The induction motor: A short treatise on its theory and design, with numerous experimental data and diagrams

The literature of electrical engineering has become so vast and extensive that it is impossible for any man to keep pace with all that is written on electrical subjects. He who produces a new book that adds to the swelling tide of new publications, may justly be asked for his credentials. My justification for writing this tract will be found in the fact that, though almost all branches of applied electricity have enlisted the industry of authors, the induction motor has received comparatively little attention from competent engineers. The few whose experience and knowledge would entitle them to speak with authority on this subject are deterred from publishing by commercial reasons. I have made the induction motor the subject of early and special studies, and a comparison of my treatment of its theory with the purely analytical theories will show how far I have succeeded in simplifying and elucidating so complex a subject. The graphical treatment of abstruse natural phenomena is constantly gaining ground, and I quote with satisfaction the words of so great a mathematician as Prof. George Howard Darwin, Fellow of Trinity College, Cambridge, who says on p. 509 of the second volume of Lord Kelvin and Prof. Tail s Treatise on Natural Philosophy that the simplicity with which complicated mechanical interactions may be thus traced out geometrically to their results appears truly remarkable. All through this little book I have endeavored to let inductive method check at every step the mathematical or graphical deduction of the results. A wide experience with monoand polyphase alternating current induction motors, gained at the Oerlikon Engineering Works, Switzerland, has enabled me to do so.
