Abstract: This paper proposes the application of high-voltage stator-cable windings in superconducting machines, based on the characteristics of strong magnetic fields and large air gaps. Cross-linked polyethylene cable winding can be employed to achieve a rated voltage of 35 kV in DC-field superconducting machines, thereby enabling a direct connection between the superconducting machine and the power grid, eliminating the need for transformers. We first, through finite-element analysis, demonstrate that the proposed high-voltage high-temperature superconducting machine not only meets the requirement of a 35-kV rated voltage, but also exhibits minimal flux leakage, torque fluctuation, and harmonic distortion. We then compare three candidate Types to discuss the tradeoff between the multi-group superconducting field winding arrangement and machine performances. We propose inverted trapezoidal superconducting field winding as a promising candidate, because it has minimal superconductivity material usage, the largest safety margin for the superconducting coils (SC), low thrust ripple, and low total harmonic distortion with the desired 35-kV-rated voltage. Finally, through large-scale design parameter sweeping, we show how we selected the optimal parameters for field winding and validated them by the finite-element method.
