This archive contains electronic files to accompany "Electric Machinery Fundamentals", third edition, by Stephen J. Chapman. It contains the m-files used to generate examples in the book, plus electronic versions of the magnetization curves used in end- of-chapter exercises. It should be unpacked with an unzip program that preserves long file names, such as WinZip. Many of the problems in Chapters 2, 5, 6, and 9 require that a student read one or more values from a magnetization curve. The required curves are given within the textbook, but they are shown with relatively few vertical and horizontal lines so that they will not appear too cluttered. Electronic copies of the corresponding open-circuit characteristics, short-circuit characteristics, and magnetization curves are supplied in this archive. They are supplied in two forms, as MATLAB MAT-files and as ASCII text files. Students can use these files for electronic solutions to homework problems. The ASCII files have the file extent "OCC" for AC machine open- circuit characteristics (open-circuit terminal voltage versus field current), "SCC" for AC machine short-circuit characteristics (short-circuit line current versus field current), "AIRGAP" for AC machine unsaturated open-circuit characteristics (unsaturated open-circuit terminal voltage versus field current), and "MAG" for other magnetization curves. Each file contains a header that describes the two quantities contained in the file, and where appropriate, the speed of rotation at which the data was taken. Both ASCII and MAT-files have been supplied for each curve, and a student can use either one in his or her solutions. The ASCII versions may also be used with non-MATLAB software.
