Alexander S. Langsdorf’s "Theory of Alternating-Current Machinery" (1937) offers a mathematically rigorous foundation for understanding the principles behind electrical machinery. The text covers foundational topics, including transformers, synchronous machines, and induction motors, using vector diagrams and complex algebra to model behavior.
