摘要：
Traditional power supply methods for rotating mechanisms are found to face problems, including complex structures, limited functionality, and potential safety hazards. To address these problems, a rotary wireless power transfer system with new rail-type coupling structure (RTR-WPT) is proposed in this paper. This system, characterized by safety, reliability, and flexible installation, is designed to provide power to devices mounted on rotating shafts. Firstly, the topological structure of the RTR-WPT system is introduced, and the corresponding circuit model is established. Secondly, MAXWELL is utilized for finite element analysis to design and optimize the rail-type rotary coupler. Finally, an experimental platform for the RTR-WPT system is built and tested. From the experimental results, it is validated that the new rail-type coupler and the design methodology are feasible, and the system can achieve a power transmission of 10.33W with an overall efficiency of 72.1% under rotating conditions.
