Identification of the Active Resistances of the Stator of an Induction Motor with Stator Windings Dissymmetry

The article deals with an equation obtained for determining an active resistance of the stator phase. The equation consists of the ratio of the mean values of the current and voltage integral functions in the steady-state operating mode. We substantiated the possibility of using this method for parametric asymmetry of an induction motor caused by a short-circuit in one of the phases. We obtained dependences of the active resistance and inductance of the phase dissipation of an induction motor in the case of a turn-to-turn fault. We developed the mathematical model of an induction motor in phase coordinates, which takes into account the parametric asymmetry of the individual phases of the induction motor. The limits of this method were determined by the dependence on the turn-to-turn fault.
