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.
