Excerpt from The Induction Motor: Its Theory and Design When we decided to publish this work, we were aware that several authors had already given attention to the subject of making calcula tions for polyphase non-synchronous (induction) motors, and that some of them had even given complete theories on the subject. We also knew that for a few years past many distinguished professors have been discoursing at length to their pupils on these machines. It is not, therefore, for those engineers who have learned to design induction motors with these authors or with these professors, that this book has been written.
