Abstract:In the paper modeling of main inductances for mathematical models of induction motors is applied to study the effects caused by a rotor eccentricity and saturation effects. All three possible types of eccentricity: static, dynamic and mixed are modeled. The most important parameters describing rotor eccentricity include self and mutual inductances of the windings. The structural changes of the permeance function as a result of eccentricity appearance and the Fourier spectra of inductances in occurrence of saturation for each case are determined in the paper. The presented algorithm can be used for the diagnostically specialized models of induction motors.

“…Thus, this method is effective for diagnosis of the winding itself. However, because typical motors include a rotor and the stator and the rotor interact, capacitive coupling between the two may be present [11]. For this reason, even in the absence of changes in the state of the winding, the observed voltage waveform differ depending on the position of the rotor, and accordingly the distortion area may also have various values.…”

SUMMARY Short‐circuit faults in windings due to the deterioration of insulation is among the most common faults in motor drive systems. An easy and effective fault diagnosis method is urgently required to ensure highly reliable operation. This paper proposes a novel method for the diagnosis of short‐circuit faults in stator winding inside a low‐voltage induction motor without removing the rotor, by performing an impulse voltage test. As the rotor does not need to be removed from the motor in this novel diagnosis method, the method can be put to practical use. In this study, first, several impulse voltage tests are carried out on the stator windings of motors. Second, the values of two features that represent the characteristics corresponding to the condition of the motor are calculated, and it is found that the shape of the feature distribution does not depend on the rotor position but on the condition of the winding. Third, the distance between the feature distribution for the healthy motor and features obtained from a target motor is calculated. On the basis of this distance, the condition of the stator winding inside the induction motor is determined. The effectiveness of the proposed diagnosis method is verified by performing experiments that involve several motors with healthy and faulty windings.

“…Surge test, que usa adaptación de impedancia (impedance matching) al aplicar una sobretensión (surge), es un método bien conocido para el diagnóstico de fallas en el bobinado [SID05], [THO95], [KOH99]. Sin embargo, Huang et al [HUA07] introdujeron un nuevo método para la detección de excentricidad del rotor usando este procedimiento. Según ellos, el grado de excentricidad del entrehierro afectaría a la frecuencia de resonancia de una sobretensión sinusoidal.…”

“…La amplitud de la componente fundamental en el dominio de la frecuencia de un MI con fallo fue comparado con datos históricos, obtenidos de un motor sano, para indicar la severidad del fallo. Finalmente, ellos afirman que la prueba de sobretensión (surge test) es un método efectivo, económico y confiable que es particularmente útil en el mantenimiento predictivo de rutina [HUA07].…”
