Zusatztext "The presented book has a strong monograph attributes and the description of technical material is in the form of tutorials and technology overviews! combining fundamentals and advanced material. ?The book is an attractive reference book for research! consulting and development engineers who are interested in design of modern electrical machines. Also! it can be used for advanced senior-level course as well as partially in undergraduate course in university."-IEEE Industrial Electronics Society Newsletter! Vol. 54! No. 2! June 2006"Showing the strong relation between the mechanical vibration and the acoustics is particularly a great value of this book . . . represents the highest level of the theoretical explanation across many relevant areas including the electromagnetic field theory! the physics and the acoustics . . . a valuable reference book for those working with the noise of motors and the noise control in general." - Dr. Laszlo Timar-Peregrin! in Acoustics Australia! December 2007 Informationen zum Autor Gieras, Jacek F.; Wang, Chong; Lai, Joseph Cho Klappentext Presenting updated material in an accessible style! Noise of Polyphase Electric Motors features comprehensive coverage of noise and vibration of electric motors! including permanent magnet synchronous motors. This book provides examples of analytical! numerical! and statistical methods for noise analysis! describing statistical energy analysis principles and their applications. It gives fundamental equations for electromagnetic! structural! and acoustic computation of noise and vibration. It also discusses vibration and sound radiation of cylindrical shells. This text makes an ideal handbook for engineers! students! and researchers working with electrical machines and drives.
