Download or read book Induction Motor Fault Diagnosis written by Subrata Karmakar and published by Springer. This book was released on 2016-04-04 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2016-08-12 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thesis (M.A.) from the year 2013 in the subject Electrotechnology, Warsaw University of Technology (Electrical Engineering), language: English, abstract: 3-Phase induction motors are widely used as a source of mechanical power for effective operation and low costs. The abnormalities have to be detected in advance to avoid the motor breakdown and the cost associated restrain of plant production. This work discusses current and flux leakage spectral analysis techniques for the diagnosis of broken rotor bars and shortcircuited turns in induction motor fed from different AC sources. In spite of recent development of various types of models toward motor faults diagnosis and examining different problems associated with 3-phase induction motors the signal spectral analysis is considered as one of most important approaches. Most of the models from simple equivalent circuit to more complex d-q and a-b-c models and lastly developed hybrid models are provided for the integration of different forms of current and/or voltage unbalance. Generally, techniques that relate to asymmetry identify asymmetrical motor faults. Frequency converters in many applications feed induction motors. Such applications, which play a major role in industry, are growing at a high rate, allow to use 3-phase induction motor as variable speed applications. This paper proposes application of spectral signature analysis for the detection and diagnosis of abnormal electrical and mechanical conditions, which indicates chosen faults in induction motor fed by frequency converter.
Book Synopsis Fault Harmonic Analysis of Three Phase Induction Motor Line Currents by : Michael Staley
Download or read book Fault Harmonic Analysis of Three Phase Induction Motor Line Currents written by Michael Staley and published by . This book was released on 1993 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The present methods of testing three phase induction motors is inefficient in the sense that motors have to be taken offline to effect these tests. Predictive maintenance techniques require better prediction of faults before they occur. The purpose of this project was to provide the necessary proof that with the proper diagnostic equipment and analysis techniques the online electrical condition of three phase, induction motors can be determined and predicted to follow a certain path. Certain faults such as winding assymetries, eccentricities and squirrel cage faults were investigated in the report, as well as tested and analysed on three phase induction motors. The results, being positive, help to reinforce the past research mentioned in the report. The testing and analysis of induction motors, in this project, illustrates how that with a more modern approach to the testing of · induction motors the fault condition of these motors can be diagnosed online. To increase the likelyhood of detection further recommendations have been made for future reference. " -- Abstract/Synopsis.
Book Synopsis Simulation of Electrical Faults of Three Phase Induction Motor Drive System by : Muhammad Alif Mohd Nor
Download or read book Simulation of Electrical Faults of Three Phase Induction Motor Drive System written by Muhammad Alif Mohd Nor and published by . This book was released on 2009 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: The title of this project is Simulation of electrical faults of three phase induction motor drive system. Induction motor or asynchronous motor is a type of alternating current motor where power is supplied to the rotor by means of electromagnetic induction. Induction motor is now the preferred choice for industrial motor due to their rugged construction, absence of brushes (which are required in most DC motors) and the ability to control the speed of motor. The faults that can occur in the three-phase induction motor and its driver can be divided into two parts; internal and external faults. The internal fault of induction motors account for the proportion almost more than 70% of induction motor failures. This project will cover and study a few type of internal and external faults, which is the stator inter-turn short circuit, unbalanced voltage supply and the single phase open circuit fault. The study of induction motor is crucial and important so that the lifespan of the motor can be prolonged. In this project MATLAB SIMULINK is used to simulate the induction motor faults and analyze the condition. The simulation file is then compiled along with a GUI to simplify the overall process and improves the user friendliness to users.

