Magnetization characteristics of Bi-2223 superconducting bulk disk in a rotating magnetic field are analyzed with the use of 3-D finite element method. The disk is utilized as a rotor for an axialtype superconducting motor. Power-law approximation as well as Kim model is introduced in order to express the constitutive relation between electric field vs. current density for the analysis. It is shown that the analysis results of the hysteresis loops agree semi-quantitatively with the measurements. The dependency of the applied field amplitude upon the magnetization characteristics and its relation to the standstill torque will also be discussed based on the analysis.
