New approach to study HTS bulk behavior for a fully superconducting motor design

Abstract

This paper describes a method for calculating the induced currents in a high temperature superconducting bulk (HTS) used in a superconducting synchronous motor (SSM) design. knowledge of these currents leads to useful information concerning the real behavior of HTS material with respect to external magnetic eld and therefore operating limits of the superconducting motor. This approach based on the calculation of the total electrical parameters of the equivalent electrical circuits of studied structure. Very impressive results are observed. The main objective of this work is to show the feasibility of this new approach for the study of superconducting machines designed with massive HTS materials.
