Abstract

This paper presents how to determine the thickness of the hysteresis ring of hysteresis motor using the finite element method combined with a vector hysteresis model. From the magnitude and direction of the magnetic field intensity, the magnetization of each ring element is calculated by the vector hysteresis model and the torque can be obtained from the vector sum of each torque of each element or from the area of the hysteresis loop. From these calculations, it is found that the motor torque is not proportional to the thickness of the ring. As a result, an optimum thickness of the hysteresis ring exists and it can be determined by the proposed method
