Hysteresis Modeling of Magnetic Devices based on Reluctance Network Analysis

In research and development of electrical machines, establishment of a method for quantitatively calculating iron loss including magnetic hysteresis behavior is required. In a previous paper, a novel magnetic circuit model incorporating a play model, which is one of the phenomenological models of magnetic hysteresis, was proposed. It was clear that the proposed model can calculate the hysteresis loop of the magnetic reactor with high speed and accuracy. This paper describes that the play model is applied to reluctance network analysis (RNA), in order to estimate the iron loss of electric machines with more complex shape such as electric motors.
