Electrical Steels for Rotating Machines

This book provides the electrical design engineer with an insight into the properties and applications of electrical steels which are used in transformers and rotating machines.

---

Electrical steels are used to form the ferromagnetic cores of motors, generators and transformers. This book provides an insight for the electrical design engineer into what properties may be expected from electrical steels and how these properties may best be exploited in machine design.


Drawing on his extensive industrial experience, Philip Beckley presents the principles controlling the action of electrical steels, including various loss components and the influence of cutting damage. Coverage includes: general properties of electrical steels and their historical development and use; manufacturing methods; coatings and insulation; effects of punching and core building; high frequency applications; finite element design methods; testing and measurement; cost and quality issues; thickness measurement; and standards. Electrical Steels for Rotating Machines includes many useful data tables, as well as over 40 graphs of properties and performance, resulting in a very useful and practical book.


By providing details of the interplay between magnetic properties, manufacturing methods, physical properties and costs, this book will be of particular interest to electrical engineers and material producers.
