摘要永磁电机采用永磁体建立磁场，使得它能简化结构、降低损耗，并且随着稀土永磁材料发展，在同等体积下的永磁电机能做到输出功率更高，性能更加优异，因而广泛应用于各个电机领域。这也使得永磁电机成为电机学里的研究热点，而本文的研究主要从以下几个层次开展：
首先，详细介绍永磁电机的发展及其相关研究技术，阐述国内外相关领域的研究成果，并建立和提出论文架构及研究目标。
其次，利用传统的经验公式等方法，设计一款12kw的永磁同步电机，得到电机的基本参数，并使用有限元分析软件对电机的基本工作特性曲线进行分析。然后建立电机的二文模型，通过仿真得到基本的输出特性曲线，以确定电机的优化方向。21131
再次，分析定子槽各个参数对电机性能的影响，选取较适合的解对整个电机模型进行参数性优化，比较分析前后方案。
最后，对永磁体尺寸和增加辅助槽等转子结构参数进行分析研究,得到最佳的优化方案。

Title Finite Element Analysis Permanent Magnet Motor
Abstract
Permanent magnet motors use permanent magnets to establish a magnetic field, so that they can simplify the structure, reduce losses. When permanent magnet motors use the rare earth materials，they can do higher output power in the same volume, which is widely applied at various motor areas. This also leads to permanent magnet motors are the most popular subjects in motor learning, my research work is mainly carried out in the following aspects:
Firstly,I introduce the development of permanent magnet motor technology and related research, analyze the domestic and foreign research results on the field, and arrange the research papers framework and objectives.
Secondly, I use the traditional methods such as empirical formula to design a 12kw permanent magnet synchronous motor,and get the basic parameters from it. Then I establish the motor model in a finite element analysis software to analyze its basic operating characteristics curve in order to determine the direction of the motor optimization.
Again, the third paragraph analyzes the impact of each parameter on the performance of motor stator slot in order to choose a suitable solution for motor model parameter optimization.
Finally, the size of the permanent magnet and the auxiliary tank has been tested to analyze the effects of various properties of the motor rotor structure.
Keywords: electromagnetic design permanent magnet synchronous motors finite element analysis optimization of stator slots
