摘要
利用磁力线在三维空间中闭合且不相交的特性,提出一种呈近似凹面镜分布的电磁线圈多磁极阵列,来实现磁场聚集。利用在协磁极产生协磁场作用下,主磁极中心磁场在一定范围内呈现近似均衡磁场的管状分布,且能延长磁场均衡范围的特性,实现无线电能传输系统的能量传输距离的提升。最后,通过仿真验证了理论分析的正确性。
With magnetic force lines in 3D space closed and disjoint characteristics,an approximately concave mirrors the distribution of the electromagnetic coil of the multi pole array to realize field aggregation is proposed.The magnetic field of the main magnetic field is in a certain range of the magnetic field,and the magnetic field can be extended to the transmission system.Finally the correctness of theoretical analysis is verified by simulation.
