Abstract

This paper focuses on the 2G HTS armature winding design for fully HTS machines. The main challenge for HTS armature windings is the ac loss calculation. This paper proposes an effective way to estimate 2G HTS armature efficiency. The originality of ac loss calculation is effectively coupling a machine model with a HTS model using boundary conditions to simulate machine environment while considering material anisotropy. The paper then uses H formulation to estimation the total armature ac loss for a 1-MW propulsion motor. The ac loss is calculated for different electrical loadings and magnetic loadings. A new double-layer armature winding is proposed to reduce the spatial harmonics of HTS armature.
