Variable Speed Drive Fundamentals

by Clarence A. Phipps

 

Written in straightforward "user" language, this book provides an authoritative, yet practical guide for the engineer or technician involved in specifying, applying, maintaining and operating variable speed drives, covering the full scope of both AC and DC motors and controls.

 

You will learn how to correctly apply adjustable speed drives for most common types of applications, as well as how to accurately identify machine characteristics, and how to avoid the most frequently encountered types of installation problems.

 

     Also covered are methods for controlling enclosure heat, energy saving opportunities, and useful information to speed you through calculations and estimates. A full chapter is devoted case histories which illustrate a wide variety of installations. Avoiding the excessively complex mathematical aspects of drive operation, this practical reference clearly shows you the basic relationships you need to understand to apply drive systems with confidence.
