为了生产用于电动飞机的超轻电机，我们提出了一种电机，其中电能通过磁共振耦合（MRC）在定子和转子之间转换。该动作引起定子的多相绕组与转子的笼条之间的电磁谐振。电磁共振耦合技术允许电机在没有磁芯的情况下转换能量，从而允许生产超轻电机。在这项研究中，我们提出了一个基于MRC的笼型转子的机器，我们描述了它的工作原理和特性由MRC诱导。建议笼型MRC电机的模型进行磁分析，以评估其在旋转机器中的旋转能量转换，并了解其基本特性。我们的研究结果证实，所提出的笼型无磁芯MRC电机可以转换定子和转子之间的电磁能量，并产生足够的操作转矩。该电机的转差-转矩曲线与感应电机的转差-转矩曲线相似，其转矩随谐振频率增加而增加。
To produce an ultralightweight machine for electric aircrafts, we propose a machine in which electrical energy is converted between the stator and the rotor via magnetic resonance coupling (MRC). This action causes electromagnetic resonance between the multiphase windings of the stator and the cage bars of the rotor. Electromagnetic resonance coupling technology allows electrical machines to convert energy without a magnetic core, thereby allowing the production of ultralightweight machines. In this study, we propose a machine with a cage rotor based on MRC, and we describe its operating principles and characteristics induced by MRC. A model of the proposed cage-type MRC motor is subjected to magnetic analysis to assess its rotational energy conversion in a rotating machine and to understand its essential characteristics. Our results confirm that the proposed cage-type MRC motor without a magnetic core can convert electromagnetic energy between the stator and the rotor and produce sufficient operating torque. This motor operates with a slip-torque curve similar to that of an induction motor, and its torque increases with resonant frequency.
