Phd thesis on condition monitoring of induction motor in , jim gray organized the first summer institute, the bay area writing project at uc berkeley he tells us what we least want to hear about their terror, pain and rage. Condition monitoring and fault diagnosis of an induction motor are of great importance in the production line it can reduce the cost of maintenance and risk of unexpected failures by allowing the early detection of catastrophic failures. Induction motor is inherently reliable and requires minimum maintenance however, many companies are still faced with unexpected system failure and reduced induction motor lifetime this gives rise to the need for maintenance strategy based on condition monitoring, which can be addressed by monitoring and analysing the real-time signals of the.
