This text investigates the fundamental physical mechanisms that generate noise in electrical motors and provides a systematic framework for noise reduction. S. J. Yang, an expert in electrical machine acoustics, synthesizes experimental data and theoretical models to explain how electromagnetic, mechanical, and aerodynamic forces contribute to acoustic emissions. The book establishes a rigorous analytical approach for engineers to predict and mitigate noise levels during the design phase of various motor types.

Experts recognize this monograph as a foundational technical reference for engineers specializing in machine design and noise control. Readers frequently note the high level of mathematical density and the specialized nature of the content, which is intended for professional practitioners and advanced researchers in the field of electrical engineering.
