针对混合动力汽车动力分配装置的候选方案之一--磁齿轮传动双转子电动机（MGDRM），提出了一种实用的设计指南。首次采用轮辐式永磁转子和简化的互补结构，形成了一种新型MGDRM，它具有较小的漏磁，较低的成本，和较小的转矩涟漪。在此基础上，提出了一种考虑外转子高度的有限元辅助关键尺寸设计技术，其目标是在给定电机体积下产生最大转矩。该方法还考虑了岩心饱和度。此外，为了提高互补MGDRM的可制造性，提出了一种独特的技术来实现具有简单部件的双转子结构。设计并制造了16 kW样机。在混合动力试验台上进行了试验，验证了所提出的设计和制造技术。
This paper presents a practical design guide for the magnetic-geared dual-rotor motor (MGDRM), which is one of the candidates of the power split device in hybrid electric vehicles. The spoke-type permanent magnet rotor and simplified complementary structure are first used to form a new MGDRM, which exhibits less flux leakage, less cost, and less torque ripple. Based on this structure, an FEA aided key dimensions design technique, considering the height of the outer rotor, is developed with the goal of generating maximum torque for a given motor volume. The method also takes the core saturation into consideration. Moreover, to enhance the manufacturability of the complimentary MGDRM, a unique technique is proposed to implement the dual rotor structure with simple components. A prototype of 16 kW is designed and manufactured. Experiments are carried out on a hybrid powertrain test bench, verifying the proposed design and manufacture technique.
