About

Overview

This text fills a need for a textbook that presents the basic topics and fundamental concepts underlying electric machines, power electronics, and electric drives for electrical engineering students at the undergraduate level. Most existing books on electric drives concentrate either on converters and waveform analysis (ignoring mechanical load dynamics), or on motor characteristics (giving short shrift to analysis of converters and controllers). This book provides a complete overview of the subject, at the right level for EE students. The book takes readers through the analysis and design of a complete electric drives system, including coverage of mechanical loads, motors, converters, sensing, and controllers. In addition to serving as a text, this book serves as a useful and practical reference for professional electric drives engineers.

Features and Benefits

  • Broad, flexible presentation of topics supports either a stand-alone course in Electric Drives, or a broader survey of Energy Systems, at a level appropriate for undergraduates.
  • Presents methods required to achieve speed control, position control, braking and holding of a variety of electric drives systems.
  • Covers steady-state and dynamic analysis of electric drives systems.
  • Presents the effect of the mechanical load inherent characteristic with respect to speed changes.
  • Covers the topic of trajectory control, when starting and braking times must be controlled. This topic is especially important in high performance applications such as robotics and guided manipulations.
  • The author uses his industry experience to develop real world examples and problems.
  • Bound-in disk contains multimedia software that illustrates concepts of key drive systems, plus MATLABĀ® simulations that help students understand the process of designing electric drives.
  • M-files for select examples and problems are available at www.brookscole.com.
