Dynamic Modeling and Load Characteristics of Hysteresis Motor Using Preisach Model

In this paper, a strict dynamic analysis for hysteresis motor is executed using a hysteresis motor equivalent circuit including eddy current and inverse Preisach model. For the permeability of the hysteresis ring, the hysteresis motor steady-state analysis including the inverse Preisach model is used. That is, it is possible to analyze the rotor characteristics according to the applied voltage. The Hysteresis loop is approximated to an ellipse loop for dynamic analysis. The variation of speed, torque, current etc. of the motor from starting to steady-state are calculated considering inertia, friction, and windage load. From these result, the load characteristics are analyzed.
