This newly revised edition presents the latest information on electric motors and motor drives in industry. It provides an overview of electric motor and drive theory, applications, installation, and troubleshooting. Specific topics covered include safety, drive programming, motor drive selection for specific applications, testing and start-up procedures. A wide spectrum of manufacturers and practical applications are represented in the text. Review questions and activities at the end of the each chapter provide a variety of assessment opportunities.

Drawing on over 20 years of experience as an instructor and developer of technical support and training materials for major drives manufacturers, the author of this practical reference introduces engineering concepts of motors and drives in a way that can be easily understood by both engineers unfamiliar with the technology, and technicians who are technically literate but not accustomed to complex theory and mathematics. It features simple explanations, summaries, review questions, glossaries, and reference tables for formulas and conversions. The text begins with an explanation of the principles of DC and variable frequency AC drive technology. It provides an overview of drive components and types of drives, with special emphasis given to common motion control applications for each. The text goes on to cover DC and AC motor and drive operation, step motors, AC vector motors, brushless servo motors, linear stepper and linear servo motors, drive innovations such as vector drives, PWM stepper, and servo drives. Feedback devices such as tachometers, resolvers, and encoders are also addressed as they relate to speed and torque control.Later chapters cover drive systems control methods and the maintenance and troubleshooting of drive systems. Design engineers, automation and control specialists, maintenance technicians, and students will find this to be an invaluable resource, both as a tutorial and a desk reference.

There is a large gap between what you learn in college and the practical knowhow demanded in the working environment, running and maintaining electrical equipment and control circuits. Practical Troubleshooting of Electrical Equipment and Control Circuits focuses on the hands-on knowledge and rules-of-thumb that will help engineers and employers by increasing knowledge and skills, leading to improved equipment productivity and reduced maintenance costs. Practical Troubleshooting of Electrical Equipment and Control Circuits will help engineers and technicians to identify, prevent and fix common electrical equipment and control circuits. The emphasis is on practical issues that go beyond typical electrical principles, providing a tool-kit of skills in solving electrical problems, ranging from control circuits to motors and variable speed drives. The examples in the book are designed to be applicable to any facility. - Discover the practical knowhow and rules-of-thumb they don't teach you in the classroom - Diagnose electrical problems 'right first time' - Reduce downtime

Process machines are critical to the profitability of processes. Safe, efficient and reliable machines are required to maintain dependable manufacturing processes that can create saleable, on-spec product on time, and at the desired production rate. As the wards of process machinery, we wish to keep our equipment in serviceable condition. One of the most challenging aspects of a machinery professional or operator’s job is deciding whether an operating machine should be shut down due to a perceived problem or be allowed to keep operating. If he or she wrongly recommends a repair be conducted, the remaining useful machine life is wasted, but if he or she is right, they can save the organization from severe consequences, such as product releases, fires, costly secondary machine damage, etc. This economic balancing act is at the heart of all machinery assessments. Troubleshooting is part science and part art. Simple troubleshooting tables or decision trees are rarely effective in solving complex, real-world machine problems. For this reason, the authors want to offer a novel way to attack machinery issues that can adversely affect the reliability and efficiency of your plant processes. The methodology presented in this book is not a rigid “cook book” approach but rather a flexible and dynamic process aimed at exploring process plant machines holistically, in order uncover the true nature the problem at hand.

"Electric Motors and Drives is intended for non-specialist users of electric motors and drives, filling the gap between maths- and theory-based academic textbooks and the more prosaic 'handbooks', which provide useful detail but little opportunity for the development of real insight and understanding. The book explores all of the widely-used modern types of motor and drive, including conventional and brushless D.C., induction motors and servo dries, providing readers with the knowledge to select the right technology for a given job." "The third edition includes additional diagrams and worked examples throughout. Now topics include digital interfacing and control of drives, direct torque control of induction motors and current-fed operation in DC drives. The material on brushless servomotors has also been expanded."--BOOK JACKET.
