Design and electromagnetic analysis of a superconducting rotating machine

A superconducting synchronous motor with an inductor containing bulk high temperature superconductor and BiSrCaCuO wires has been studied in this paper. The principle of operation is based on the interaction between the two spatial variable magnetic fields in the motor air gap. One of the two aforementioned magnetic fields is produced by the superconducting inductor based on magnetic shielding of high temperature superconductors. A procedure is developed to calculate the magnetic field produced by the inductor in the environment of the commercial finite element code ANSYS. The HTS motor is designed to develop 100 hp (the rated power).
