Possibility for analysis of the reluctance synchronous motors dynamic stability

This paper analyzes the dynamic stability of a reluctance synchronous motor rated at 1,5 kW by means of some simulations in dynamic regime. For doing this, there are presented the two axes theory mathematical model of the motor, the Matlab-Simulink program conceived with the help of this model and the simulations that have been obtained this way. Two of the most common possible disturbances are considered: the decrease of the supply voltage and saltus of the resistant torque during the operation. In the final part of the paper there are presented the experiments and the conclusions that are obtained by finalyzing the study.
