Electric Motor Maintenance and Troubleshooting, 2nd Edition provides a practical, hands‑on guide to electric motors — how they work, how to maintain them, and how to troubleshoot them. Drawing on over 40 years of the author’s industry experience, this edition includes updated coverage of three‑phase motors, the latest test instruments, and methods to decide whether to repair or replace a motor.
1. DC Machines and Testing
Learn the theory, operation, and testing of DC machines — how they work, how to detect issues, and how to perform maintenance.
2. AC Electric Motor Theory
Understand AC motor fundamentals, including alternating current, impedance, slip, and rotor/stator interactions.
3. Single‑Phase Motors
Explore single‑phase motor types, their construction, operation, common faults, and practical repair/maintenance methods.
4. Three‑Phase Induction Motors
Get detailed coverage of three‑phase induction motors: how they operate, their internal components, how multispeed and multi‑winding motors work, and how to troubleshoot them.
5. Troubleshooting Less‑Common Motors & Test Instruments
Delve into motors that are less common (synchronous, two‑speed one‑winding, multispeed, etc.), learn how to pick the appropriate test instruments, and follow step‑by‑step procedures to locate and fix faults.
Electric Motor Maintenance and Troubleshooting, 2nd Edition bridges the gap between theory and practical field work in electric motor technology. Its clear explanations, real‑world examples, troubleshooting flow charts, and tested procedures equip readers to maintain, diagnose, and repair a wide range of motors effectively. It’s a go‑to reference for technicians, maintenance engineers, and industrial professionals.
