A Fast Numerical Modeling Approach Based on Boundary Field Method for Calculating AC Losses in Superconducting Motors

To improve the computational efficiency of numerical methods for calculating ac loss in HTS motor, a new method called ‘Boundary field method’ is proposed this article. This combines strength ANSYS and COMSOL, which can reduce complexity modeling computation time. In article, three finite-element based models, as case studies, were developed 100-kW superconducting induction motor. Model A models entire motor COMSOL using A-H formulation, considering nonlinear E–J relationship high temperature tapes, calculate directly; Combining another two models: B (the same ANSYS) model C (only stator windings COMSOL) achieve loss. The AC calculation error between two-layer one slot 2.5% 7%, respectively. These results conclude effectiveness accuracy “boundary method.” More importantly, time reduces dramatically from 48 hours to only 2 approach. accurate computationally efficient approach could be used various types applications future.
