Although MP rotating machines have been extensively studied in the literature, little research has been carried out on MP linear electrical machines and their application in the transportation sector. In this context, this article proposes a highly accurate and computationally efficient analytical model of MP single-sided linear induction motors (SLIMs) validated through comparison with finite-element analysis (FEA) simulations over a large interval of operational speeds (i.e., <inline-formula> <tex-math>$0~{mathrm { m}} cdot {mathrm { s}}^{-1} leq v_{m} lt 150~{mathrm { m}} cdot {mathrm { s}}^{-1}$ </tex-math></inline-formula>). The proposed model, obtained by extending the one published in previous works by the authors, is used to analyze the performance of different MP SLIMs in terms of forces (i.e., thrust and normal force) and efficiency. A comparison with a three-phase SLIM is presented too. Furthermore, the effect of an iron appendix installed at the rear of the motor, which has been shown to increase the levitation force of SLIMs at high speed, has been added to the presented analysis. The results of the analysis demonstrate that an MP supply greatly affects the forces developed by the SLIMs and represents a solution to integrate propulsion and levitation (PL) functionalities into a single LIM for magnetic levitation (maglev) vehicles.","PeriodicalId":13405,"journal":{"name":"IEEE Transactions on Magnetics","volume":"61 9","pages":"1-10"},"PeriodicalIF":1.9,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144909034","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}

The precise and high-quality fabrication of MTJ devices in laboratory settings is crucial for driving advancements in MTJ research. This study introduces a high-precision, cost-effective, and efficient fabrication method for nanoscale MTJ devices by integrating metal hard mask etching (etch-back) with conventional lithography techniques. This approach enables the production of devices with nanopillar dimensions as small as 100 nm, achieving a remarkable 100% yield. The fabricated devices demonstrate outstanding performance metrics, including a resistance–area (RA) product of <inline-formula> <tex-math>$23~Omega cdot mu $ </tex-math></inline-formula>m2, a tunneling magnetoresistance (TMR) ratio of 110%, reliable spin-transfer torque (STT)-induced switching behavior, and a robust spin-torque diode effect.

This approach enables the inclusion of effects such as mechanical stress, magnetostriction, material anisotropy, and crystallographic texture. By integrating the anhysteretic model into the EB framework, it becomes possible to account for dissipative effects (in our case, domain wall pinning) while utilizing detailed material information. To solve the EB model in conjunction with the SMSM, two approaches are pursued: a numerical optimization of a free energy functional and an explicit approximate variant, known as the vector play model (VPM). Both methods are compared in terms of computational performance, and the differences in results are demonstrated through the simulation of the cross section of an electric machine. Furthermore, the local as well as global behavior is investigated. It is shown that in an electrical machine configuration, the VPM provides a very satisfactory approximation to both local and global responses, together with a reduced computation time compared to the EB model. In the provided application case, it is shown that a shrink-fitting operation can lead to a 30% increase in the overall hysteresis losses.","PeriodicalId":13405,"journal":{"name":"IEEE Transactions on Magnetics","volume":"61 8","pages":"1-14"},"PeriodicalIF":2.1,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11062564","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144716345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
