The developments of electrical machines are due to the convergence of material progress, improved calculation tools, and new feeding sources. Among the many recent machines, the authors have chosen, in this first book, to relate the progress in slow speed machines, high speed machines, and superconducting machines. The first part of the book is dedicated to materials and an overview of magnetism, mechanic, and heat transfer.
Abderrezak Rezzoug is professor at the Universit Henri Poincar in Nancy, France. Mohammed El-Hadi Za m is a professor at the Polytech'Nantes of the Universit de Nantes in France.
