by Stephen Chapman

"Electric Machinery Fundamentals" continues to be a best-selling machinery text due to its accessible, student-friendly coverage of the important topics in the field. Chapman's clear writing persists in being one of the top features of the book. Although not a book on MATLAB, the use of MATLAB has been enhanced in the fourth edition. Additionally, many new problems have been added and remaining ones modified. "Electric Machinery Fundamentals" is also accompanied by a website the provides solutions for instructors, as well as source code, MATLAB tools, and links to important sites for students.

This book is awesome. It's a really great reference book. I bought it originally as a supplemental text for a class I took but it also turned out very handy for taking the PE exam. Must buy.
The first five chapters of this book really suffice for a good intro to electric machines. Can't really say much negative at all except in chapter 7 in the section on the rotor circuit model. Here he uses an ad hoc claim that rotor circuit voltage is directly proportional to slip-true for any positive power of slip at locked rotor and sync, slip 1 and 0 respectively. Linearity totally unjustified. This is done to derive the proper slip dependent impedance. This impedance can be derived from the model and circuit theory taking motion into account with more work and this is valid but too difficult for a basic intro(actually by reference frame arguments the voltage too has a dependence on slip-nonlinear-and is not the constant locked rotor voltage-computer simulation needed). Forgivable considering the scope and intended audience-the claim just comes across as a plausibility which will lead to the slip having the right power-it's an approximation that most if not all use in circuit model estimates. Nevertheless it deserves a 5-star particularly for chapter 2 on transformers and chapter 4 on ac machinery. As an aside I'll give the justification for the author's ad hoc claim. In the transformer model which is what is used in chapter 7 to model the 3-phase induction motor, the rotor circuit corresponds to the secondary winding of the transformer. The voltage induced in the secondary winding of the transformer is proportional to the frequency of the field that moves through the winding (through the iron core)-justified in chapter 2. This is a fixed or stationary winding with a varying magnetic field moving through it. Our rotor circuit must be viewed as stationary, i.e. we must find the frequency of the magnetic field as seen in the fixed rotor frame, this now looks like the secondary winding. Remembering the frequency of the magnetic field is essentially its angular speed (rotating field at constant speed), the frequency as seen in the fixed rotor frame is the field angular speed in this frame, which is the difference of the angular speeds (at a particular instant for the rotor!), but this is equivalent to slip times frequency of the magnetic field-you know where 2Pi goes. This then is slip times the secondary voltage. Q.E.D. His claim is now justified for the transformer model.
This is a straight forward, easy to understand book about three-phase electric systems and machinery. One of the best I have seen. Also, it is a great price. Another perk is that it appears that the author has put many electronic supplements (i.e. solution guide) to this book online. The author writes from a practical industry perspective. This is a great book.
Thank you
the concepts itself are pretty hard and may require a fair deal of time to understand. The book provides a huge reservoir of examples that helps in clarifying the concepts.
This book is a fundamental book in Electric Machines. I believe this book will keep its fundamental importance even one thousands years later!

This is a great teaching book on electric machines and is ideal for self study. However having answers to the end of chapters problems would have been great.
I keep falling back to this book with motor concepts. I've had it for so many years now and couldn't imagine continuing without it!
