For the engineer who downloaded this PDF in 2021, you hold more than a scan of old paper. You hold a lens through which you can view the complexity of modern power systems with clarity, stripped of the noise of software interfaces. It is
"In a salient-pole synchronous machine, the armature reaction flux is not constant across the pole face. The direct-axis armature reaction reactance ((X_ad)) is significantly larger than the quadrature-axis reactance ((X_aq)) due to the smaller air gap along the direct axis. Consequently, the total synchronous reactance is resolved into two components: (X_d = X_ad + X_l) and (X_q = X_aq + X_l), where (X_l) is the leakage reactance. The power-angle characteristic for a salient-pole machine thus includes an additional reluctance torque term proportional to ((1/X_q - 1/X_d)\sin 2\delta)."

Title: Review: Theory of Alternating Current Machinery by Alexander Langsdorf (2021 Reprint/Edition Context)
Executive Summary Alexander Langsdorf’s Theory of Alternating Current Machinery is a seminal text in the canon of electrical engineering. While originally published in the mid-20th century, a 2021 reprint signifies its enduring value as a foundational reference. However, potential readers must understand that this book operates from a classical, rigorous mathematical perspective that predates modern computational tools like Finite Element Analysis (FEA). It is a "physics-first" masterclass, ideal for understanding the why behind AC machine behavior, though it may require supplementation for modern design applications.
