Book Synopsis Noise Optimized Control of an Electrical Drive with Induction Machine by : Wolfgang Bischof
Download or read book Noise Optimized Control of an Electrical Drive with Induction Machine written by Wolfgang Bischof and published by Cuvillier Verlag. This book was released on 2019-08-07 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work proposes methods for modeling the acoustic behavior of induction machines as well as optimization approaches for the control of the acoustic behavior. The aim of this work is to simplify and improve the quality of the acoustic modeling of induction machines and to show possible optimization measures in order to make the application and its understanding accessible to a broader group of users. In this work, approaches for the efficient modeling of harmonic phenomena in the electromagnetics of induction machines are shown and analyzed. This work focuses on the development of efficient geometric models for the calculation of electromagnetics of induction machines, which are substantially based on analytical equations and are used in an extended simulation via numerical methods. Subsequently, a method for the acoustic calculation of the vibrations resulting from the electromagnetic force excitation on the surface of the housing of the electrical machine is presented. The approach for the calculation of the surface vibrations is based on the system simulation and the vibration synthesis approach. The presented method offers the possibility to present extensive and realistic models and can therefore contribute to the optimized design of induction machines and many other types of electric drive systems. The procedure consists of a two-stage process, whereby a distinction is made between an offline calculation, as a prediction for model parametrization and for the calculation of the electromagnetic behavior as well as an online calculation, which includes the actual acoustic calculation. Based on this efficient calculation method, control and sensor influences as well as spatial harmonics and inverter switching frequency orders can be analyzed and optimized. In addition, two methods are presented, which refer exclusively to the changes of the software and their parametrization of the electric drive system. On the one hand, this work presents a procedure which improves the acoustic behavior by changing the operating point at constant torque and speed of the electric drive. Another method describes the injection of voltage pulses to generate harmonic current oscillations, which counteract with the excitation of occurring vibrations and thus contribute to the reduction and optimization of the acoustic behavior of the induction machine and thus of the electric drive train. Underlining the results of the presented methods, the results of the simulation models are proposed and compared to measurements.

Book Synopsis General Airgap Field Modulation Theory for Electrical Machines by : Ming Cheng
Download or read book General Airgap Field Modulation Theory for Electrical Machines written by Ming Cheng and published by John Wiley & Sons. This book was released on 2023-01-05 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: General Airgap Field Modulation Theory for Electrical Machines Introducing a new theory for electrical machines Air-gap magnetic field modulation phenomena have been widely observed in electrical machines. This book serves as the first English-language overview of these phenomena, as well as developing systematically for the first time a general theory by which to understand and research them. This theory not only serves to unify analysis of disparate electrical machines, from conventional DC machines, induction machines, and synchronous machines to unconventional flux-switching permanent magnet machines, Vernier machines, doubly-fed brushless machines etc., but also paves the way towards the creation of new electrical machine topologies. General Airgap Field Modulation Theory for Electrical Machines includes both overviews of key concepts in electrical machine engineering and in-depth specialized analysis of the novel theory itself. It works through the applications of the developed theory before proceeding to both qualitative analysis of the theory’s operating principles and quantitative analysis of its parameters. Readers will also find: The collective experience of four award-winning authors with long records of international scholarship on this subject Three separate chapters covering the principal applications of the theory, with detailed examples Discussion of potential innovations made possible by this theory General Airgap Field Modulation Theory for Electrical Machines is an essential introduction to this theory for postgraduates, researchers, and electrical engineers.

Book excerpt: Written by one of the leaders in the field, this book serves as an essential reference for the future understanding and development of rotating electric machines. First published in 1970, this classic work has endured the last 25 years by offering a comprehensive study of the fundamentals of induction machine design and application. Starting with the first principles of electric circuits, the transformer, magnetic energy storage and the virtual displacement method of calculating magnetic forces, the equivalent circuit of a motor is developed, and the formulas for performance calculations are derived. Basic formulas for torque and output are included, and extensive consideration is given to the fundamental and harmonic magnetic fields produced in the air gap by various types of winding. Speed-torque-current relations, crawling and locking phenomena, magnetic noise, and the rating and application of motors is also covered.
