我们分析了一种新型机器，通过磁共振耦合传输电能，使电机超轻量化。多相定子绕组和转子绕组之间的磁共振便于在没有磁芯的情况下进行无线功率传输。请注意，磁芯占典型电动机重量的大部分。因此，消除它们大大减少了电机的重量。在这项研究中，我们描述了这种电机的基本设计的特点，并讨论了高频交流损耗的影响。我们分析了电机的设计，使用有限元法磁场分析，以确认它有能力有效地实现高功率密度，并揭示涡流对电机的性能的影响。仿真结果表明，该电机的输出功率可达200 kW，效率大于91%。
We analyze a novel machine that transfers electrical energy via magnetic resonance coupling and makes the motor ultra-lightweight. The magnetic resonance between the multiphase stator and rotor windings facilitates wireless power transfer without magnetic cores. Note that magnetic cores account for most of a typical electric motor’s weight. Thus, eliminating them considerably reduces the weight of the motor. In this study, we describe the characteristics of the basic design of such motors and discuss the effects of high-frequency AC losses. We analyzed the motor’s design using a finite-element method magnetic field analysis to confirm that it has the ability to efficiently achieve high power density and to reveal the influences of the eddy current on the motor’s performance. The simulation results confirm that the proposed motor can output a power of 200 kW with an efficiency of >91%.
