Torque computation of hysteresis motor using finite element analysis with asymmetric two dimensional magnetic permeability tensor

This paper deals with the analysis of the generated torque of the hysteresis motor using finite element method. The material property of the hysteresis ring in the hysteresis motor is characterized by the asymmetric two dimensional magnetic permeability tensor. The torque has been computed effectively by using permeability tensor instead of full hysteresis modeling or Maxwell stress tensor. The proposed method has been applied to the sample hysteresis motor to compute the torque and the results are in good agreement with the experimental results.
