If you need an engineering introduction into generators, motors, transformers, and the likes this book is good. The illustrations not only show simplistic diagrams but actual machines one will find in the job. Has solved examples and end of chapter questions. Covers a lot of ground but delivers the concepts well.

terrible textbook

I took this course from the university that the author taught at. the book was this textbook. the pedagogy was terrible, some units such as (At/m) were not properly defined, the commentary was minimal except where it was copied from other books. it seems that the auther cannot be bothered to give a thorough explanation of the the basic concepts, and would only add in text as an afterthought. as a practicing professional in the field and as someone who has taught university level courses, I would say, find another textbook

I've just finished a university course with this book as the reference, and it's not been a happy experience. The author has a poor grasp of the concept of grammar-checking, and doesn't follow his own standards (sometimes including the imaginary "i"/"j" in formulas and sometimes leaving it out).

But the biggest problem is, the author makes no attempt to get the reader/student to understand WHY and HOW machine behavior is derived. Instead of deriving any equations (via KCL/KVL), PC Sen lists the equations as-is and expects you to memorize them.

Unfortunately, this is an engineering course and not English Lit: engineers need explanations and mathematics, not a "plug the variable in here and substitute to determine the answer" book.

Throughout the course the professor would have to point out inconstencies in the formulas provided and direct students to alternative online references as a substitute for this poor book's pitiful attempt at explaining power electronics to readers.

This is not a very good book to learn from. While it does have some useful example problems, the explanations are not very elucidating and the chapter problems often expect you to make assumptions that I don't think it's natural to make.

For example, in solving problem 4.9, you need to flip back 45 pages to Example 4.3 and use a chart for the machine described there. However, problem 4.9 never indicates that its machine shares these characteristics, or that you ought to assume they are the same. There have been a few other times when our professor has forewarned us that the wording in the homework problems is inexact, does not give us all the information we need, or gives us erroneous information.

I would not recommend this book to someone trying to study electric machines, especially if you're trying to learn it on your own.

This book is naffing awful. It does absolutely nothing to teach someone who's new to the material. It turned me off the subject of electric machines for so long. Don't buy it unless it's a required course text, or waste time trying to learn from this book. There are better tutorials to be found on the web using google search. The first part of the book is fine, but once the material gets even halfway challenging (3-phase and referring sides) it's like the author just abandons any effort to explain the concepts and throws you into the deep end with "example" problems that are magically solved with none of the steps being shown, unexplained primed notation and new units of measure everywhere.

It was great that the delivery date was faster that i expected.
But think to improve is the packaging of the book.
Lucky it was not raining session.
