This paper presents an efficient modelling strategy for superconducting motors, combining the time-space extrusion (TSE) method and the <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T-A</i> formulation. Taking a newly designed air-cored 100-MW fully superconducting double-rotor motor (FSC-DRM) for direct-drive marine propulsion as an example, the proposed TSE and <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T-A</i> combined method can achieve a 52% reduction in computational time compared to the conventional <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">T-A</i> model. In addition, compared to the AMSC 36.5-MW marine propulsion motor, with the same geometric size, the proposed FSC-DRM achieves a 2.1 times higher power density with an efficiency reaching 98.8%, considering the cooling penalty.
