Summary

Chapter 4 presents an introduction to vibration spectrum analysis to diagnose faults in rolling element bearings in induction motors.This chapter is a precursor to the presentation of industrial case histories in Chapters 5 to 8 using conventional vibration spectrum analysis (VSA) to diagnose the onset of faults in rolling element bearings before actual bearing failures occur. It is emphasised that previously published books and papers that cover the theory and application of vibration monitoring to diagnose faults in rolling element bearings assume that vibration transducers such as accelerometers can be always placed on the bearing housings.In many cases access to bearing housings is not practically possible on induction motors and this a key fact which is demonstrated in this book.
