| Stacks of superconducting tapes can be used as trapped-flux magnets and applied in a fully superconducting motor. In such application, they can be subjected to an angled magnetising field. In this work, the results of the numerical analysis of the stacks with different sizes, magnetised by angled magnetic fields, are presented. The numerical model applied bases on H-formulation. The optimum number of tapes in which the magnetisation per tape is the highest is sought. The dependence is obtained and presented for 40 mm wide tapes, similar in size to the ones applied in a future motor. It was shown that the optimal number of tapes increases with the strength of the magnetising field and decreases with its deviation from the direction normal to the stack. |
