Electric Motor Control

Rating:
Summary: The book they forgot to proof!
Review: This is one of those books that spends more time telling you what you will learn from a chapter than what is actually presented in the material. It also asks review questions at the end of chapters that isn't explained until further in the book, if at all. Misprints are numerous and in some cases the material is just plain wrong, such as paragraph 1 on page 137 which claims that figure 23-1 can be locked off for safety reasons. Even if locked the start button would cause the motor to run if held in the on position. Hardly a 'safe' circuit. Our school required this book as part of its motors control course and every single student in our class is totally fed up with the errors and mistakes as well as the brevity of explanations.
