3D modeling of high temperature superconducting hysteresis motor using COMSOL multiphysics

Abstract

This paper presents 3D modeling of hysteresis motor with high temperature superconducting material in the rotor using Finite Element based solver software COMSOL Multiphysics. Due to the anisotropic property of HTS material, magnetic flux distributions are non-uniform in different axes. Therefore, analysis of HTS hysteresis motor using two dimensional modeling cannot provide high degree of accuracy. Thus, three dimensional modeling is developed for more accurate, precise and realistic results. The magnetic fields around and inside the motor can be computed accurately with the help of proposed three dimensional modeling of motor. To improve the performance in comparison of conventional hysteresis motors such type of motors are developed. The measured parameters are compared with the experimental results. Simulations are done with the help of MATLAB and COMSOL Multiphysics software.
