The Complete Handbook of Electrical Motors
Selection, Installation, Maintenance, and Repair for Professionals and Serious Hobbyists
by Alumigogo Books
non-fiction
The definitive field guide to specifying, running, and repairing electric motors — without the marketing fluff.
About this book
Whether you are specifying a 5,000 HP compressor driver for a chemical plant, replacing the blower motor in a commercial HVAC unit, or salvaging a vintage lathe motor for your home shop, the decisions you make have direct consequences for cost, reliability, and safety. The Complete Handbook of Electrical Motors cuts through the noise, offering a practical, engineer-to-engineer reference grounded in physical reality, not datasheet superlatives.
Inside, you will find a structured approach to understanding motor principles, translating a load requirement into a correct motor specification, and comparing across brands. The book details installation best practices for alignment, coupling, and electrical supply, and provides a rigorous, step-by-step maintenance and troubleshooting program. It also evaluates the business landscape — from local repair shops to online reselling — and looks ahead at upcoming efficiency standards and technological shifts like integrated drives and wide-bandgap semiconductors.
This is not a catalog and not a marketing brochure. It is a working handbook designed to be kept within arm's reach of your workbench, toolbox, or desk. Every chapter includes concrete examples, specification tables, diagnostic decision trees, and practical costs and metrics, so you leave with actionable knowledge, ready to apply immediately.

★★★★★It's a solid reference, I'll give it that. The chapter on installation and the section on troubleshooting vibration was particularly useful for my work as a maintenance tech at a food processing plant. But honestly, I found Chapter 1 a bit heavy on the theoretical side. I understand we need the physics, but I was hoping for more real-world examples. It feels like a textbook sometimes, not just an on-the-job handbook.

★★★★★I run a small pump distribution business and wanted a better handle on the rest of the motor market. This book does a great job covering types and specs, especially around duty cycles and insulation classes, which I've misquoted to customers before. I docked a star because the chapter on business opportunities felt a little basic, not a whole lot of new ground for someone already selling the things. Still, worth the shelf space.

★★★★★The decision-making framework in Chapter 3 alone is worth the cost of the book. I replaced a poorly matched motor on a wood shop saw with the correct high-slip design based on the torque-speed curve charts here, and the difference is night and day. It's very well organized, so I can find things quickly. My only complain is that some of the maintenance checklists could go into more detail, but for a handbook, it hits a good balance.

★★★★★This is a surprisingly engaging read, or at least the first chapter was. It really made me think about how motors are designed to handle specific duty types, not just 'run and stop'. I appreciated the concrete example calculating energy costs over ten years versus the purchase price; it fundamentally changed how I'm going to spec motors for our bottling line. A few more case studies would push it to 5 stars, but as-is, it's a very strong reference guide.

★★★★★Purchased for a personal garage restoration project thinking it'd be more user-friendly. The author knows their stuff, and the brand comparison chart in Chapter 6 was great for my budget. But for a serious hobbyist without an engineering background, a lot of the initial chapters are dense. The glossary is a lifesaver, but I wished they'd briefly defined terms like 'stator' or 'inductance' right when they first used them instead of pointing me to the back of the book.

★★★★★Finally, a motor book that doesn't treat you like an idiot or a complete expert. The comparison between positive-displacement pump load profiles and fan loads was exactly the kind of real-world info I was looking for. The VFD compatibility section is spot-on, and it gave me a great checklist to use when I wire up new motors for my industrial kiln customers. The chapter 1 physics refresher was excellent, better than any college textbook I still have.
