Résumé

The integration of superconductors in rotating electrical machines is a major trend in the advancement of technology. The advantages of High Temperature Superconductor (HTS) made them an excellent choice over low temperature superconductors. Due to the ceramic nature of second-generation (2G) HTS, sharp bending in HTS tape causes superconducting property losses. Thus, making small superconducting machines using HTS tape is not encouraged. This research focuses on the design, fabrication and testing of pole coil for partially superconducting synchronous generator developed by modifying the existing available induction motor of 1.5 kW with rotor diameter of 85 mm and using 2G HTS tape with minimum bending diameter of 35 mm. In present work, the design of 2G HTS tape based superconducting rotor for a four-pole generator and corresponding excitation system are presented along with the electromagnetic analysis for the proposed HTS rotor for the estimation of flux density. Finally, an HTS coil is fabricated and tested up to its operating current.
