Summary:

Providing a detailed investigation of steady-state "eddy current" analysis and electrome-chanical processes relying on electromagnetic induction, this outstanding volume presents classical one- and two-dimensional formulations for coils, cables, and induction motors ... discusses analytical methods for optimizing performance characteristics of current carrying conductors ... gives numerous graphical field plots of quantitative electromagnetic solutions ... examines the equivalence between time dependent magnetic diffusion and induction electromechanics ... uses Systeme International (SI) units throughout the text for consistency and convenience ... and gives normalized representations of design information in graphs and tables. This profusely illustrated reference provides the wealth of design solutions that practicing engineers need in their day-to-day work. Low Frequency Electromagnetic Design is an excellent reference for electrical, electronics, and design engineers; industrial and academic researchers in electrical engineering; manufacturers of electromagnetic devices; and utility consultants. It is also an important supplementary text for graduate engineering courses in electromagnetic theory and design, and for professional seminars on electrical engineering and design.
