项目摘要

Recently, there are many hopes that high-efficiency and low loss electric devices will allow us to reduce energy consumption and environmental problems. The rapid development of the computer leads the new design tool of electrical machinery and apparatus. The utilization of the magnetic characteristic will develop from the material evaluation guideline to the material recipe. The data volume of vector magnetic characteristic drastically exceeds the conventional magnetic characteristic quantity. It is required that we construct the method for utilizing the vector magnetic property. For example, it will be the practical constitutive equation and modeling which shows vector magnetic characteristic. We newly deduced the magnetic characteristic analysis instead of the magnetic field analysis using vector magnetic hysteretic E & S model.Until now, though many researchers have devised various hysteresis models, the practical result has not been obtained[6]-[7]. The reason is not based on a grasp of the vector magnetic property presented by the relationship between the vector H and the vector B. Furthermore on conventional models, the vector relation between the vector H and the vector B is not considered in the hysteresis. The most difficult phenomenon is to reverse the phase θ_<BH> relation between H and B by the angle in order to make modeling. Then, we should handle engineeringly modeling from the mathematical modeling for such vector magneto-hysteretic representation.In this research, as the magnetic field analysis, we propose the magnetic characteristic analysis, and applied new typed motor by using high grain-oriented electrical steel sheet.

最近，人们希望高效率和低损耗的电力设备能够帮助我们减少能源消耗和环境问题。计算机的迅速发展引领了新的电机及电器设计工具。磁特性的利用将从材料评价指南发展到材料配方。矢量磁特征量的数据量大大超过了常规磁特征量。这就要求我们构建利用矢量磁特性的方法。例如，表现矢量磁特性的实用本构方程和建模。我们新推导了利用矢量磁滞E&S模型来代替磁场分析的磁特性分析。到目前为止，虽然许多研究者设计了各种磁滞模型，但尚未获得实际结果[6]-[7]。原因不是基于对矢量H和矢量B之间的关系所呈现的矢量磁特性的掌握。此外，在传统模型中，在磁滞中没有考虑矢量H和矢量B之间的矢量关系。最困难的现象是通过角度反转H和B之间的相位θ_<BH>关系来进行建模。然后，我们应该从这种矢量磁滞表示的数学建模开始进行工程建模。在本研究中，作为磁场分析，我们提出了磁特性分析，并应用了采用高晶粒取向电工钢板的新型电机。
