摘要：

High power density motors are required for electric propulsion aircrafts. The highest power density of the conventional motor is reported as 5.2 & x00A0;kW & x002F;kg up to now. Superconducting rotating machines have a potential to realize higher power density due to its high current density and a large magnetic field property. In this study, the induction motor with air-cored superconducting armature windings was conceptually designed. The output power range was 3 to 6 & x00A0;MW and the output power density aimed to be over 20 & x00A0;kW & x002F;kg. The armature voltage should be below kV-class and joule loss below 122 & x00A0;kW. The target efficiency was over 95 & x0025;. The electromagnetic design and analysis were carried out by JMAG Designer. The number of magnetic poles and operating temperatures were set as two poles and liquid hydrogen temperature of 20 & x00A0;K, respectively. The parameter was power frequency in the range of 100 & x2013;250 & x00A0;Hz. As a result, all the requirements were satisfied when the power frequency was 130 & x00A0;Hz. The feasibility of the MW-class superconducting induction motor was investigated, and in conclusion, the superconducting induction motor can be applied to the aircraft propulsion system.
