This paper reports on the analysis results of hysteresis losses when a rotating magnetic field, including harmonic magnetic field components, is externally applied to the filament model of an MgB2 superconducting wire in the armature windings of a fully superconducting synchronous motor for aircraft electric propulsion systems. First, a model of the fully superconducting synchronous motor is constructed in JMAG-Designer, and the magnetic field components in the armature windings are obtained by electromagnetic field analysis. Then, a filament model of the MgB2 superconducting material is built in COMSOL, and its AC losses are calculated by electromagnetic field analysis. After confirming that the hysteresis loss follows the theoretical equation when the externally applied rotating magnetic field is sinusoidal with only a fundamental component, the effect of superimposed harmonic components on the hysteresis loss is considered.
