WHAT THIS BOOK IS FOR

Students have generally found electrical machines a difficult subject to understand and learn. Despite the publication of hundreds of textbooks in this field, each one intended to provide an improvement over previous textbooks, students of electrical machines continue to remain perplexed as a result of numerous subject areas that must be remembered and correlated when solving problems. Various interpretations of electrical machines terms also contribute to the difficulties of mastering the subject.

In a study of electrical machines, REA found the following basic reasons underlying the inherent difficulties of electrical
