This paper addresses the complex modeling of a multi-phase asynchronous motor with star-connected and delta-connected stator phases. The model is obtained using a complex rectangular transformation that reduces the number of complex internal variables and is graphically represented using the Power-Oriented Graphs technique. The dynamic equations have been defined considering the stator phases star-connected and delta-connected, proving that in both cases the internal complex model does not change. Finally some simulation results have been presented to show the effectiveness of the modeled system and the contribution of the star-delta transformation in terms of provided torque.

Abstract
This paper addresses the complex modeling of a multi-phase asynchronous motor with star-connected and delta-connected stator phases. The model is obtained using a complex rectangular transformation that reduces the number of complex internal variables and is graphically represented using the Power-Oriented Graphs technique. The dynamic equations have been defined considering the stator phases star-connected and delta-connected, proving that in both cases the internal complex model does not change. Finally some simulation results have been presented to show the effectiveness of the modeled system and the contribution of the star-delta transformation in terms of provided torque.
