Electrical Steels for 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.
