Overview

The current, comprehensive, and powerful ELECTRICAL CONTROLS FOR MACHINES, 7TH EDITION thoroughly introduces technologies in today's electrical machine controls. Updates reflect the latest practices and trends with circuit diagrams and descriptions of circuits that clearly illustrate modern controls circuits. Expanded coverage addresses power and control circuitry required to operate electrical machinery. Students examine the trend away from relay control to PLC control, while this edition still maintains solid coverage of relay circuits. This edition emphasizes safety in industrial settings with detailed explanations of the risk assessment process and a safety relay circuit. Content also includes international equipment specifications.

Diane Lobsiger is an electrical instructor at Delta College in University Center, Michigan. She instructs students in the Skilled Trades-Electrician program, Wind Turbine Technology program, and Pre-Engineering program. In her prior work as a senior manufacturing controls engineer for 24 years, she gained a wealth of knowledge and extensive experience in the design, troubleshooting, specification writing, and approval of machine controls systems. Her expertise includes relay control systems, programmable logic controllers, human-machine interfaces, servo systems, adjustable frequency drives, and fluid power systems. She earned a Bachelor of Science in electrical engineering from Auburn University and a Master of Science in electrical engineering from Michigan State University. She recently obtained her Secondary Teaching Certification in mathematics and physics from Saginaw Valley State University. In her free time, she can usually be found fishing at her cabin.
  • Delivering coverage that is both comprehensive and current, ELECTRICAL CONTROL FOR MACHINES emphasizes modern control systems that contain mature technologies, expanding technologies, and new technologies.
  • Extremely reader friendly, the text presents information in a logical and systematic sequence that facilitates learning, taking readers from basic principles to advanced applications while limiting the jargon to terms widely accepted by control manufacturers and equipment users.
  • System design issues and troubleshooting techniques are applied to real-world applications that reflect the range of technologies found in today's industrial systems.
  • Highly practical and realistic examples feature the use of common equipment and procedures, enabling readers to readily apply what they have learned to solve real-world problems.
  • Concise text explanations, insightful diagrams, and engaging photographs make it easy to read, understand, and learn from the book.
  • End-of-chapter review questions underscore key points while a comprehensive glossary helps readers understand and master key terms.
  • Quick reference appendices offer instant access to frequently used electrical symbols, measurement units, rules of thumb, electrical formulas, electrical codes and standards, power factor corrections, and more.
  • Recommended web sites at the end of each chapter link readers with additional information, manufacturers, and professional organizations.
