Linear induction motor is an important kind of machines which have some merits such as simple structure, low cost, durability, convenience for maintenance etc. the subject of this thesis is to study a big circular ring linear induction motor, and the major works in this thesis are summarized as follows : ( 1 ) considering the effects of the finite length of primary core, one - dimension analytical solution for the air gap field is cited in this paper. based on it, the single layer winding magnetic field is studied. considering whole - pitched and short - pitched winding configuration with odd poles and half - fulled slots in both ends, the double - layer winding magnetic field is analyzed, respectively
本文對大圓環直線感應電機進行了深入細致研究，內容包括： （ 1 ）本文採用有限長行波面電流作用於有限長鐵芯上的模型，引用了氣隙磁場一維解，研究了單層繞組磁場，奇數極半填槽雙層繞組在採用整距和短距時磁場的分析、比較，簡單介紹了二維解； （ 2 ）用有限元軟體ansoft對大圓環直線感應電機空載氣隙磁場進行了靜態分析，並分析了結果； （ 3 ）用軟體進行了額定電壓下的瞬態分析，得到了轉矩，位移，轉速隨時間變化曲線圖，利用單極性霍爾元件測定轉速並與軟體計算結果進行了比較，採用等效電路法計算了堵轉時的最大電磁力並做實驗進行了驗證，由實驗測得了三相電流波形，並與計算結果進行了比較，對其不對稱性進行了定性分析。A precision force banacing accelerometer for ineration navigation application is developed. the resolution, low - sensitivity threshold and high thermal stability are considered as design parameters. in order to guarantee a low - sensitivity threshold while maintaining robustness against shock, push - pull type long flexures are used in this paper. to improve thermal stability, this paper discusses the use of electromagnets as a magnetic fied source. the silicon pendulum assembly and modified inducance type pick - up is also developed to reduce assembling procedure. the measure range of accelerometer is 0 - 70g
加速度計的解析度、靈敏度閾值和高的熱穩定性是設計時主要考慮的參數。本論文中使用推?挽式長撓性結構來保證低靈敏度閾值，同時保證抗振魯棒性。為了提高熱穩定性，本文中討論了利用永久磁鐵作為磁場源；微加工技術被引入擺組件的結構設計和利用力矩線圈作為激勵線圈來簡化電感式的檢測裝置。For example, when magnetic material being pressed, magnetic domain, direction and strength of spontaneous magnetization will vary. this phenomenon is called effect of pressing magnet. whichever rearrangement of magnetic domain or direction change of spontaneous magnetization will induces extra shape change of material
如對鐵磁材料施加應力時，往往會導致磁疇、自發磁化方向和強度發生變化，這一現象稱之為壓磁效應，由於得益於壓磁效應的作用，不論是磁疇重新排列還是自發磁化方向發生變化都會引起材料額外的形變，因此在一定應力的作用下鐵磁材料能產生非彈性變形。Second, while china ' s low - cost labor pool has provided an extremely effective magnet for global manufacturing, the country ' s competitive advantage won ' t last forever
第二，雖然中國低廉的勞動力市場像一塊強力磁鐵對全球製造業產生巨大吸引，但中國的競爭優勢不會永久保持Company development and production of products mainly include : industrial control and monitoring, dc converter, exchange converter, permanent magnet motor, power generation electronic control system, various industrial control module, railway traction systems and urban transport systems
