Herman/Seiler's UNDERSTANDING MOTOR CONTROLS, Cengage International Edition, is designed for students with no previous motor control experience. It introduces basic principles and common motor control components to build simple control circuits. Illustrations depict troubleshooting circuits using basic types of meters and test equipment. While the use of modern equipment is highlighted throughout the book, legacy types of timers and other motor control devices are included for reference. Updates include the most recent edition of the National Electrical Code?, clearly illustrating how to select overloads and protect the control circuitry. Motor control components and hands-on laboratory experiments enable students to practice and apply the concepts, starting with simple circuits and advancing to more complicated circuits involving timing relays, electronic control devices and auto-transformer starters.

A guide to wiring industrial buildings according to the 2014 National Electrical Code[registered]. It is suitable for apprentice and journeyman electricians, building contractors, and anyone working in the electrical field.

Prepares students for a career in industrial settings through a coverage of components and circuits in terms of how they work, what they do, how to use them, and how to test them.

Helps your students to install, troubleshoot, and test electrical motors. From development and installation to testing and troubleshooting, this book prepares industrial electricians with a foundation in basic control circuits, sensing devices, solid-state controls, variable speed drives, programmable logic controllers (PLCs), and more.

Combines an explanation of theory with practical applications of electrical machines.

Delivers comprehensive coverage and practical insight for anyone who can install, monitor, and/or maintain motor controls. This book begins by introducing the simplest of equipment and then helps you build on your knowledge as you learn step by step how to draw and interpret motor control schematic diagrams.

Suitable for service technicians in air conditioning and refrigeration, construction, and facilities management - and those who need a practical knowledge of electricity, this text begins with an overview of basic electricity concepts - rather than complex mathematical calculations.

Emphasizes the basics as it equips readers with the information needed to work effectively with all types of motors and control devices found in the heating and air-conditioning industry. This title reflects the National Electrical Code[registered] and requires no prior knowledge of electricity.
