Abstract

Due to the advantages of high magnetic field and ultra-compactness of superconducting disk-up-down-assembly (DUDA) magnets, they are promising in superconducting motors. To study the current density distribution and the critical current of a DUDA magnet, numerical simulation based on Comsol is employed by taking into consideration of the field dependence of the critical current from short-sample measurement. In order to have a uniform and low joint resistance, influence factors of the lap joint resistance are investigated and a new configuration of the DUDA magnet is proposed in the paper. To study the feasibility of the proposed magnets, preliminary studies of a 4-layer superconducting DUDA magnets are carried out by experiments in liquid nitrogen. It shows that the new configuration of the DUDA magnet can significantly reduce the joint resistance and the joint resistances are more uniform.
