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.

已经提出了一种新的拓扑优化方法，用于使用遗传算法的材料簇和清洁程序的矩阵Motrical Motors。空气但面向X的磁体，具有X型磁铁型转子。为了使用永久磁铁开发带有18个转子插槽的不情愿的电动机的电动机，设计了带有2-D有限元元件分析的电动机，是SRM的常规形状。使用有限方法的算法，使用有限的桥梁的算法，并使用扭矩特性，则设计了一个一致的运动体积SRM已经制造了。通过分析呈液体发射的无毛线DC TOR来验证D-Axis电流，可以验证支撑的想法。
