Abstract :
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 domain to the frequency domain. A Lissajoux curve formed of the two components is associated to the spectrum. Simulation results curried out for non defected and voltage unbalance motor show the effectiveness of the proposed method.
