Beschreibung:
This book covers noise and vibration of electric motors, including permanent magnet synchronous motors. It 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; and it discusses vibration and sound radiation of cylindrical shells.
