Development of High Efficiency Motor with High Grain-Oriented Electrical Steel Sheet by Two-Dimensional Vector Magnetic Property

近年来，人们对高效率和低损耗的电气设备寄予厚望，希望它们能帮助我们减少能源消耗和环境问题。计算机的迅速发展，为电机电器的设计带来了新的工具。磁特性的利用将从材料评价指标向材料配方发展。矢量磁特性的数据量大大超过了常规磁特性量。这就要求我们建立利用矢量磁特性的方法。例如，它将是实用的本构方程和建模，表现出矢量磁特性。我们新推导出的磁特性分析代替了矢量磁滞E & S模型的磁场分析，迄今为止，虽然许多研究者设计了各种磁滞模型，但还没有得到实际的结果[6]-[7]。其原因不是基于对由矢量H和矢量B之间的关系所呈现的矢量磁特性的把握。此外，在传统模型中，在滞后中没有考虑矢量H和矢量B之间的矢量关系。最困难的现象是将H和B之间的相位θ_关系<BH>颠倒角度，以便进行建模。在本研究中，作为磁场分析，我们提出了磁特性分析，并应用于高晶粒取向电工钢片的新型电机。

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.
