Book description
Due to a huge concentration of electromagnetic fields and eddy currents, large power equipment and systems are prone to crushing forces, overheating, and overloading. Luckily, power failures due to disturbances like these can be predicted and/or prevented.
Based on the success of internationally acclaimed computer programs, such as the authors’ own RNM3D, Engineering Electrodynamics: Electric Machine, Transformer, and Power Equipment Design explains how to implement industryproven modeling and design techniques to solve complex electromagnetic phenomena. Considering recent progress in magnetic and superconducting materials as well as modern methods of mechatronics and computer science, this theory and applicationdriven book:
 Analyzes materials structure and 3D fields, taking into account magnetic and thermal nonlinearities
 Supplies necessary physical insight for the creation of electromagnetic and electromechanical high power equipment models
 Describes parameters for electromagnetic calculation of the structural parts of transformers, electric machines, apparatuses, and other electrical equipment
 Covers power frequency 5060 Hz (worldwide and US) equipment applications
 Includes examples, case studies, and homework problems
Engineering Electrodynamics: Electric Machine, Transformer, and Power Equipment Design provides engineers, students, and academia with a thorough understanding of the physics, principles, modeling, and design of contemporary industrial devices.
