Analysis of the Mechanical Characteristics of a 17-MW-Class High-Temperature Superconducting Synchronous Motor

This paper presents an analysis of the mechanical characteristics of a 17-MW-class high-temperature superconducting (HTS) synchronous motor. The fundamental electromagnetic, structural, and thermal design must be accompanied to maintain the reliability of an HTS rotating machine when designing an HTS synchronous motor with an HTS wire with a high current density instead of a copper wire used in a conventional rotating machine. Therefore, we analyze the structural characteristics from two perspectives using three-dimensional (3D) finite-element analysis for the structural design of a 17-MW-class HTS synchronous motor that is intended to be utilized for ships with electric propulsion.
