Yuji Enomoto，Dr. Hirooki Tokoi，Dr. Takao Imagawa Toshifumi Suzuki Takeshi Obata Kenichi Souma，Dr. Eng.概述：随着世界各地对能源效率的日益关注，提高电动机的效率已成为人们感兴趣的主题。在国家法规的推动下，工业电机的效率不断提高，并制定了国际标准来定义效率水平。日立利用非晶合金和日立自己的设计和制造技术，开发出了符合这些效率等级中最严格的IE5的轴向间隙电动机。通过开发降低IE4效率级电机损耗的技术，包括评估电机的内部磁特性和进行精确的分析和设计，日立提出了一种电机设计，大大降低了非晶铁芯的损耗，并成功实现了IE5效率级。
Yuji Enomoto, Dr. Eng. Hirooki Tokoi, Dr. Eng. Takao Imagawa Toshifumi Suzuki Takeshi Obata Kenichi Souma, Dr. Eng. OVERVIEW: Improving the efficiency of electric motors has become a subject of interest amid growing concern about energy efficiency throughout the world. There have been ongoing improvements in the efficiency of industrial motors prompted by national regulations, with international standards having been formulated to define levels of efficiency. Hitachi has developed axial-gap electric motors that comply with the IE5, the most stringent of these efficiency classes, by utilizing amorphous alloys and drawing on Hitachi’s own design and manufacturing technologies. By developing techniques for reducing losses relative to motors in the IE4 efficiency class that involved assessing the motor’s internal magnetic characteristics and performing precise analysis and design, Hitachi came up with a motor design that significantly reduces the losses in the amorphous core and succeeded in achieving the IE5 efficiency class.
