Abstract

This study presents the development of a small electric vehicle (EV) traction drive motor using Fe-based amorphous laminated cores that can be mass produced. The following innovative technologies are developed to realize the amorphous laminated core: (1) production technology for thicker amorphous alloy foils to reduce the number of machining operations and (2) punching press technology for amorphous alloy foils that improves the usability of the tool life and maintains quality. The interior permanent magnet synchronous motor (IPMSM) using the amorphous laminated core is designed to be compatible with a 4.5-kW-class small EV traction drive with high efficiency while satisfying the required torque characteristics. A prototype of the designed IPMSM was manufactured and evaluated. The test machine achieves a maximum efficiency of 98.7% and a wide range of efficiencies exceeding 97%. Additionally, the prototype motor exhibit improved efficiency in all operating points compared with a prototype manufactured using an electrical steel sheet.

使用可量产的非晶层压磁芯的小型电动汽车牵引驱动电机

本研究介绍了使用可大规模生产的铁基非晶层叠磁芯开发小型电动汽车（EV）牵引驱动电机的情况。为实现非晶叠层铁芯，开发了以下创新技术：（1）较厚非晶合金箔的生产技术，以减少加工操作次数；（2）非晶合金箔的冲压技术，以提高工具寿命的可用性并保持质量。采用非晶叠片铁芯的内部永磁同步电机（IPMSM）可与 4.5 千瓦级小型电动汽车牵引驱动装置兼容，在满足所需的扭矩特性的同时具有高效率。对所设计的 IPMSM 原型进行了制造和评估。测试机的最高效率达到 98.7%，效率范围超过 97%。此外，与使用电工钢板制造的原型相比，原型电机在所有工作点的效率都有所提高。
