analysis of electric machinery and drive systems third edition pdf
However, whenever power system operation or system fault studies are considered, positive current is assumed out of the machine consistent with power system convention. The remaining chapters, including the chapters on electric drives, as well as the chapters on converters, have been updated to include recent advances in analysis and converter control.
Also, the analysis of unbalanced operation covered in the fi rst edition
but not in the second, has been simplifi ed and is presented in Chapter 9 .
We have spent a major part of our professional careers dealing with electric
machines and drives. We are not only coauthors but colleagues and good friends.
With the close working relationship that existed during the preparation of this manuscript,
an ordering of the coauthors based on contribution would be diffi cult if not impossible;
instead, the ordering is by age only.
