INDUSTRIAL ELECTRICITY AND MOTOR CONTROLS, EXPLAINED THE WAY THE PLANT FLOOR ACTUALLY WORKS.
It's 2 a.m. The line is down. A 50 HP motor keeps tripping its overload, the spare starter didn't fix it, and everyone is looking at you. Theory won't save you. Applied knowledge will.
THE GAP BETWEEN THE TEXTBOOK AND THE FACTORY FLOOR IS WHERE CAREERS STALL.
Most electrical books teach Ohm's Law and stop. They never show you how to size a motor branch circuit to code, read a control panel wiring schematic, wire a ladder logic circuit that actually seals in, decode a nameplate under pressure, or judge what PPE an arc-flash-labeled MCC bucket really demands. That missing layer of practical, code-aware judgment is where costly mistakes, failed inspections and stalled promotions happen.
Written by Dr. Roland K. Ashworth from decades of industrial electrical practice, this handbook closes that gap on purpose. Sixteen chapters pair condensed theory with fully worked design and troubleshooting examples, backed by practice problems and complete answer keys.
WHAT YOU MASTER INSIDE
- Foundations: circuit theory, AC, three-phase and single-phase power, conductor sizing and ampacity, voltage drop, grounding, transformers, electrical safety, lockout/tagout, arc flash, NEC and NFPA 70E practice
- Every motor family: DC, AC induction, synchronous, servo and stepper motors, plus nameplate interpretation, sizing and selection
- Protection and control: contactors, relays, magnetic motor starters, overload protection, branch-circuit design and ladder logic circuits with clear wiring diagrams
- Starting and drives: reduced-voltage and soft starting, plus a complete practical treatment of Variable Frequency Drives (VFDs)
- Panels and field devices: motor control centers, industrial control panel design, PLC-interfaced circuits, sensors, switches and field instrumentation
- Electrical troubleshooting and predictive maintenance: systematic fault-finding, diagnostics and reliability practice
- 23 reference appendices: NEC quick-reference tables, motor formula sheets, NEMA frame dimensions, starting-method comparisons, a 40-problem review set, inspection forms, glossary and job-ready field cards
WHAT IT GIVES YOU
- Confidence to size, protect and control any industrial motor correctly
- Faster troubleshooting: fewer parts swapped, less downtime
- Code-aware judgment that holds up to inspection and audit
- Exam-ready problems with answer keys for apprenticeship, journeyman and licensing prep
- Detailed illustrations and schematics matched precisely to the content
- One desk-and-toolbox reference that replaces a shelf of half-useful manuals
WHO THIS BOOK IS FOR
- Industrial and maintenance electricians moving from parts-swapper to diagnostician
- Apprentice and journeyman electricians preparing for licensing exams
- Maintenance technicians, millwrights and plant reliability personnel
- Electrical, mechanical and controls engineers specifying or commissioning motor systems
- Automation professionals working with starters, VFDs, PLCs and MCCs
- Vocational and trade school students and instructors
- Supervisors building in-house training programs
- Anyone keeping motors running safely, legally and reliably
THE PLANT DOESN'T WAIT. NEITHER SHOULD YOU.
One avoided misdiagnosis pays for this handbook many times over. Build the skill that makes you the technician they cannot replace.
