Updated to the 2008 National Electrical Code and featuring safety references to the most current OSHA Safe Work policies, Electricity 4: AC/DC Motors, Controls, and Maintenance, 9th Edition, provides practical, hands-on information to get the electrical system operating as well as the theory of "why" the system works to aid in troubleshooting. The Ninth Edition features material on Variable Frequency Drives (VFDs) and newer controls for servo and small motors. Current practices and equipment have also been added to the Maintenance section to better enable readers to troubleshoot motors and control problems. Features: All material has been updated to bring the "state-of-the-industry" principles and practices to new and practicing electrical workers. More control systems using programmable controls and the use of electronic controls have been added to the advancement of control systems. Current and past technologies are thoroughly examined to provide reference to older systems still in use and provide the necessary information to transition to newer systems. Formulas and examples are explained step-by-step, and solutions are provided to reinforce processes and aid in application. From the Preface The ninth edition of Electricity 4 has been updated to provide more information and better flow of concepts. New material and artwork have been added to better reflect the current workplace. At the same time, the text has retained the features and style of previous editions that have made it so popular. The text introduces the concepts of AC and DC motors, and the associated controls and maintenance of this equipment. The material is broken down into short segments that concentrate on specific concepts or application of particular types of equipment. The detailed explanations are written in easy-to-understand language that concisely presents the required knowledge. Many illustrations and photographs help provide technical understanding and provide real-world references. This type of explanation and application better prepares the student to perform effectively on the job in installing, troubleshooting, repairing, and servicing electrical motors and controls. The knowledge obtained in this book permits the student to progress further in the study of electrical systems. The study of electricity and the application of electrical products are continually changing. The electrical industry constantly introduces new and improved devices and material, which in turn lead to changes in installing and operating equipment. Electrical codes also change to reflect the industry needs. It is essential that students continue to learn and update their knowledge of current procedures and practices. The text is easy to read and the units have been grouped by general topics. Summaries of each unit provide an opportunity to restate the most important topics of the unit. Summary Reviews of the units reemphasize topic groups. Each unit begins with learning objectives. An Achievement Review at the end of each unit provides an opportunity for readers to check their understanding of the material in small increments before proceeding. Some of the problems in the text require the use of simple algebra, and the student should be familiar with the math before trying to solve the equations. It is also essential that the reader have a basic understanding of the fundamentals of electrical circuits and electrical concepts. It is recommended that the most recent edition of the National Electrical Code (published by the National Fire Protection Association) be available for reference and use as the learner applies this text. Applicable state and local codes and regulations should also be consulted when making the actual installations. Features of the ninth edition include: Updated coverage on DC motor starting. Expanded coverage of Servo motors. Explanation of high efficiency motors. An update to the 2005 National Electrical Code.
