INVESTIGATION OF THE DYNAMIC PERFORMANCE OF HYSTERESIS MOTORS USING MATLAB/SIMULINK

Omer M. Awed Badeeb

   The hysteresis motor starts by virtue of hysteresis losses induced in its rotor. Hysteresis motors are widely used in small motor applications. In this paper the dynamic performance of hysteresis motors is investigated. A mathematical model is applied to analyze the transient and dynamic stability of this electrical machine type. The transient and dynamic stability studies examine the performance of the motor under transient condition and when the system is perturbed about some operating point, ie, small-signal analysis. In addition, in this paper, the mathematical based d, q axis model is incorporated in Matlab/Simulink tools for analysis and simulation purposes. This incorporation is considered a trend in applying new computerized tools in electrical machines simulation, design and analysis. The model offers a tool for studying the dynamic stability of the hysteresis motor for small-scale perturbations such as changes in motor's input supply voltage or frequency or in its output load torque as well as under other various conditions.

Keywords: hysteresis motor modelling, dynamic stability, Matlab/Simulink
