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.
