by Alexander S. Langsdorf is a seminal engineering text that remains highly regarded for its rigorous mathematical depth and clarity in explaining electromagnetic principles. First published in 1937 as part of the McGraw-Hill "Electrical Engineering Texts" series, this comprehensive volume spans nearly 800 pages, focusing on the steady-state theory of AC machinery. Overview and Academic Significance
The book addresses the complexity of single-phase induction motors, explaining why they are not self-starting (pulsating field vs. rotating field) and analyzing the "double-revolving field theory" (Cross-field theory). Theory-alternating-current-machines-alexander-langsdorf-pdf

Most texts treat single-phase motors as an afterthought. Langsdorf does not. He explains the "cross-field" theory and the "double-revolving field" theory with equal weight, then applies them to split-phase, capacitor-start, and shaded-pole motors. If you have ever wondered why a single-phase induction motor is not self-starting, Langsdorf’s answer is definitive.
