磁鐵心開關 的英文怎麼說
中文拼音 [cítiěxīnkāiguān]
磁鐵心開關
英文
magnetic core switch-
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。1. nizn ferrite was developed for using in mini high frequency dc - dc converters and inductors. we measured and analysed the parameters of the nizn ferrite, which we concern about when designing the dc - dc converter. 2. the low loss sample of nizn ferrite were chosen for design - optimization of the high frequency transformer. based on the relevant theoretical researches, the loss properties of the magnetic core material and winding were analyzed in this thesis
因此，以nizn功率鐵氧體材料為開關電源芯材為基礎，並優化各種開關電源的設計已成為國際上的熱點和技術瓶頸，本論文正是以上述背景為研究目標而開展工作的，主要進行的工作和創新有: 1 .對研製的新型高頻低功耗的功率nizn材料進行參數的測試，並針對dc - dc變換器設計關心的參數對芯材特性進行了分析，選擇在特定頻率下，功耗較小的nizn材料磁芯樣品作為變壓器優化設計的預備磁芯。
