Abstract

This paper deals with 3-D magnetic flied analysis of superconducting machines using analytical method, which consists of space harmonic analysis and image method. For prediction of magnetic field distributions produced by field winding, 3-D magneto-motive force distribution by field winding is defined by magnetization vector. In order to get 3-D flux distributions, 2-D flux distributions are first calculated in space harmonic analysis and 3-D weighting factors for radial flux component according to position to z -axis direction are calculated in image method. 3-D weighting factors are multiplied to two-dimensional flux distributions, and then 3-D magnetic field distribution is calculated. Finally, magnetic field distributions and computation time are compared with 3-D finite element analysis.
