In this article, a new double-rotor multiwinding machine (DRMWM) that utilizes the flux modulation principle is proposed for propulsion system of hybrid electric aircrafts (HEAs). First, the operation principle of DRMWMs and the corresponding HEA propulsion configuration are introduced, where different operation modes of two rotors and three sets of windings of DRMWMs to cope with various flight tasks of HEAs are elucidated. Then, an improved subdomain method is utilized to solve the magnetic field distribution of DRMWMs with the consideration of saturation effect of soft-magnetic material (SMM). Finally, a prototype is manufactured to verify the effectiveness of the proposed improved subdomain method in predicting the electromagnetic performances of DRMWMs. The experiment shows that the DRMWM is a good candidate to be applied in HEA with different operation modes.

混合动力飞机推进用双转子多绕线机的解析建模

在本文中，针对混合动力电动飞机 (HEA) 的推进系统提出了一种利用磁通调制原理的新型双转子多绕组电机 (DRMWM)。首先介绍了DRMWMs的工作原理和相应的HEA推进配置，阐述了DRMWMs的两个旋翼和三组绕组的不同工作模式，以应对HEA的各种飞行任务。然后，考虑软磁材料（SMM）的饱和效应，采用改进的子域方法求解DRMWM的磁场分布。最后，制造了一个原型来验证所提出的改进子域方法在预测 DRMWM 的电磁性能方面的有效性。
