High AC loss in stator windings is one of the key challenges in realizing fully high-temperature superconducting (HTS) wind turbine generators, which offer significant advantages in compactness and weight compared to conventional machines. Among the sources of AC loss, the perpendicular magnetic field component (relative to the HTS tape surface) is particularly dominant, while the parallel field contributes much less. Therefore, minimizing the perpendicular field in the stator windings is essential when designing a fully HTS generator. In this work, we present a 5 MW-class, air-cored, axial-flux fully HTS wind turbine generator modeled using the finite element method (FEM). The T-A formulation and interpolated Jc(B) characteristics are used to simulate the electromagnetic behavior of the HTS windings. A moving mesh approach is employed to simulate the rotor movement. Simulation results show that the outer-stage stator windings experience significantly higher AC loss than the inner-stage windings, despite delivering the same power output. By optimizing the rotor end-winding geometry, the perpendicular magnetic field in the outer-stage windings was significantly reduced, resulting in a 77% decrease in total AC loss across the HTS stator windings.
