Abstract
A Superconducting Rotary Machine (SRM) is characterized by an air-cored machine with its rotor iron and stator iron teeth removed. For this reason, the SRM is featured by 3D magnetic flux distribution, which decreases in the direction of axis, Therefore, 3D magnetic field analysis method is required to know about characteristic of magnetic field distribution of SRM, In this paper, 3D flux distribution of SRM is calculation by using analytical method. The magnetic field distribution due to the field coils use of the Biot-Savart equation. The magnetic core is represented by magnetic surface polarities. The paper describes the combined use of above methods for the total computation, and compares analytical method and 3D FEM(Finite Element Method) results.
