介绍了一种用于电-涡轮复合系统的双速永磁电动机/发电机的设计，其额定输出功率为10 kW，转速为70 000 r/min。在设计超高速电动机/发电机时，应考虑转子的机械和结构安全性以及电动机高速运行时发生的损耗，以确保安全运行。本文采用有限元分析和结构分析相结合的方法对双速永磁电机进行了优化设计。重点分析了基于套管材料的电磁特性和结构特性。提出了采用碳纤维的永磁电机的优化设计，不仅可以降低电机在极高转速下的涡流损耗，而且可以保证电机的结构安全性。最后，通过实验测试验证了设计方法的正确性和永磁电机样机的有效性。
This paper presents the design of an ultrahigh speed permanent magnet (PM) motor/generator driven at a rated output and speed of 10 kW and 70 000 r/min, respectively, for use in an electric-turbo compounding system. When designing the very-high speed motor/generator, the mechanical and structural safety of the rotor and losses that occur when the motor operates at high speed should be considered for safe operation. In this paper, the optimal design of the ultrahigh speed PM motor is performed with finite element analysis and structural analysis. Especially, the electromagnetic and structural characteristics based on the sleeve material are analyzed. The optimal design for PM motor, using carbon fiber is proposed not only to reduce the eddy-current loss, which prominently occurs at very-high speed, but also to ensure its structural safety. Finally, the validity of the design method and the effectiveness of the fabricated prototype of PM motor is verified through experimental tests.
