Spectral analysis of stator current allows us to study and identify the saturation harmonics for the case of a healthy motor and a motor with an eccentricity fault This paper describes the influence of magnetic saturation on the diagnosis of mixed eccentricity fault in squirrel induction motors by a modeling and a simulating work. The effect of eccentricity and saturation are included in the calculation...
This paper is a continuation of a previous work regarding the induction motors diagnosis problem. An on-line fault detection strategy has been proposed using a graphical signature generation tool. In this work, the graphical tool is used for an off-line diagnosis including isolation and estimation. The underlying diagnosis problem corresponds to variations affecting three of system's parameters, namely,...
Due to its simple construction, low cost, manufacture, and its robustness. The use of induction motors is rapidly and increasingly growing in the industry especially in highly important sectors. This leads us to a serious focus on their operation and their availability. The early detection for motor deterioration can increase plant availability and safety in economical way, help to avoid expensive...
Through the increasing use of electric actuators, the induction motor is now major in industrial applications and takes a particular interest for applications requiring high power and variable speed robustness and for its simplicity and its low cost. The early detection for motor deterioration can increase plant availability and safety in an economical way. To improve the reliability as a whole, a...
In this paper, a new method for induction motor fault diagnosis is presented. It is based on the so-called voltage Park components of an auxiliary winding which is a small coil inserted between two of the stator phases. Expressions of the inserted winding voltage and its Park components are presented. After that, discrete Fourier transform analyzer is required for converting the signals from the time...
