Motors and drives.

The International Society of Automation (ISA) has published a second edition of Motors & Drives: A Practical Technology Guide.

A practical guide developed by 30+ year industry veteran Dave Polka. This is an invaluable resource for design engineers, automation and control specialists, maintenance technicians, and students.A thorough discussion of drive systems and components, common motion control applications, maintenance, and troubleshooting.

This new release has been updated to reflect innovative new motor and drive technologies that are safer, smarter, and easier to program and implement; provide superior diagnostic capabilities; and deliver seamless integration.

"The second edition will continue to serve as a straight-forward guide for those seeking to understand the key engineering principles of motors and drives," says the author Dave Polka, who is a widely recognized expert in developing training and technical support materials for major drive manufacturers. "However, while basic theory of AC and DC drives haven't changed, technology certainly has. The book takes a fresh look at how market demands have advanced motor and drive technology and are pushing the industry in new directions."

As a result, Polka says he has incorporated a substantial amount of new and updated content to highlight recent technological developments, explain complex technical concepts and define buzz words-such as "harmonics" and "power quality"-in practical, easy-to-understand terms.

While demystifying drive and motor technology used in today's modern manufacturing processes, the book is rooted in the practical side of drive and motor use, with the "design engineering" side of technology presented in commonly used terms. Included are clearly stated summaries, and highly relevant review questions, glossaries, and reference tables for formulas and conversions.

The book is suited to a broad range of professionals, particularly engineers who are unfamiliar with motor and drive technology and technicians who are technically literate but not accustomed to complex theory and mathematics. In addition, design engineers, automation and control specialists, maintenance technicians, and students will find it useful for tutorials and as a desk reference.
