The subject of this thesis is to study ironless moving coil linear permanent magnet synchronous motor and the major works in this thesis are summarized as follows : 1 ) two analytical formulas are derived by concentrated current method and distributed current method to determine the magnetic field due to pm, based on the current model of pm. besides, two method ( magnetic charge method and solution by laplace equation method ) are also introduced with comparing their advantages and disadvantages. then the effects of the motor parameters on the flux distribution are discussed
本文對空芯動圈式直線同步電動機進行了深入細致的研究，內容包括： （ 1 ）採用電流模型推導出兩種計算永磁磁極二維氣隙磁場的解析公式（集中電流法、分佈電流法） ，同時介紹了兩種永磁電機氣隙磁場計算方法（磁荷法，直接求解拉氏方程法） ，分析各種方法的優缺點，討論電機參數對氣隙磁密的影響； （ 2 ）介紹了單層同心繞組的布置方式，根據安培定律推導出空芯動圈式直線永磁同步電動機的靜推力計算公式，分析靜態力?位移特性； （ 3 ）建立空芯動圈式直線永磁同步電動機動態模擬模型，模擬不同驅動方式下電動機起動、穩態運行時電磁力、速度、位移的變化情況。The kalv ltd. is now area - service 100 % private company, owning the armed - guarded locked area in budapest, immediately next to one of the main transport line, easy outgoing connections to the highway - ring of budapest
Kalv有限公司現為一個提供區域服務的100 %私有公司，位於布達佩斯的武裝保護封閉區，僅鄰運輸干線，且與布達佩斯的繞城高速公路的連接極為方便。But in fact, there are many windings on each leg of a balance transformer, and the winding impedance relationships that the balance condition requires are strict, so it is difficult to design and make such transformers. if adopting the connection scheme of dual windings, the windings on single leg will increase almost doubly. it is more difficult to satisfy the balance condition and probably it will confront conflict when arranging these windings, so parameters of various phases can not be balanced
事實上由於平衡變壓器單柱繞組數目較多，若採用雙重接線方案，則單柱繞組數目增加近一倍，滿足平衡條件十分困難，甚至使得繞組在空間上的布置產生矛盾，無法達到各相參數平衡的要求，而「四相四心柱「結構的三相變四相電力變壓器較好的解決了這一難題。
