First, a new homogenization model is developed with the objective of characterizing the microstructure of SMC. The concepts of insulating layer, pore, and surface roughness structure are introduced. Meanwhile, the thickness of the insulating layer is calculated using the least square, the mass density and volume fraction of the particles are determined using a discrete element method (DEM), and the surface roughness of the particles is characterized using a periodic square waveform. Then, by analyzing the relationship between the microstructural parameters and magnetic properties, analytical expressions are derived to realize the evaluation of the macroscopic permeability and eddy current loss of the SMC. Finally, the SMC-prepared samples are tested by the dc magnetization method and ring sample method, respectively, to verify the reliability of the proposed semi-analytical method by comparing the experimental and evaluation results.","PeriodicalId":13405,"journal":{"name":"IEEE Transactions on Magnetics","volume":"60 11","pages":"1-8"},"PeriodicalIF":2.1,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142517996","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}

Initially, a general formula for determining the interactive force between two arbitrary PMs is derived, resulting in a unified 6-D integral for any magnet pairs. Following this, a computational algorithm utilizing Monte Carlo (M-C) integration for solving the integral is developed. The significance of the presented method is twofold. First, the derived formula and algorithm are unified, enabling the computation of forces between two magnets under general conditions, allowing for arbitrary shapes, magnetizations, and relative locations of the magnets. Second, the approach is applicable to the design synthesis problems, where the geometries of the magnets are to be designed to achieve the prescribed interactive force. Numerical examples are provided to demonstrate the generality and feasibility of the method for magnet-force analysis and synthesis. In addition, the accuracy and efficiency of the proposed approach are discussed and compared with the finite-element-analysis (FEA) simulation in the case studies.","PeriodicalId":13405,"journal":{"name":"IEEE Transactions on Magnetics","volume":"60 11","pages":"1-17"},"PeriodicalIF":2.1,"publicationDate":"2024-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142518156","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}

In the analytical forward model, the test pieces are characterized by the reflection coefficient (RC), which describes the reflection characteristics of test pieces regarding incident electromagnetic (EM) waves and determines the phase of EC signals. The RC is calculated analytically with boundary conditions, which is sophisticated for analyzing complex geometries. In this study, the analytical model of plate and pipe testing using second-order vector potential (SOVP) is investigated. It is found that the numerical RC can be obtained from the source EM field in the air and counterparts in the presence of test pieces. In numerical simulations, the numerical RC is compared with the analytical RC for plate and pipe in a 2-D axisymmetric model. In the 3-D model, the calculated numerical RC corresponds to the dimensions of the measured plate and pipe with defects. In both 2-D and 3-D models, the phase of coil inductance from the numerical RC aligns with the finite-element solutions. It is validated that the RC is a characteristic of test pieces independent of the source field.","PeriodicalId":13405,"journal":{"name":"IEEE Transactions on Magnetics","volume":"60 11","pages":"1-9"},"PeriodicalIF":2.1,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142269535","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}

Hall effect sensors (HESs) measure magnetic fields and provide a simple, inexpensive solution for determining rotor position. In existing systems, the HESs require the addition of PMs outside the motor, or the HESs are sensitive to the magnetic fields produced by the coil, in addition to the magnetic fields from the rotor PMs. However, quasi-Halbach arrays (QHAs), which are used in high-performance PM machines, produce a magnetic field orthogonal to the plane in which the PMs are magnetized. In this article, we investigate placing HESs to measure this orthogonal magnetic field for a simulated axial flux motor. In addition, we investigate this approach in simulation and experiment for a linear system. Both simulation and experimental results show that placing these HESs to measure the orthogonal magnetic fields generated by QHAs allows for the detection of the rotor position using the existing PMs in the machine and without being significantly affected by the magnetic field produced by the stator. In particular, the HESs should be placed orthogonally beyond the QHA and aligned with a stator slot to achieve the best performance. In both the simulated axial flux machine and the experimental linear system, positioning the HES in this manner yielded very good agreement between the flux density waveforms at no load and full load. In addition, the zero crossings of the flux density waveform, which are important for some control algorithms, were less than 1 electrical degree difference between no load and full load.","PeriodicalId":13405,"journal":{"name":"IEEE Transactions on Magnetics","volume":"60 11","pages":"1-7"},"PeriodicalIF":2.1,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142518119","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}
