Design and Characteristics Comparative Research of 2MW Class Fully Air-core Superconducting Motor

The imperative of shifting the transportation sector towards environmentally sustainable electric propulsion has become unmistakable. Superconducting motors have emerged as a revolutionary solution, offering intrinsic benefits such as compactness, lightweight design, and exceptional efficiency in comparison to conventional motors. These attributes hold immense promise, particularly when harnessed in the propulsion systems of expansive maritime vessels and aviation crafts, opening up previously unattainable frontiers of power density. In this paper, a 2MW fully air-core superconducting motor was designed for electric propulsion applications. Subsequently, its characteristics were compared with those of an iron-core superconducting motor. Through the analysis of parameters such as weight, power density, and magnetic flux density, it was conclusively established that for aviation and marine propulsion systems, the more suitable motor is the fully air-core superconducting motor.
