Discover the history, underpinnings, and applications of one of the most important theories in electrical engineering

In Reference Frame Theory, author Paul Krause delivers a comprehensive and thorough examination of his sixty years of work in reference frame theory. From the arbitrary reference frame, to the coining of the title "reference frame theory," to the recent establishment of the basis of the theory, the author leaves no stone unturned in his examination of the foundations and niceties of this area.

The book begins with an integration of Tesla's rotating magnetic field with reference frame theory before moving on to describe the link between reference frame theory and symmetrical induction machines and synchronous machines. Additional chapters explore the field orientation of brushless DC drives and induction machine drives. The author concludes with a description of many of the applications that make use of reference frame theory.

The comprehensive and authoritative Reference Frame Theory also covers topics like:

  • A brief introduction to the history of reference frame theory
  • Discussions of Tesla's rotating magnetic field and its basis of reference frame theory
  • Examinations of symmetrical induction and synchronous machines, including flux-linkage equations and equivalent circuits
  • Applications of reference frame theory to neglecting stator transients, multiple reference frames, and symmetrical components

Perfect for power engineers, professors, and graduate students in the area of electrical engineering, Reference Frame Theory also belongs on the bookshelves of automotive engineers and manufacturing engineers who frequently work with electric drives and power systems. This book serves as a powerful reference for anyone seeking assistance with the fundamentals or intricacies of reference frame theory.
