摘要：混合動(dòng)力汽車(HEV)是傳統(tǒng)燃油汽車和純電動(dòng)汽車相結(jié)合的新車型，它采用內(nèi)燃機(jī)和電機(jī)作為動(dòng)力源，具有低污染低油耗的特點(diǎn)，是當(dāng)前解決節(jié)能環(huán)保問題切實(shí)可行的過渡方案。而電機(jī)驅(qū)動(dòng)系統(tǒng)作為混合動(dòng)力汽車中的主要部分，在混合動(dòng)力汽車中起著至關(guān)重要的作用。論文以混合動(dòng)力汽車為研究對象，對混合動(dòng)力汽車的電機(jī)驅(qū)動(dòng)系統(tǒng)進(jìn)行了研究。
本文介紹了混合動(dòng)力汽車的背景和分類，以及對永磁同步發(fā)電機(jī)和串聯(lián)式混合動(dòng)力汽車(SHEV)中輔助功率單元進(jìn)行研究的意義及現(xiàn)狀。分析了永磁同步發(fā)電機(jī)的結(jié)構(gòu)、工作原理,建立數(shù)學(xué)模型。
目前新能源汽車驅(qū)動(dòng)用永磁同步電機(jī)的設(shè)計(jì)方法還不夠成熟，設(shè)計(jì)過程中還存在著許多瓶頸問題。本文運(yùn)用Maxwell 2D以2004款普銳斯IPM電機(jī)為例子研究永磁電機(jī)。本文對豐田prius電機(jī)的設(shè)計(jì)分析方法和主要尺寸公式進(jìn)行詳細(xì)的研究分析，借助RMxprt計(jì)算軟件及Maxwell電磁有限元分析軟件，建立本課題電機(jī)的初始仿真分析模型并對其進(jìn)行相關(guān)電磁參數(shù)優(yōu)化微調(diào)，利用電磁有限元分析軟件對本課題永磁同步電機(jī)的性能進(jìn)行較為全面的仿真分析，結(jié)果表明此兩款電機(jī)具有轉(zhuǎn)矩輸出能力高、轉(zhuǎn)矩波動(dòng)小等一系列優(yōu)點(diǎn)。

The Study of Permanent Magnet Synchronous
Motor Used in Hybrid Electric Vehicle
Abstract：Hybrid Electric Vehicle(HEV) combines the advantages of the traditional fuel vehicle and Pure Electric Vehicle(EV). It uses internal combustion engines and motor as power source. At the same time, the characterics of low pollution and low fuel consumption makes it to be a feasible solution of solving the energy crisis and environmental protection problem. Being a main department of HEV, Motor driving system plays an important part in HEV development. In this paper, HEV motor drive system has been studied.
This paper introduces the background and the classification of HEV. Research Status and Research Significance of PMSG and Auxiliary Power Unit of Series Hybrid Electric Vehicle (SHEV). Structure, Working principle and the establishment of Mathematical Model of PMSG are studied.
Currently, the design methods of permanent magnet synchronous motor for new energy vehicle drive system are not mature enough and there are still many bottlenecks in the design process. in this paper, Study of a Permanent Magnet Motor with MAXWELL 2D:Example of the 2004 Prius IPM Motor. In this paper, the design of the Toyota Prius motor main size formula analysis method and detailed research and analysis, In this paper, the design of the Toyota Prius motor main size formula analysis method and detailed research and analysis, The performance of the permanent magnet synchronous motors with two new non-uniform air gap structure rotors are comprehensively simulated with the help of electromagnetic finite element analysis software. The results show that these two motors have high torque output, small torque ripple, small iron loss，a series of advantages.
