Abstract
Electric-drive Aeropropulsion is one of the key technologies in design of future aircrafts because the electric motor drive has high efficiency and the this would reduce operational cost and pollutant emission. This paper discusses the optimization of electromagnetic design of superconducting motors. Finite element analysis, multi-objective genetic algorithm and analytical equations are applied in the optimization. Power density, power loss including AC loss of superconducting materials, and torque ripple are considered in the objective function. The results of optimization suggest that the application of superconducting motor is feasible for electric-drive aeropropulsion with power density higher than 16.4 kW/kg.
