Analysis of hysteresis motor using finite element method and magnetization-dependent model

In this paper, finite element analysis (FEA) of a hysteresis motor using a magnetization-dependent model is presented. The hysteresis loop in the hysteresis ring is calculated from the maximum flux density which is obtained by the FEA. The proposed method is applied to a sample motor and the simulation result shows a very good agreement with the experimental one. Various formulations for hysteresis region are compared and it is found that pseudo-permeability method is most effective.
