Abstract

In this paper the circuit-oriented model of the 3-phase induction machine with a double stator winding was developed. The double winding (dual winding) is created by two 3-phase windings mutually displaced by 30 electrical degrees. The machine model is presented as the circuit composed of resistances, inductances and controlled electrical sources. It results from the transformed voltage equations. Such a model is not offered by the Simulink library, however it can be directly introduced using Sim-Power-Systems and additionally into other circuit simulators as the Spice family programs. The whole model can be masked and connected with other models of power electronics, electrical sources or various electrical and mechanical devices. Operation of the frequency controlled drive, where the both stator windings were supplied with two current source inverters, illustrates application of this circuit oriented machine model. Further applications have been left for the users invention.
