Research and development of Non Rare-Earth Permanent Magnet Design-Oriented Electric Machines for Electric Vehicles

本文介绍了驱动性能的无刷同步电机与绕场励磁使用SMC核心混合动力汽车的应用。建议的机器没有电刷或滑环，稀土磁铁，只采用绕线励磁。介绍了该机床的结构和基本工作原理。设计目标是电机最大功率大于123 kW，最大功率密度大于3.5kW/kg。基于三维有限元分析对所设计的机床进行了性能分析，结果表明该机床满足设计要求。最后，一些实验结果，使用测试缩小机器进行演示。

This paper presents drive performance possibilities of brushless synchronous machine with wound-field excitation using SMC core for HEV applications. The proposed machines have no brush or slip ring, rare-earth magnet and employs only wound-field excitation. The structures and the basic working principles for the machine are overviewed. The design target is the motor with maximum power more than 123kW and maximum power density more than 3.5kW/kg. The performance analyses of the designed machines based on 3D-FEA show that the machine meet the target requirements. Finally, some experimental results using a tested down scale machine are demonstrated.
