ABOUT THE AUTHOR
Stephen J. Chapman received a B.S. in Electrical Engineering from Louisiana State University 1975 and an M.S.E. in Electrical Engineering from the University of Central Florida 1979, and pursued further graduate studies at Rice University.
From 1975 to 1980, he served as an officer in the U.S. Navy, assigned to teach electrical engineering at the U.S. Naval Nuclear Power School in Orlando, Florida. From 1980 to 1982, he was affiliated with the University of Houston, where he ran the power systems program in the College of Technology.
From 1982 to 1988 and from 1991 to 1995, he served as a member of the technical staff of the Massachusetts Institute of Technology’s Lincoln Laboratory, both at the main facility in Lexington, Massachusetts, and at the field site on Kwajalein Atoll in the Republic of the Marshall Islands. While there, he did research in radar signal processing systems. He ultimately became the leader of four large operational range instrumentation radars at the Kwajalein field site TRADEX, ALTAIR, ALCOR, and MMW.
From 1988 to 1991, Mr. Chapman was a research engineer for Shell Development Company in Houston, Texas, where he did seismic signal processing research. He was also affiliated with the University of Houston, where he continued to teach on a part-time basis.
Mr. Chapman is currently manager of systems modeling and operational analysis for BAE Systems Australia, in Melbourne.
Mr. Chapman is a senior member of the Institute of Electrical and Electronic Engineers and several of its component societies. He is also a member of Engineers Australia.
前 言
自从本书第一版出版以来的这些年间，更大功率和更加完善的电机固态驱动装置的研发有了迅猛的进展。本书的第一版中曾经论述到，直流电动机在需要调速的应用场合是首选方法。这一表述现今已不再准确。当今，速度控制应用场合最常选用的是带有电动机固态驱动器的感应电动机系统。直流电动机已主要限定在已有可用直流电源的特殊应用场合，例如汽车电气系统等。
本书的第三版已对内容做了大幅度的重新组织，以便反映出这些变化。有关交流电动机和发电机的内容现在涵盖在第3章到第6章，先于有关直流电机的内容出现。此外，与早前版本相比，缩减了有关直流电机的篇幅。本版仍延续了这一相同的基本架构。
另外，第五版中删除了以前的第3章中关于固态电子学的内容。来自于本书使用者的反馈意见表明，这些内容对意欲快速了解者来说太过详细，但对固态电子学课程来说又不够详尽。由于很少有教师采用这些材料，所以已将其从这一版中删除了，但作为补充材料添加到了本书的网站上。继续使用该章中材料的教师或学生，可以免费下载。
在每章的开头增加了学习目标，以促进学生学习。
第1章是关于电机基本概念的介绍，并将这些概念应用到一个直线直流电机，这可能是最简单的电机的例子。第2章涵盖了变压器的内容，其不是旋转电机，但享有很多类似的分析方法。
从第2章以后，教师可以选择先讲授直流电机，或者先讲授交流电机。第3章到第6章涵盖了交流电机的内容，第7章和第8章涵盖了直流电机的内容。各章编排完全独立，以便教师可以按照最适合其需要的次序讲授。例如，重点在于交流电机的一学期课程，可以选择第1章至第6章，剩余时间用在直流电机上。重点在于直流电机的一学期课程，可以选择第1章、第2章、第7章和第8章，其他剩余时间用在交流电机上。第9章为单相和特种电动机，包括通用电动机、步进电动机、无刷直流电动机和罩极电动机。
修订并修正了习题和各章的结尾部分，在上一版的基础上，有超过70%的习题为新的或者修改过的。
最近几年，在教授电气工程和电气技术学生所采用的方法上有了很大的变化。像MATLAB这类卓越的分析工具已广泛应用于大学工程类课程的教学。这些工具使非常繁杂的计算变得简单易行，也使得学生可以交互式地探索问题的特征。
本教材不教授MATLAB ，认为学生通过以前的学习已经熟悉了其使用方法。同时，本书也不依赖于学生是否有MATLAB软件。如果有MATLAB可以使用，则可以充实学习经历。但如果没有MATLAB可用，则只需要跳过涉及MATLAB的例题，本教材其余部分的安排仍然是合理的。
在过去的25年，如果没有许多人的帮助，要完成这本书简直是不可能的。我非常欣喜地看到，过去了这么些年，这本书仍然颇受欢迎，很大程度上是由于审阅者提供的极好反馈意见。就本版来说，我要特别感谢：

I
n the years since the first edition of Electric Machinery Fundamentals was published, there has been rapid advance in the development of larger and more sophisticated solid-state motor drive packages. The first edition of this book stated that dc motors were the method of choice for demanding variable-speed applications. That statement is no longer true today. Now, the system of choice for speed control applications is most often an ac induction motor with a solid-state motor drive. DC motors have been largely relegated to special-purpose applications where a dc power source is readily available, such as in automotive electrical systems.
The third edition of the book was extensively restructured to reflect these changes. The material on ac motors and generators is now covered in Chapters 3 through 6, before the material on dc machines. In addition, the dc machinery coverage was reduced compared to earlier editions. This edition continues with this same basic structure.
In addition, the former Chapter 3 on solid-state electronics has been deleted from the fifth edition. Feedback from users has indicated that that material was too detailed for a quick overview, and not detailed enough for a solid-state electronics course. Since very few instructors were using this material, it has been removed from this edition and added as a supplement on the book’s website. Any instructor or student wishing to continue using the material in this chapter can freely download it.
Learning objectives have been added to the beginning of each chapter toenhance student learning.
Chapter 1 provides an introduction to basic machinery concepts, and concludes by applying those concepts to a linear dc machine, which is the simplest possible example of a machine. Chapter 2 covers transformers, which are not rotating machines, but which share many similar analysis techniques.
After Chapter 2, an instructor may choose to teach either dc or ac machinery first. Chapters 3 through 6 cover ac machinery, and Chapters 7 and 8 cover dc machinery. These chapter sequences have been made completely independent of each other, so that an instructor can cover the material in the order which best suits his or her needs. For example, a one-semester course with a primary concentration in ac machinery might consist of parts of Chapters 1, 2, 3, 4, 5, and 6, with any remaining time devoted to dc machinery. A one-semester course with a primary concentration in dc machinery might consist of parts of Chapters 1, 2, 7, and 8, with any remaining time devoted to ac machinery. Chapter 9 is devoted to single-phase and special-purpose motors, such as universal motors, stepper motors, brushless dc motors, and shaded-pole motors.
The homework problems and the ends of chapters have been revised and corrected, and more than 70% of the problems are either new or modified since the last edition.
In recent years, there have been major changes in the methods used to teach machinery to electrical engineering and electrical technology students. Excellent analytical tools such as MATLAB＆reg; have become widely available in university engineering curricula. These tools make very complex calculations simple to perform, and they allow students to explore the behavior of problems interactively. This edition of Electric Machinery Fundamentals makes selected use of MATLAB to enhance a student’s learning experience where appropriate. For example, students use MATLAB in Chapter 6 to calculate the torque–speed characteristics of induction motors, and to explore the properties of double-cage induction motors.
This text does not teach MATLAB; it assumes that the student is familiar with it through previous work. Also, the book does not depend on a student having MATLAB. MATLAB provides an enhancement to the learning experience if it is available, but if it is not, the examples involving MATLAB can simply be skipped, and the remainder of the text still makes sense.
This book would never have been possible without the help of dozens of people over the past 25 years. It is gratifying for me to see the book still popular after all that time, and much of that is due to the excellent feedback provided by reviewers. For this edition, I would especially like to thank:
