Simulation of High Temperature Superconducting Hysteresis Motor using MATLAB and COMSOL Multiphysics

In this paper, a 2-pole, 50 Hz high temperature superconducting hysteresis motor has been numerically simulated using finite element method for its performance calculation. In this high temperature superconducting hysteresis motor, conventional copper winding is used in stator and the rotor consists of high temperature superconducting material which possess higher flux density consequently current density gets increased and the developed power also gets increased. To reduce the huge investments, errors and computational time for this work, numerical simulations are preferred over practical experiments. The performance parameters are compared with that of the conventional hysteresis motor in which ferro-magnetic material is used as a rotor. All the simulations are performed using MATLAB and partial differential equation based module of COMSOL Multiphysics software with proper boundary conditions. The simulation result shows a good agreement with the experimental results.
