| Summary: | 碩士 === 國立成功大學 === 電機工程學系 === 106 === In this thesis, an improved type of the contactless rotating power transfer system with active vertical maglev structure for rotating applications in the medical field is proposed. The body shape of the rotating equipment is designed as a cavity in which to place the experimental unit, and the rotating equipment is constructed to work in an isolated place. The magnetic field finite-element-method simulation software is used to analyze the different co-constructions combined with the maglev DC coils and the inductive power transfer AC coils which are proposed in this thesis. According to the analysis, the planar toroidal magnetic coupling structure is chosen. To improve the power transfer efficiency, the S-P resonant topology is chosen. Moreover, in order to verify the feasibility of the power transmission in the process of rotation, a permanent magnet synchronous motor structure is integrated. The horizontally stable structure is integrated by two permanent maglev layers in this thesis. Based on the experimental results, the maximum output power received in load of the rotary machinery is 139 W with conversion efficiency of 66.17%. In addition, the maximum conversion efficiency has reached about 72.02% with 109 W output power.
