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

最近，有很多希望，高效率和低损耗的电子设备将使我们减少能源消耗和环境问题。计算机的迅速发展催生了新的机电设备设计工具。磁性的利用将从材料评价指南发展到材料配方。矢量磁特性的数据量大大超过了传统的磁特性量。这就要求我们构造利用矢量磁性质的方法。例如，它将是实用的本构方程和建模，以显示矢量磁特性。本文用矢量磁滞e&s模型代替磁场分析，推导出磁特性分析方法。迄今为止，虽然许多研究者设计了各种迟滞模型，但尚未获得实际结果[6]-[7]。其原因不是基于对矢量H和矢量B之间的关系所表示的矢量磁性的把握，而且在常规模型中，矢量H和矢量B之间的矢量关系在迟滞中没有考虑。最难的现象是将H和B之间的相位θ_<BH>关系通过角度反转来进行建模。然后，我们应该从数学建模的角度对这种矢量磁滞表示进行工程建模。在本研究中，作为磁场分析，我们提出了磁特性分析，并采用高晶粒取向电工钢板应用于新型电机。

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.
