进行使用各种磁性材料的电动机的磁特性测量、电动机特性预测和实验评估，以识别在电动机芯中用作磁性材料的各种磁性材料的特征。结果如下：（1）采用非晶金属片的电动机表现出非常高的电动机效率，具有高磁导率和极低的铁损。(2)具有软磁复合铁芯的电机显示出与使用电工钢片的电机相当的效率，尽管磁导率相对较低，并且与低等级电工钢片的铁芯损耗相似。通过增加高频应用和三维结构设计等功能，这种材料有望提供比电工钢板更高的性能。(3)它已被证明，在电机中使用的各种磁性材料的性能可以预测的基础上，其测量的磁性能的高精度。
A magnetic characteristic measurement, a motor characteristic prediction, and an experimental evaluation of motors using various magnetic materials were performed to identify features of various magnetic materials, which are used in a motor core as a magnetic material. The results are as follows: (1) Motor with amorphous metal sheet showed very high motor efficiency, with its high permeability and extremely low core loss. (2) Motor with soft magnetic composite core showed the, comparable efficiency to that of a motor using electrical steel sheet, despite of relatively low permeability and similar core loss to low-grade electrical steel sheet. By adding features such as using in high frequency applications and designing a three-dimensional structure, this material is expected to offer higher performance than that is possible with electrical steel sheets. (3) It has been shown that the performance of the various magnetic materials used in motors can be predicted with a high degree of accuracy based on their measured magnetic properties.
