Explore how polyphased alternating currents could change the way we generate and use electricity. This edition explains the ideas behind three-phase power and its potential for simpler, more reliable motors.

Through historical context and clear explanations, you’ll see why engineers debated these currents, how motors are designed to use a revolving magnetic field, and what early demonstrations suggested about efficiency and practical use. The book also discusses the contrast between different motor designs and the challenges of starting and maintaining large electrical systems.

Learn how three-phase systems can drive motors with less maintenance and no traditional slipping contacts.
Understand the difference between low-power and high-power motors and how their designs affect efficiency and reliability.
See how a revolving magnetic field is created and how it enables smooth, constant motion.
Get a window into early demonstrations and experiments that shaped the industry, including Frankfort and Heilbronn trials.

Ideal for readers curious about early electrical engineering and the evolution of efficient motor power.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
