applications.","PeriodicalId":13405,"journal":{"name":"IEEE Transactions on Magnetics","volume":"61 4","pages":"1-7"},"PeriodicalIF":2.1,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
