The theory's goal is to provide a single mathematical framework for analyzing all types of machines (DC, induction, and synchronous).
The final third of the book is devoted to commutator machines—those that rely on mechanical commutators to switch current in the rotor windings. Jones begins with an analysis of the commutation process itself, then introduces the as a generalized model from which specific commutator machine types can be derived. He works through detailed examples of simple DC machines, cross‑field machines (such as amplidynes and metadynes), single‑phase commutator motors (including universal motors), three‑phase commutator machines, and the Schrage motor, an adjustable‑speed AC commutator motor.

At the heart of C.V. Jones's work is the concept of the "primitive machine." This is an idealized, two-axis model (commonly referred to as the direct-axis or d-axis, and the quadrature-axis or q-axis) equipped with: Two stator windings Two rotor windings
The unified theory of electrical machines, also known as the "generalized theory of electrical machines," was first introduced by C.V. Jones in the 1950s. The theory provides a common mathematical framework for analyzing and understanding the behavior of various types of electrical machines, including:
The study of electrical machines has historically been taught in fragments. Students and engineers traditionally mastered direct current (DC) machines, induction motors, and synchronous alternators as separate, isolated technologies. However, the publication of The Unified Theory of Electrical Machines by C.V. Jones revolutionized this pedagogy. By introducing a generalized mathematical framework, Jones proved that all electrical machines operate on the exact same electromagnetic principles.
