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
