Alternating current machines, also known as AC machines, are electrical machines that operate on the principle of alternating current. These machines are widely used in power generation, transmission, and distribution systems, as well as in industrial and commercial applications. AC machines include synchronous machines, induction machines, and asynchronous machines, among others. These machines are widely used in power generation,

Before dissecting the text, it is essential to understand the author. Alexander Suss Langsdorf (1877–1973) was not merely an author; he was a titan of early electrical engineering education. A long-time professor at Washington University in St. Louis, Langsdorf dedicated his life to the study of polyphase systems, synchronous machines, and induction motors. Unlike many modern textbook authors who compile existing knowledge, Langsdorf was a contemporary of the very pioneers of AC power—Nikola Tesla, Charles Proteus Steinmetz, and Benjamin G. Lamme. His writing carries the weight of primary-source authority combined with pedagogical clarity.

– A classic that survives because it answers the fundamental questions that modern, flashy textbooks often skip.
