Abstract

In this study, a 1 MW 16-pole/12-slot double-rotor flux switching machine is designed which uses superconducting magnetic shields and high-temperature superconductor field coils. The proposed motor comprises an air-core stator that carries both armature and field windings. Aluminum Litz wire at T=95K is used for the armature conductors, and yttrium barium copper oxide superconductor is used for the field coils at T=65 K. The inner and outer rotors are laminated Hiperco50, and the superconducting magnetic shields are placed between the rotor teeth. The superconducting magnetic shields have a significant impact on the machine's performance, including output power density and efficiency. The motor with shields delivers a high-power density greater than 64 kW/kg and an efficiency of ≥98.83%.
