Abstract :
According to earlier work and papers by other authors, the main flux path of an induction machine is not only saturated due to the magnetizing current or, in other words, ldquothe magnetizing inductance can be modeled as a function of torquerdquo. In the paper a method is proposed to extend the induction machine´s standard fundamental wave model taking into consideration the changes of the main inductance in dependence of the magnetizing and the torque building component of the stator current. Furthermore, a method is presented to estimate the required parameters from measurements carried out during normal operation of the induction machine. Validation is achieved via FEM calculations and additional measurements.
