电动飞机的实际实现需要一种超轻型电动机。在这项研究中，我们提出了一种新的电机，可以转换能量，没有磁芯使用磁共振耦合（MRC）。MRC涉及使用两个分离的线圈连接到谐振电容器，以通过线圈之间的大空气间隙传输大量能量。在这项研究中，新的MRC机进行评估，使用理论模型来验证电机的可行性，并确定不同的气隙长度的基本频率特性。磁场分析和实验结果证实了MRC电机在不使用磁芯的情况下也能产生谐振转矩，并且受到气隙长度的影响。
An ultra-lightweight motor is required for the practical realization of electric aircraft. In this study, we propose a novel motor that can convert energy without magnetic cores using magnetic-resonance coupling (MRC). MRC involves the use of two detached coils connected to a resonant capacitor to transfer enormous amounts of energy through a large air gap between the coils. In this study, the novel MRC machine is evaluated using a theoretical model to verify the feasibility of the motor and to determine the basic frequency characteristics for different air-gap lengths. The magnetic field analysis and experimental results confirmed that the MRC machine can produce torque due to resonance without the use of a magnetic core and is affected by the air-gap length.
