| current signature analysis: Induction Motor Fault Diagnosis Subrata Karmakar, Surajit Chattopadhyay, Madhuchhanda Mitra, Samarjit Sengupta, 2018-04-25 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. |

| current signature analysis: Physical Asset Management for the Executive Howard W. Penrose, 2008 Proper management of physical assets remains as the single largest business improvement opportunity in the 21st Century. Based upon the U.S. Census Bureau, an 1979 maintenance study performed by MIT and recent reliability and maintenance studies, the size of the asset maintenance industry in the USA was $1.2 trillion in 2005, in which $750 billion was the direct cost of poor physical asset maintenance and management. Of the $12.5 trillion GDP for the USA, an additional 20% was lost due to poor or improper physical asset investment while over 60% of businesses rely upon maintaining equipment reactively. Dr. Penrose discusses the strategies that must be applied to your business to take advantage of this last frontier in business improvement. Determine where you stand by asking yourself this one question: The next time you get on that elevator or airplane, what if they are maintaining it the same way you maintain your facilities and production equipment; would you want to ride? |

| current signature analysis: Electrical Systems 2 Abdenour Soualhi, Hubert Razik, 2020-04-14 Methods of diagnosis and prognosis play a key role in the reliability and safety of industrial systems. Failure diagnosis requires the use of suitable sensors, which provide signals that are processed to monitor features (health indicators) for defects. These features are required to distinguish between operating states, in order to inform the operator of the severity level, or even the type, of a failure. Prognosis is defined as the estimation of a systems lifespan, including how long remains and how long has passed. It also encompasses the prediction of impending failures. This is a challenge that many researchers are currently trying to address. Electrical Systems, a book in two volumes, informs readers of the theoretical solutions to this problem, and the results obtained in several laboratories in France, Spain and further afield. To this end, many researchers from the scientific community have contributed to this book to share their research results. |
