Comprehensive and up to date, this book provides crucial information on basic relay control systems, programmable logic controllers, and solid state devices commonly found in an industrial setting.Focusing on basic, singlephase, and threephase induction motor theory and operation, the book outlines common motor control circuit schemes, and demonstrates how to read, interpret, and document motor control circuit diagrams.It provides an overview of electric motor operation, selection, installation, control and maintenance. Every effort has been made in this edition to present the most uptodate information which reflects the current needs of the industry.The dot means the wires are connected Motor starter contactor coil Wiring terminals N L M M.L N S1 Figure 32 Motor starter The energy used to power motor control circuits is very small compared to the power required to run the motor.Extremely readerfriendly, the book begins with an overview of basic electricity conceptsrather than complex mathematical calculations.OBJECTIVES After studying this unit, you should be able to • describe the differences between a relay, a contactor, and a starter. • state how the lockedrotor current of a motor affects the choice of a motor starter. • list the basic components of a The One Expert Source for Switchgear and Control Information and Data. Here is the only practical reference tool you need to specify, select install, and maintain switchgear and control devices in any electrical.system.For the same static closing force, the frame and armature of a dc contactor can be smaller than that of an ac contactor. Starter Size vs. Motor Horsepower for FullVoltage Starting (NEMA) sometimes referred to as the wiring diagram, shows
