【摘要】：开关磁阻电机以其结构简单、低损耗、易控制等多种优良性能越来越受到人们的广泛关注，其驱动系统很快发展成为一种新型的无极调速系统，在众多领域如电动汽车、航空航天、家用电器等领域的使用越来越普遍。转矩脉动是开关磁阻电机的一个突出缺陷，它一直是学者们研究的重点。开关磁阻电机内部复杂的电磁关系使得传统的电机设计公式不适用于此电机，并且磁路计算相当复杂，因此开关磁阻电机的设计软件显得尤为重要。首先本文简要的阐述了当前开关磁阻电机(SRM)的发展和研究现状，结合电机的结构特性与运行原理，在分析开关磁阻电机几种典型模型的基础上，确定了电机的电磁设计方案。其次深入研究了电机结构参数对转矩脉动的影响，主要参数包括气隙、转子外径、定子外径、绕组匝数、铁心长度及定转子极弧宽度，，并对其部分结构参数进行了优化；之后从优化定转子磁极结构的角度出发，提出了采用定子带极靴的电机结构来抑制转矩脉动的方法，并运用有限元分析软件Ansoft Maxwell对优化后的电机进行全域的有限元分析和电磁计算。最后简要介绍了利用Visual Basic语言进行电机电磁设计的方法，重点研究了Visual Basic与Ansoft Maxwell之间接口技术，参考一些已有的电磁设计公式和经验系数，使用编程语言Visual Basic编制了CAD设计软件，并对开关磁阻电机的CAD输入界面和输出界面进行了详细的阐述，同时通过脚本语言，完成VB与Ansoft Maxwell软件之间的无缝链接，实现了电磁设计工程软件一键式有限元的求解功能。
[Abstract]:Switched reluctance motor (SRM) has attracted more and more attention because of its simple structure, low loss, easy control and so on. The drive system of switched reluctance motor (SRM) has developed rapidly into a new type of electrodeless speed regulation system, such as electric vehicles. Aerospace, home appliances and other areas of use is becoming more and more common. Torque ripple is a prominent defect of switched reluctance motor (SRM). Because of the complex electromagnetic relation of switched reluctance motor, the traditional formula of motor design is not suitable for this motor, and the calculation of magnetic circuit is very complicated, so the design software of switched reluctance motor is very important. Firstly, the development and research status of switched reluctance motor (SRM) are briefly described in this paper. Based on the analysis of several typical models of switched reluctance motor (SRM), the electromagnetic design scheme of SRM is determined by combining the structure characteristics and operation principle of SRM. Secondly, the influence of motor structure parameters on torque ripple is deeply studied. The main parameters include air gap, rotor outer diameter, stator outer diameter, winding turns, iron core length and stator pole arc width, and some of its structural parameters are optimized. Then from the point of view of optimizing the stator and rotor magnetic pole structure, a method of restraining torque ripple by using the motor structure with stator pole boots is put forward. The finite element analysis and electromagnetic calculation of the optimized motor are carried out by using the finite element analysis software Ansoft Maxwell. In the end, the paper briefly introduces the method of electromagnetism design of motor using Visual Basic language, and focuses on the interface technology between Visual Basic and Ansoft Maxwell, referring to some existing electromagnetic design formulas and empirical coefficients. The CAD design software is programmed with the programming language Visual Basic, and the CAD input interface and output interface of switched reluctance motor are described in detail. At the same time, the seamless link between VB and Ansoft Maxwell software is completed by script language. The function of solving one-key finite element of electromagnetic design engineering software is realized.
