This book covers the diagnosis and assessment of the various faults
which can occur in a three phase induction motor, namely rotor
broken-bar faults, rotor-mass unbalance faults, stator winding
faults, single phasing faults and crawling. Following a brief
introduction, the second chapter describes the construction and
operation of an induction motor, then reviews the range of known
motor faults, some existing techniques for fault analysis, and some
useful signal processing techniques. It includes an extensive
literature survey to establish the research trends in induction
motor fault analysis. Chapters three to seven describe the
assessment of each of the five primary fault types. In the third
chapter the rotor broken-bar fault is discussed and then two
methods of diagnosis are described; (i) diagnosis of the fault
through Radar analysis of stator current Concordia and (ii)
diagnosis through envelope analysis of motor startup current using
Hilbert and Wavelet Transforms. In chapter four, rotor-mass
unbalance faults are assessed, and diagnosis of both transient and
steady state stator current has been analyzed using different
techniques. If both rotor broken-bar and rotor-mass unbalance
faults occur simultaneously then for identification an algorithm is
provided in this chapter. Chapter five considers stator winding
faults and five different analysis techniques, chapter six covers
diagnosis of single phasing faults, and chapter seven describes
crawling and its diagnosis. Finally, chapter eight focuses on fault
assessment, and presents a summary of the book together with a
discussion of prospects for future research on fault diagnosis.
