Abstract

In response to the issue of providing a wireless power supply to the magnetic focusing rotor torque and torsion sensors on the rotating shaft systems, loose-coupled transformers (LCTs) are difficult to disassemble and install due to their large size. In addition, their large mass has a significant impact on the dynamic balance of the shaft system. Consequently, in this paper, a structural design of an flexible printed circuit (FPC)-stacked receiving coil is proposed, with its mathematical model, physical model, and simulation model established. The optimal structure is obtained by simulating the coil-induced voltage under different structural parameters through COMSOL electromagnetic simulation. Through modal simulation analysis of the rotor in ANSYS, it is found that the FPC-stacked receiving coil has less impact on the dynamic balance of the rotating shaft system.

用于向旋转轴传感器无线传输电力的 FPC 接收线圈
针对为旋转轴系统上的磁聚焦转子扭矩和扭转传感器提供无线供电的问题,松耦合变压器(LCT)因其体积庞大而难以拆卸和安装。此外,它们的大质量对轴系统的动态平衡也有很大影响。因此,本文提出了一种柔性印刷电路(FPC)叠层接收线圈的结构设计,并建立了其数学模型、物理模型和仿真模型。通过 COMSOL 电磁仿真模拟不同结构参数下的线圈感应电压,获得最优结构。通过在 ANSYS 中对转子进行模态仿真分析,发现 FPC 叠层接收线圈对旋转轴系统的动平衡影响较小。
