Book Synopsis Noise of Polyphase Electric Motors by : Jacek F. Gieras
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.

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 Synopsis Modeling of Induction Motors with One and Two Degrees of Mechanical Freedom by : Ernest Mendrela
Download or read book Modeling of Induction Motors with One and Two Degrees of Mechanical Freedom written by Ernest Mendrela and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modeling of Induction Motors with One and Two Degrees of Mechanical Freedom presents the mathematical model of induction motors with two degrees of mechanical freedom (IM-2DMF), formed in the electromagnetic field as well as in circuit theory, which allows analyzing the performance of these three groups of motors taking into account edge effects, winding and current asymmetry. The model derived is based on the concept of magnetic field wave moving in the air-gap with a helical motion. In general, the rotor moves helically too with the rotary-linear slip. The electromagnetic field as well as motor performance of the particular motors is analyzed. The mathematical model of IM-2DMF is more general to the model of induction motors with one degree of mechanical freedom, i.e. rotary and linear motors. Examples of modeling two types of rotary disc motors and flat linear motor with twisted primary part are presented with inclusion of finite stator and rotor length and width effects. The simulation results are backed by the measurements carried out on the laboratory models, which were tested on the unique measurement stand.

This book was released on 2017-01-24 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides coverage of Motor Current Signature Analysis (MCSA) for cage induction motors This book is primarily for industrial engineers. It has 13 chapters and contains a unique data base of 50 industrial case histories on the application of MCSA to diagnose broken rotor bars or unacceptable levels of airgap eccentricity in cage induction motors with ratings from 127 kW (170 H.P.) up to 10,160 kW (13,620 H.P.). There are also unsuccessful case histories, which is another unique feature of the book. The case studies also illustrate the effects of mechanical load dynamics downstream of the motor on the interpretation of current signatures. A number of cases are presented where abnormal operation of the driven load was diagnosed. Chapter 13 presents a critical appraisal of MCSA including successes, failures and lessons learned via industrial case histories. The case histories are presented in a step by step format, with predictions and outcomes supported by current spectra and photographic evidence to confirm a correct or incorrect diagnosis The case histories are presented in detail so readers fully understand the diagnosis The authors have 108 years of combined experience in the installation, maintenance, repair, design, manufacture, operation and condition monitoring of SCIMs There are 10 questions at the end of chapters 1 to 12 and answers can be obtained via the publisher Current Signature Analysis for Condition Monitoring of Cage Induction Motors serves as a reference for professional engineers, head electricians and technicians working with induction motors.

Book Synopsis Design of Polyphase Generators and Motors (Classic Reprint) by : Henry M. Hobart
Download or read book Design of Polyphase Generators and Motors (Classic Reprint) written by Henry M. Hobart and published by . This book was released on 2015-09-27 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Design of Polyphase Generators and Motors During several recent years the author has given courses of lectures at three technical schools in London, on the subject of the design of electric machinery. These three schools were: the Northampton Institute of Technology; Faraday House; and University College. Various methods of procedure were employed and these ultimately developed into a general plan which (so far as it related to the subjects of Polyphase Generators and Polyphase Motors), has been followed in the present treatise. It was the author's experience that the students attending his lectures took an earnest interest in calculating designs of their own, in parallel with the working out of the typical design selected by the author for the purpose of his lectures. At the outset of the course, each member of the class was assigned the task of working out a design for a stipulated rated output, speed and pressure. Collectively, the designs undertaken by the class, constituted a series of machines, and co-operation was encouraged with a view to obtaining, at the conclusion of the course of lectures, a set of consistent designs. If a student encountered difficulty or doubt concerning some feature of his design, he was encouraged to compare notes with the students engaged in designing machines of the next larger and smaller ratings or the next higher and lower speeds. Ultimately the results for the entire group of designs were incorporated in a set of tables of which each student obtained blue prints. At two of these colleges, the "sandwich" system was in operation, that is to say, terms of attendance at the college were "sandwiched" with terms during which the student was employed in an electrical engineering works.
