Electric Motor Control

This highly practical approach to a difficult topic makes Electric Motor Control an especially useful and effective tool for anyone who will install, monitor and/or maintain motor controls. The book begins by introducing the simplest of equipment and then builds upon this knowledge, step-by-step, enabling readers to learn how to draw and interpret motor control schematic diagrams. Subsequent units provide useful information on motor control components and how they are connected to form complete control circuits. Thoroughly updated, this edition features an all-new unit on variable frequency drives, expanded coverage of programmable logic controllers (PLCs), plus the latest information on micro limit switches, brushless exciters for synchronous motors, and vacuum contactors. New information on the similarities and differences between NEMA and IEC control components is also included. One of the most reader-friendly, yet technically complete, introductions to modern motor theory and applications available anywhere, the book is particularly well suited for use in journeyman electrician training courses or self-study. To use it successfully, readers are assumed to have prior knowledge of basic electricity concepts.Walter N.
