Book Noise of Polyphase Electric Motors

Download or read book Noise of Polyphase Electric Motors written by Jacek F. Gieras and published by CRC Press. This book was released on 2018-10-03 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Controlling the level of noise in electrical motors is critical to overall system performance. However, predicting noise of an electrical motor is more difficult and less accurate than for other characteristics such as torque-speed. Recent advances have produced powerful computational methods for noise prediction, and Noise of Polyphase Electric Motors is the first book to collect these advances in a single source. It is also the first to include noise prediction for permanent magnet (PM) synchronous motors. Complete coverage of all aspects of electromagnetic, structural, and vibro-acoustic noise makes this a uniquely comprehensive reference. The authors begin with the basic principles of noise generation and radiation, magnetic field and radial forces, torque pulsations, acoustic calculations, as well as noise and vibration of mechanical and acoustic origin. Moving to applications, the book examines in detail stator system vibration analysis including the use of finite element method (FEM) modal analysis; FEM for radial pressure and structural modeling; boundary element methods (BEM) for acoustic radiation; statistical energy analysis (SEA); instrumentation including technologies, procedures, and standards; and both passive and active methods for control of noise and vibration. Noise of Polyphase Electric Motors gathers the fundamental concepts along with all of the analytical, numerical, and statistical methods into a unified reference. It supplies all of the tools necessary to improve the noise performance of electrical motors at the design stage.

Book Analytical and Experimental Study of High Phase Order Induction Motors

Download or read book Analytical and Experimental Study of High Phase Order Induction Motors written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-17 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Induction motors having more than three phases were investigated to determine their suitability for electric vehicle applications. The objective was to have a motor with a current rating lower than that of a three-phase motor. The name chosen for these is high phase order (HPO) motors. Motors having six phases and nine phases were given the most attention. It was found that HPO motors are quite suitable for electric vehicles, and for many other applications as well. They have characteristics which are as good as or better than three-phase motors for practically all applications where polyphase induction motors are appropriate. Some of the analysis methods are presented, and several of the equivalent circuits which facilitate the determination of harmonic currents and losses, or currents with unbalanced sources, are included. The sometimes large stator currents due to harmonics in the source voltages are pointed out. Filters which can limit these currents were developed. An analysis and description of these filters is included. Experimental results which confirm and illustrate much of the theory are also included. These include locked rotor test results and full-load performance with an open phase. Also shown are oscillograms which display the reduction in harmonic currents when a filter is used with the experimental motor supplied by a non-sinusoidal source. Klingshirn, Eugene A.

Book Comparative Performance Analysis of Drives for Induction Motors

Download or read book Comparative Performance Analysis of Drives for Induction Motors written by Andrew P. Friedl and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The asynchronous polyphase induction motor has been the motor of choice in industrial settings for about the past half century because power electronics can be used to control its output behavior. Before that, the dc motor was widely used because of its easy speed and torque controllability. The two main reasons why this might be are its ruggedness and low cost. The induction motor is a rugged machine because it is brushless and has fewer internal parts that need maintenance or replacement. This makes it low cost in comparison to other motors, such as the dc motor. Because of these facts, the induction motor and drive system have been gaining market share in industry and even in alternative applications such as hybrid electric vehicles and electric vehicles. The subject of this thesis is to ascertain various control algorithms0́9 advantages and disadvantages and give recommendations for their use under certain conditions and in distinct applications. Four drives will be compared as fairly as possible by comparing their parameter sensitivities, dynamic responses, and steady-state errors. Different switching techniques are used to show that the motor drive is separate from the switching scheme; changing the switching scheme produces entirely different responses for each motor drive.

Book An Analysis of Induction Motor Applications

Download or read book An Analysis of Induction Motor Applications written by George Lowthane Greves and published by Forgotten Books. This book was released on 2017-10-28 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from An Analysis of Induction Motor Applications: Thesis Experience has proven that power may be produced more economically by one large station than by a number of small ones. It is for this reason and the additional fact that continuity of service is better assured, that the large central station has come into general use. On the other hand, the con sumers are scattered over a large territory and this necessitates the transmission of power for long distances. To avoid excess ive line losses the power should be transmitted at high volt ages, and the ease with which alternating current may be hand led makes it especially desirable. Three phase current is used because of the advantages of the polyphase motor and be cause of the economy of copper in the construction of line for transmitting polyphase current.
