Abstract
In this paper, a transient model of the faulty machine is
developed. The model is referred to a three phase stator
winding, while the rotor has been represented by all the
meshes allowing for the representation of various faults.
The model is based on coupled magnetic circuit theory and
incorporates non sinusoidal air-gap magneto motive force (MMF)
produced by both stator and rotor, therefore it will include
all the space harmonics in the machine. Simulation and
experimental results were first used to identify low and
high frequency spectral components created by rotor
anomalies in the stator current spectrum. This paper then
presents an approach for motor rotor fault diagnosis using
neural networks. The proposed methodology has been
experimentally tested on a 5.5Kw/3000rpm induction motor.
The obtained results provide a satisfactory level of
accuracy.
Keywords:
Induction machines, coupled
magnetic circuit, rotor failures, Neural networks,
diagnostic.

Yassine Koubaa was born in Sfax, Tunisia in
1961. He received the B.S. and DEA degrees in 84 and
86, respectively, the Doctoral thesis in 1996, the
‘‘Habilitation Universitaire’’ (HDR) from the
National Engineering school of Sfax (ENIS) all
in electrical engineering. From 1989 to 1996, he
was an Assistant professor in the Electrical
Engineering Department of ENIS. In september
1997, he has been an Associate Professor.
Since September 2005, he becomes a full Professor
at the same university. His main research
interests cover several aspects related to
electrical machines, including systems
identification, advanced motion control and
diagnostics. He has authored more than 60 papers in
international conferences and technical journals in
the area as well as many patents. He serves as a
member of the Scientific and the Technical Program
Committees of several international conferences and
technical journals in the motor drives fields. |

Ahmed Toumi
(born on 1952), Professor in the Sfax Engineering
National School (ENIS), received the Electrical
Engineering Diploma from (ENIS/Tunisia), the DEA
(Master) in Instrumentation and Measurement from
University of Bordeaux-1/France in 1981 and the
Doctoral Thesis from the University of Tunis in
1985. He joined the Sfax Engineering National School
(ENIS), as an Associate Professor of Electric
Engineering, since October 1981. In 2000, he
obtained the University Habilitation (HDR) from the
Sfax Engineering School (ENIS). He is at present the
Director of the Electrical Engineering Department in
ENIS. The main research area concerns the modelling,
the stability of the electric machines, the
electrical networks, the fuzzy logic control. He is
the Head of the Research Unit of Industrial
Processes Control (UCPI) of the Sfax University.
Since 2002, he is the President of the
international conference on Sciences and
Techniques of Automatic
control (STA) which have
taken place
in a number of
tourist cities of Tunisia. |
