【摘要】：近几年,随着永磁材料的发展,永磁电机在民用和工业上应用广泛,关于永磁电机的设计研究也不断发展和深入。永磁体电机按永磁体在转子上位置的不同,可以分为永磁体表贴式(SPM)和永磁体内置式(IPM)电机。内置式永磁同步电机现广泛应用于牵引中,近年不断兴起的新能源电动汽车驱动电机中多采用内置式永磁同步电机。本文主要内容包括内置式永磁电机理论分析、优化设计及样机试验。电机理论分析部分主要包括采用绕组方程分析电机定子磁动势,和电机槽开口对气隙磁导的影响,并给出本文样机模型的定子磁动势和气隙磁导。本文提出了一种基于磁势法的改进后的内置式永磁电机气隙磁场解析模型,该模型可以有效的求得气隙磁场分布。优化设计部分,首先给出了电动汽车驱动电机设计要求,介绍了电机设计过程,并具体进行了电机主要尺寸和细节尺寸的优化设计。最后一部分样机试验包括对样机测试平台结构的介绍,和按照国家标准的电动汽车电机测试项目要求说明,给出了相关测试数据并分析总结。通过对比本文提出的解析模型结果、有限元结果和测试结果,看出该模型可以有效的求得内置式永磁电机气隙磁场分布,用于内置式永磁电机的分析和设计。同时从样机测试数据看出其初步满足了电机设计要求。
[Abstract]:In recent years, with the development of permanent magnet materials, permanent magnet motor has been widely used in civil and industrial fields. It can be divided into permanent magnet surface mount type (SPM) and permanent magnet built-in type (IPM) motor. The built-in permanent magnet synchronous motor is widely used in traction. The built-in permanent magnet synchronous motor (PMSM) is often used in the driving motor of the new energy electric vehicle in recent years. The main content of this paper includes the theoretical analysis of the built-in permanent magnet motor (PMSM). Optimization design and prototype test. The theoretical analysis of the motor mainly includes the use of winding equations to analyze the motor stator magnetoEMF and the influence of the slot opening on the air gap magnetic conductance. The stator magnetodynamic force and air-gap magnetic conductance of the prototype model are given. An improved air-gap magnetic field analytical model based on the magnetic potential method is proposed. This model can effectively obtain the distribution of air-gap magnetic field. In the part of optimization design, the design requirements of electric vehicle driving motor are given, and the design process of the motor is introduced. The final part of the prototype test includes the introduction of the structure of the prototype test platform and the requirements of the electric vehicle motor test project according to the national standards. Through the comparison of the analytical model results, finite element results and test results, it can be seen that the air gap magnetic field distribution of the built-in permanent magnet motor can be effectively obtained by the model. It is used in the analysis and design of the built-in permanent magnet motor. At the same time, it can be seen from the test data of the prototype that it meets the design requirements of the motor.
