Starting three-phase motors with confidence — practical methods, real‑world details, and clear diagrams. This book explains how to begin and run induction motors using a variety of starting devices, including auto-transformers, starting rheostats, and star-delta methods. It covers how these systems connect, how they protect equipment, and how to switch between starting and running smoothly.
- Learn how auto-transformers and resistive starters limit starting current and how to connect them in different configurations
- Compare balanced and unbalanced rheostats, and see how each affects current, torque, and speed
- Explore star-delta starting, two‑phase schemes, and starting methods for multiple motors from one compensator
- Understand safety and control features like overload relays, no-volt release, interlocking, and automatic reset
Ideal for readers who want a practical, hands‑on view of motor starting equipment, wiring diagrams, and the stepwise changes needed to bring a motor up to speed safely and reliably. It’s a good fit for technicians, engineers, and students working with three‑phase motors and their control gear.

Excerpt from Electrical Machinery: A Practical Study Course on Installation, Operation and Maintenance
During the three years from January, 1917, to December, 1919, there was published in "Power" a series of articles on practical electricity under the title, "The Electrical Study Course." For the first eighteen months the author of this book wrote the Electrical Study Course Lessons, and during 1919 edited them. After many requests for these lessons in book form, he was induced to compile these articles into a volume which this work represents. An effort has been made to include such material as would make the work not only of value as a study on elementary theory of electricity and magnetism, but of practical worth.
The first eighteen months of the Electrical Study Course Lessons have been used almost as they appeared in "Power," and also parts of the lessons during the following eighteen months. In addition to this there has been incorporated a number of articles by the author on electrical-machinery operation and connections and kindred subjects, which have appeared in Power during the last seven or eight years.
In the authors fifteen years experience in teaching industrial electricity, directing men on the job and in editorial work, it has been found that there are many features in the study of electricity that a large percentage of home students and those taking short courses find to be stumbling blocks. They get wrong conceptions of the theory or find it difficult to get a clear understanding of certain elementary laws.
