Abstract
The aim of this paper is to analyze the performance of 3-phase wound rotor induction motor (WRIM) under rotor windings asymmetry. The behavior of WRIM were simulated under healthy and asymmetry conditions. With the aid of simulation results, variation of motor speed, electromagnetic torque, stator and rotor currents have been analyzed. To validate the simulation results a series of experiments were conducted for healthy and asymmetry rotor circuit. The results proved that for the asymmetry rotor windings conditions the stator and rotor current increase while the motor speed decrease and the ripples of speed and electromagnetic torque increase. The paper proved that the performance of the motor in the asymmetry rotor case is directly affected by the connection of rotor windings.
