【摘要】:本文深入分析與研究了雙凸極輪轂電機(Doubly Salient Hub Motors,簡稱DSHM)的運行原理,建立了數(shù)學(xué)模型。 根據(jù)電動汽車對驅(qū)動電機的性能要求,結(jié)合傳統(tǒng)電機設(shè)計的理論知識,初步確定DSHM的結(jié)構(gòu)和尺寸。給出尺寸確定的計算流程并編制相應(yīng)的計算機程序,形成“尺寸確定”功能模塊,并應(yīng)用該程序初步確定12/8極DSHM的結(jié)構(gòu)尺寸,得出初始方案。 建立了DSHM二維有限元數(shù)學(xué)模型,設(shè)計適合于DSHM的有限元分析的計算流程。又采用軸向分段,二維磁場有限元計算的方法,設(shè)計出轉(zhuǎn)子斜槽型DSHM的有限元計算流程。利用C++算法語言在VC++的MFC平臺上,按照上述設(shè)計流程,編制了適用于DSHM的電機磁場有限元分析軟件,并對該自主研發(fā)的軟件的功能(尺寸確定、有限元前處理、有限元計算和有限元后處理)進行詳細(xì)的說明。 利用上述分析軟件,對DSHM進行了磁場有限元計算,核算其運行性能。通過與設(shè)計要求對比,并對初始方案的某些數(shù)據(jù)進行了反復(fù)修改,,得出最終方案。然后又深入分析了直槽轉(zhuǎn)子時電機的靜態(tài)特性,包括空載靜態(tài)特性如磁力線分布、繞組磁鏈特性和定位力矩特性等。為了降低轉(zhuǎn)子直槽時的轉(zhuǎn)矩脈動和定位力矩,為此,又計算和分析了轉(zhuǎn)子斜槽型的DSHM在不同轉(zhuǎn)子傾斜角度下的電磁參數(shù),得出其靜態(tài)特性。分析表明斜槽轉(zhuǎn)子能有效地減小定位力矩,改善繞組電動勢波形,降低轉(zhuǎn)矩的脈動。
[Abstract]:In this paper, the operation principle of double salient hub motor Doubly Salient Hub Motors, (DSHM) is deeply analyzed and studied, and the mathematical model is established. According to the performance requirement of electric vehicle driving motor and the theoretical knowledge of traditional motor design, the structure and size of DSHM are preliminarily determined. The calculation flow of dimension determination is given and the corresponding computer program is compiled to form the function module of "size determination". The structural dimensions of 12 / 8 pole DSHM are preliminarily determined by the program, and the initial scheme is obtained. The DSHM two-dimensional finite element mathematical model is established and the flow chart of finite element analysis suitable for DSHM is designed. The finite element calculation flow of rotor slant groove DSHM is designed by using axial segment and two-dimensional magnetic field finite element method. Using C algorithm language on VC MFC platform, according to the above design flow, a finite element analysis software for motor magnetic field is developed for DSHM, and the function of the software (dimension determination, finite element preprocessing) is given. Finite element calculation and finite element post-processing are described in detail. Using the above analysis software, the magnetic field finite element calculation of DSHM is carried out, and its running performance is calculated. By comparing with the design requirements and modifying some data of the initial scheme repeatedly, the final scheme is obtained. Then the static characteristics of the rotor with straight grooves are analyzed, including the static characteristics of no-load, such as the distribution of magnetic field lines, the characteristics of winding flux chains and the characteristics of positioning torque, etc. In order to reduce the torque ripple and positioning torque of the rotor with straight grooves, the electromagnetic parameters of the skewed rotor DSHM are calculated and analyzed, and its static characteristics are obtained. The analysis shows that the skew slot rotor can effectively reduce the positioning torque, improve the winding EMF waveform, and reduce the torque ripple.
