Cause, analysis and prevention of motor shaft failures

The author has published previous papers focused on stator, rotor and bearing failures and established a methodology for the analysis of these failures. This work is the result of a taxonomic study covering his 40 year career. The purpose of this paper is to identify the various shaft failures and their causes that one could expect to find on an induction motor. Much of this work is also applicable to other types of equipment. The previous papers that have applicable material are referenced for the readers' convenience.
