The wound stator core is press fit into a cast iron housing for true and positive alignment as well as efficient heat transfer 盤繞的定子核心被壓鑄進(jìn)鑄鐵外殼內(nèi),不但保證真正的、絕對的校準(zhǔn),還保證高效的熱傳遞。
By the study on the different structure and technics , a new structure of single side tfpm with convolute stator and inner magnet rotor is developed . the stator core is made by convoluted silicon steel tape . the stator manufacture does not need punching 通過對各種電機的結(jié)構(gòu)特點及其加工工藝的分析研究,提出了新型的橫向磁通永磁電機結(jié)構(gòu),定子鐵心采用硅鋼片卷繞結(jié)構(gòu),轉(zhuǎn)子采用內(nèi)置式永磁體結(jié)構(gòu),給出了新結(jié)構(gòu)加工的工藝方法。
Against a prototype which is being produced , its three dimension end region entity model of stator is established , and with the aim of simplifying calculation , the theory of how to simplify entity model is studied , then the theory is made use of , and the end region entity model of stator is simplifi - ed ; meshing characteristics of three dimension entity model and shortcomin - gs of end region entity model of stator are studied , then meshing method of three dimension end region entity model of powerformer stator is studied as well , and the simplified entity model is meshed with this meshed model , the distribution of end region magnetic field of stator is analyzed , and the magnetic field energy and reactance of powerformer end region are calculated and compared with design value because the prototype is being produced , in this paper , stator core , gap and eddy equipment are not taken into consideration , and this has a little influence on the result , but through analysis , the result is proved to be good through the example calculation , it is known that the method of this paper is useful and through theoretic analysis , it is proved that end region 針對一臺生產(chǎn)中的樣機,對其建立了定子端部三維實體模型,而且為了達(dá)到簡化計算的目的,研究了如何將其簡化的理論,并應(yīng)用這些理論對樣機定子端部實體模型進(jìn)行了簡化;研究了三維實體模型的剖分特點和定子端部實體模型存在的缺點,在此基礎(chǔ)之上,研究了對簡化的powerformer定子端部三維實體模型的剖分方法,并且對簡化的實體模型進(jìn)行了剖分。應(yīng)用剖分的三維實體模型,用有限元法分析了powerformer定子端部的磁場分布,計算了端部區(qū)域的磁場儲能,并利用磁場儲能計算了powerformer定子端部漏抗,將計算值與設(shè)計值進(jìn)行了比較、分析。由于樣機處在設(shè)計生產(chǎn)階段,本文暫時沒有考慮定子鐵心、氣隙和渦流器件對端部磁場的影響,這對分析結(jié)果有一定的影響,但是仍然得到較好結(jié)果。
