Electrical asymmetry level influence on quality attributes of an induction motor

The paper is devoted to the evaluation of rotor phase asymmetry level on induction motor operation quality. The problems and characteristic features of an induction motor asymmetric modes modeling, taking into account the saturation of the magnetic circuit are reflected. The modification of the classic mathematical model for currents and torque calculating in conditions of rotor circuit asymmetry is presented, and the results of numerical simulation of this mode are shown. Analysis of the distinctive features of the selected mode compared to the symmetric mode of an induction motor is performed.
