The physics of synchronizing alternators to an infinite bus, including hunting and synchronizing power. 3. Synchronous Motors
The study of alternating current (AC) machinery forms the backbone of modern electrical engineering. Among the foundational texts that have shaped generations of engineers, Alexander S. Langsdorf’s Theory of Alternating-Current Machines stands as a masterwork of technical literature. Originally published in the mid-20th century as part of the prestigious McGraw-Hill Electrical and Electronic Engineering Series, this textbook remains a definitive reference for understanding the electromagnetic and thermodynamic principles governing AC electrical apparatus.

The nonsinusoidal EMF waveforms caused by winding distributions. 2. Transformers The physics of synchronizing alternators to an infinite
The transition from direct current (DC) to alternating current (AC) power systems in the late 19th century necessitated a robust theoretical foundation for rotating machinery. Alexander Langsdorf’s Theory of Alternating-Current Machines provides a systematic, mathematically disciplined approach to understanding how AC voltage, current, and magnetic fields interact to produce electromechanical energy conversion. Unlike texts that focus on empirical design charts, Langsdorf prioritizes the equivalent circuit and the revolving field concept as unifying principles.

Its influence continues to be felt today, with university library catalogs in Tanzania, India, the Philippines, and Uganda still listing it among their collections, proving its global reach.
Alexander S. Langsdorf, a distinguished Professor of Electrical Engineering and Dean Emeritus of the Schools of Engineering and Architecture at Washington University in St. Louis, wrote this text during an era of rapid power grid expansion.
The text is designed for senior electrical engineering students and covers the following major areas of AC theory:
