pole core-
Ferrite cores - guide on the limits of surface irregularities - part 3 : etd - cores and e - cores
鐵氧體磁心表面缺陷極限導則第3部分: etd和e形磁心The magnetic flux can flow inside the core with extreme low reluctance
使磁通以極小的阻力在鐵心中流通。Since iron hearts of a very similar role to iron core magnetic - fluid changes will enable the inductance with the electrical frequency change, and therefore affect the dynamics of the electrical performance
5 .由於爪極鐵心中的渦流作用引起鐵心磁導的變化，也就使電機的電感隨頻率而變化，因此影響電機的動態性能。Analysis for magnetic field of srm is very complicated since the flux waveforms in different parts of the motor vary with motor phase, stator pole and rotor number, also with the winding connections, etc, which results in the srm losses, especially iron loss calculation difficult. the temperature analysis due to the losses has become a study hot spot
Sr電機鐵心的磁通波形不僅與電機的相數有關，還與定、轉子齒極數、定子繞組連接方式等密切相關，從而使得sr電機磁場分析很復雜，復雜的磁通密度波形導致電機損耗特別是鐵損的計算非常困難。電機的損耗又會引起電機的溫升，因此高性能的sr電機的熱分析也成為目前的研究熱點。As a new kind of motor, switched reluctance motor ( srm ) has a doubly salient structure, and its windings are only mounted on the stators. these characteristics bring srm lots of virtues : solid structure, high reliability and efficiency, good fault - tolerance, low cost etc. switched reluctance driver ( srd ) combined srm with modern power electronic technology and control technology
開關磁阻電機（ srm ）作為調速電動機的新品種，採用定、轉子雙凸極鐵心結構，並且只在定子上裝有集中繞組，轉子上無繞組或永磁體，具有結構簡單堅固、運行可靠、效率高、功率變換簡單、容錯性好和成本低等優點。With summarizing and describing systematically the fundamental principles and research developments of electromagnetic field in the motor, finite element analyses ( fea ) of electromagnetic field of engineering, the switched reluctance motor ( srm ), and iron losses of motor cores, taking the common four - phase, 8 / 6 - pole srm as the object of study, this paper analyses, calculates, and then simulates the electromagnetic field in the srm using 2d finite element method, and obtains the - i - characteristics as the magnetization curve of the srm with the data derived from the results of fea
本文在系統地總結和描述電機內的電磁場、工程電磁場有限元分析、開關磁阻電機（簡稱sr電機）以及電機鐵心損耗基本理論和研究進展動態的基礎上，以常見的四相8 6極電機作為分析對象，進行sr電機磁場二維有限元分析與計算，對電機內磁場進行了模擬，並通過有限元計算所得有關數據獲得- i -形式的sr電機磁化曲線。Ferrite cores - guide on the limits of surface irregularities - part 2 : rm - cores
