摘要：
The 3D finite element model of an induction motor is considered for the evaluation of the influences of the static eccentricity fault on the stator current, motor torque, rotor unbalanced force, magnetic flux density in the airgap and on the voltage repartition in the elementary coils of the stator winding. Time time variations of these quantities during the no-load motor start-up are computed and compared for healthy and faulty operation states of the motor. The existence of the static eccentricity fault is consistently reflected by the rotor unbalanced force and by the values of the voltage in successive elementary coils of the stator winding.
