Book excerpt: Broken rotor bars are a common cause of induction motor failures. In the past, the detection of broken rotor bars has primarily been limited to non-operating, and typically, disassembled machines. The ability to detect broken rotor bars while the machine is operating at normal speed and load is desirable. In support of the ongoing development of a failure analysis system for electrical machines, this thesis evaluates the method of using stator currents and voltages to detect the presence of broken rotor bars in squirrel-cage induction motors. The hypothesis of this method is that, given a sinusoidally applied voltage, the presence of certain harmonics in the stator currents could be used to detect the presence of broken rotor bars.

Book Synopsis Electric Machines by : Hamid A. Toliyat

Download or read book Electric Machines written by Hamid A. Toliyat. This book was released on 2017-12-19. Available in PDF, EPUB and Kindle. 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 Induction Machine Broken Rotor Bar Diagnostics Using Prony Analysis by : Shuo Chen

Download or read book Induction Machine Broken Rotor Bar Diagnostics Using Prony Analysis written by Shuo Chen. This book was released on 2008. Available in PDF, EPUB and Kindle. Book excerpt: "On-line induction machine condition monitoring techniques have been used widely in the detection of motor broken rotor bars for decades. Research has found that when broken bars occur in the machine rotor, the anomaly of electromagnetic field in the air gap will cause two sideband frequency components presenting in the stator current spectrum. Therefore, identification of these sideband frequencies can be used as a convenient and reliable approach to broken rotor bar fault diagnosis. In this thesis, an induction machine model that includes broken rotor bars is developed using Matlab/Simulink and verified by comparing the experimental and the simulated results. The Prony Analysis method for broken bar diagnosis is implemented and tested using both simulated and measured stator current data. Comparisons between PA [Prony Analysis] and DFT [Discrete Fourier Transform] results are presented, clearly indicating improvements of broken bar diagnostics using PA." -- from Abstract.
