Learn to install, troubleshoot and test electrical motors like a pro with Herman's UNDERSTANDING MOTOR CONTROLS, 4E. This unique, real-world systems approach to learning motor control devices introduces basic principles using numerous up-to-date illustrations and step-by-step thorough explanations. You start with basic control circuits and components and master all must-know" applications and procedures before advancing to more complex topics. Updated content reflects today's National Electrical Code. From safety and development to operations and problem solving, complete coverage prepares you to become an industrial electrician. You develop a strong foundation in basic control circuits, sensing devices, solid-state controls, variable speed drives and programmable logic controllers (PLCs) as hands-on lab experiments guide you in putting principles you've mastered into actual practice." -- Provided by publisher.