Book Synopsis Incipient Detection of Faults in Three-Phase Induction Motors Using Stator Current Spatial Angular Vector Analysis by : R.A Gupta
Download or read book Incipient Detection of Faults in Three-Phase Induction Motors Using Stator Current Spatial Angular Vector Analysis written by R.A Gupta and published by . This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The detection of motor faults at their incipient stage is gaining importance as it leads to increased reliability and reduced machine downtime. The stator current analysis has caught the attention of researchers as a mature and simple technique for induction motor fault detection and identification. In this paper, angular space vector analysis of the induction motor stator current for fault identification has been investigated. The tracking of spatial angular vector profile of stator current (Parke's vector) is used to identify the degrading health condition of induction motors. Any significant deviation in the shape of spatial angular vector is an indicator of the inset of irregularities - mechanical or electrical - in the induction motor. Three major types of induction motor faults - bearing fault, broken rotor bar fault, and unbalanced supply faults - have been experimentally investigated. The experimentation has been performed on a 3(*), 1.5 kW, 4 poles, 1440 RPM, ABB squirrel cage motor. The motor setup was mechanically loaded to operate at various loads. The TMS 320F420 DSP-based dSPACE DS 1104 control card has been used to carry out the experimentation. The softwares used include MATLAB® ver. 2006 and dSPACE controldesk.

Book excerpt: With countless electric motors being used in daily life, in everything from transportation and medical treatment to military operation and communication, unexpected failures can lead to the loss of valuable human life or a costly standstill in industry. To prevent this, it is important to precisely detect or continuously monitor the working condition of a motor. Electric Machines: Modeling, Condition Monitoring, and Fault Diagnosis reviews diagnosis technologies and provides an application guide for readers who want to research, develop, and implement a more effective fault diagnosis and condition monitoring scheme—thus improving safety and reliability in electric motor operation. It also supplies a solid foundation in the fundamentals of fault cause and effect. Combines Theoretical Analysis and Practical Application Written by experts in electrical engineering, the book approaches the fault diagnosis of electrical motors through the process of theoretical analysis and practical application. It begins by explaining how to analyze the fundamentals of machine failure using the winding functions method, the magnetic equivalent circuit method, and finite element analysis. It then examines how to implement fault diagnosis using techniques such as the motor current signature analysis (MCSA) method, frequency domain method, model-based techniques, and a pattern recognition scheme. Emphasizing the MCSA implementation method, the authors discuss robust signal processing techniques and the implementation of reference-frame-theory-based fault diagnosis for hybrid vehicles. Fault Modeling, Diagnosis, and Implementation in One Volume Based on years of research and development at the Electrical Machines & Power Electronics (EMPE) Laboratory at Texas A&M University, this book describes practical analysis and implementation strategies that readers can use in their work. It brings together, in one volume, the fundamentals of motor fault conditions, advanced fault modeling theory, fault diagnosis techniques, and low-cost DSP-based fault diagnosis implementation strategies.

Book Synopsis Open-Phase Fault Operation on Multiphase Induction Motor Drives by : Hugo Guzman
Download or read book Open-Phase Fault Operation on Multiphase Induction Motor Drives written by Hugo Guzman and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiphase machines have been recognized in the last few years like an attractive alternative to conventional three-phase ones. This is due to their usefulness in a niche of applications where the reduction in the total power per phase and, mainly, the high overall system reliability and the ability of using the multiphase machine in faulty conditions are required. Electric vehicle and railway traction, all-electric ships, more-electric aircraft or wind power generation systems are examples of up-to-date real applications using multiphase machines, most of them taking advantage of the ability of continuing the operation in faulty conditions. Between the available multiphase machines, symmetrical five-phase induction machines are probably one of the most frequently considered multiphase machines in recent research. However, other multiphase machines have also been used in the last few years due to the development of more powerful microprocessors. This chapter analyzes the behavior of generic n-phase machines (being n any odd number higher than 3) in faulty operation (considering the most common faulty operation, id est the open-phase fault). The obtained results will be then particularized to the 5-phase case, where some simulation and experimental results will be presented to show the behavior of the entire system in healthy and faulty conditions. The chapter will be organized as follows: First, the different faults in a multiphase machine are analyzed. Fault conditions are detailed and explained, and the interest of a multiphase machine in the management of faults is stated. The effect of the open-phase fault operation in the machine model is then studied. A generic n-phase machine is considered, being n any odd number greater than three. The analysis is afterwards particularized to the 5-phase machine, where the open-phase fault condition is managed using different control methods and the obtained results are compared. Finally, the conclusions are presented in the last section of the chapter.
