While Walter N. Alerich's Electric Motor Control is a technical textbook rather than a work of fiction, its "story" is the evolution of modern industrial power and the journey of a student becoming a master technician. The Context of the Work Electric Motor Control — Walter N
Walter N. Alerich was an international specialist in electrical trades and a former department head at Los Angeles Trade and Technical College
. He wrote this book to bridge the gap between complex electrical theory and the practical, "boots-on-the-ground" reality of a journeyman electrician. The "Narrative" of the Book
The book follows a logical, step-by-step progression that mirrors the career of an electrical apprentice: The Foundation
: It begins with the simplest equipment, introducing basic components like switches and relays. The Language of Power
: The "plot" advances as the reader learns to draw and interpret motor control schematic diagrams—the blueprints of the industrial world. Complex Systems
: As the chapters progress, the systems become more sophisticated. The story expands into modern technologies like Variable Frequency Drives (VFDs) Programmable Logic Controllers (PLCs) , and the differences between standards. Troubleshooting
: The climax of the learning experience is often found in the lab manuals, where the reader must "solve the mystery" of a non-functioning circuit through systematic testing. Google Books Why It Matters
