Study on Different YBCO Bulk Arrangements With a Fan-Shaped Electromagnetic Guideway of HTS Maglev

The application of High Temperature Superconducting (HTS) technology in the maglev field has met a giant improvement in the recent years. With the success in the laboratorial test lines, the scientists started to focus on the research of practical issues on reality applications. Lately, our team devoted ourselves into the study of Electromagnetic Guideway (EMG) for improve the flexibility and the practicability of guideway in an HTS maglev system. In this paper, a fan-shaped EMG was proposed, its basic unit was analyzed through magnetic equivalent circuit method, in order to decide the rated magnetomotive force. Afterward, a prototype was made to verify the design feasibility, the comparison among three arrangements of HTS bulks were carried out with the experiments under different measuring conditions. The levitation and guidance performances of each arrangement were comprehensively discussed as the summary.
