摘要 當前社會科技飛速發(fā)展，人民的生活水平日益提高的同時，也帶來了資源短缺、環(huán)境污染等負面問題，在這樣的大背景下，混合動力汽車（HEV）作為傳統(tǒng)燃油汽車與純電動汽車的過渡車型，成為當前世界各國研究的熱點。自1997年日本豐田集團的普銳斯混合動力車型在世界市場上量產化以來，它已越來越被大眾所熟知，早已不是罕見的新品。但是，混合動力依舊有很多關鍵性的技術需要去研究，各國也對其相當重視，投入了大量的財力物力。相信日后，混合動力汽車必將有良好的市場前景。
本文以混合動力汽車為背景，首先對混合動力汽車進行了簡要的介紹，包括混合動力汽車的背景發(fā)展、通用概念、結構分類以及各自的特點。
其次，對當前熱點研究的永磁電機特別是正弦波永磁電機進行了理論上的分析與模型介紹，對永磁電機的轉子結構進行簡要分析，提出采用內嵌式永磁電機的概念。同時，對永磁電機的矢量控制進行簡單介紹，為后期研究做出鋪墊。
最后，對適用于混合動力系統(tǒng)中的內嵌式永磁電機進行分析研究，以豐田普銳斯電機模型為模版，利用Ansoft/Maxwell軟件，在Maxwell平臺上建立普銳斯電機模型，通過有限元分析的方法，對其進行靜態(tài)、動態(tài)磁場下一系列的仿真分析，得到在電磁場作用下轉矩、磁通密度、磁鏈、反電動勢等數(shù)據(jù)與波形，進行相應的參數(shù)分析，從而為后續(xù)深入的研究奠定基礎。

Research on Interior Permanent Magnet Motor for Hybrid Electric Vehicles
Abstract In current social, rapid development of technology, increasing people's living standards, but also brought negative issues that is shortage of resources and environmental pollution. In this context, hybrid electric vehicles (HEV) become a hot current study around the world as a transition models between traditional fuel vehicles and pure electric vehicles. Since the Toyota Prius hybrid electric vehicles group in the world market mass production in the 1997, it has become increasingly well known by the public, no longer a rare new self. But there still are a lot of key of hybrid technology needs to study, many countries also think it important and put a lot of financial and material resources. I believe in the future, hybrid cars will surely have a good market prospect.
In this paper, in the background of hybrid cars, Firstly,,we have a brief presentation about hybrid car, including the background of the development of hybrid electric vehicles, general concepts ,structure classification and their characteristics.
Secondly, the current focus of research on permanent magnet motors especially sine wave permanent magnet motor were introduced by some theoretical analysis.We give a brief analysis of rotor structure model of permanent magnet motor and put forward the concept of using interior permanent magnet motor. A brief introduction about Vector control for permanent magnet motor paves the way for the latter to make a further study.
Finally,there is an analysis about the interior permanent magnet that is fit for hybrid system.We use the Toyota Prius motor model as a template to build Prius motor model in maxwell platform by using Ansoft / Maxwell software.After the finite element analysis,there is some simulation analysis solution in static and dynamic magnetic field .We get the torque, flux density, flux, and the back-EMF waveform in the electromagnetic field and the corresponding parameter analysis lays the foundation for the subsequent in-depth study .
