项目摘要

A novel topology optimization method has been proposed for the material distribution of electrical motors using the Genetic algorithm combined with the cluster of material and the cleaning procedure. The cluster of several kinds of material is taken into account not only to form the group of iron and the group of air but also to form the group of the r-oriented, x-oriented and y-oriented magnets. Consideration of air, iron and the r-oriented magnet gives a surface permanent magnet type rotor, and consideration of air, iron and the x-oriented and y-oriented magnets gives an interior permanent magnet type rotor. As a result, it was found that permanent magnets are very useful to produce a large torque.In order to develop a motor for electric vehicle without using permanent magnets, a switched reluctance motor with 18 stator slots and 12 rotor slots is designed. It is designed to produce a large average torque more than 400N・m by using the experimental design method coupled with 2-D finite element analysis, where the conventional shape of SRM is chosen as the initial shape to be designed. Eight parameters are chosen as design variables, which define the whole shape of stator teeth and rotor teeth with the assumption of a constant motor volume and a constant air-gap length. An algorithm for an asymmetric bridge converter coupled with finite element method is developed, and then the torque speed characteristics are investigated. The designed SRM has been manufactured.Moreover, a method for generating a music scale from a brushless DC motor with surface permanent magnets has been proposed by introducing a d-axis current with a desired frequency. The proposed method is theoretically verifies by analyzing the vibration emitted from the brushless DC motor. The proposed idea could be applicable to systems emitting a loud acoustic noise from HVs or EVs.

已经提出了一种新型的拓扑优化方法，该方法使用遗传算法与材料簇和清洁程序结合使用了电动机的材料分布。考虑了几种材料的簇，不仅要形成铁和空气组，而且还形成了面向R的，面向X的磁体的组。对空气，铁和面向R的磁体的考虑给出了表面永久磁铁型转子，并考虑空气，铁和面向X的磁体和面向Y的磁体可提供内部永久磁铁型转子。结果，发现永久磁铁对于产生大型扭矩非常有用。为了在不使用永久磁铁的情况下开发电动机，设计了带有18个定子插槽和12个转子插槽的开关不情愿电动机。它旨在通过使用实验设计方法与2-D完成元件分析的实验设计方法产生大于400N ・M的较大扭矩，其中选择了SRM的常规形状作为要设计的初始形状。选择八个参数作为设计变量，该变量定义了定子牙齿和转子牙齿的整体形状，并假设恒定电动机体积和恒定的气隙长度。开发了一种与有限元方法结合的不对称桥转换器的算法，然后研究了扭矩速度特性。此外，通过引入带有所需频率的D轴电流，提出了一种从带有表面永久磁体的无刷直流电动机产生音乐比例的方法。理论上通过分析从无刷直流电动机发出的振动来验证所提出的方法。提出的想法可能适用于从HVS或EVS发出大声的声学噪声的系统。
