Hysteresis Torque Analysis of Permanent Magnet Motors Using Preisach Model

摘要

In the paper, the method of computing hysteresis torque of permanent magnet motor using Preisach model is studied. Generally, finite element method (FEM) with Preisach model is very complicate because of nonlinear characteristic of materials. Preisach hysteresis model is not combined with solver but post-processor of FEM. This process is easy to find hysteresis loop of soft magnetic material.
