Jones’ theory is built upon Gabriel Kron’s concept of the . Instead of treating every motor or generator as a unique entity, the theory represents all rotating machines as a set of inductively coupled coils arranged on two perpendicular axes: the Direct (d) and Quadrature (q) axes.

The unified theory remains an essential framework. By consolidating isolated machine behaviors into a single, cohesive matrix-driven system, it bridges the gap between historical heavy machinery engineering and modern digital control systems.
One of Jones’s most valuable contributions is his use of the —a hypothetical two‑winding electromechanical device that serves as the common ancestor from which all real machines can be derived. By specifying the winding connections, commutator arrangement, and mechanical constraints of the primitive machine, one can obtain the equations of any specific machine type. This approach, pioneered in earlier work by Gabriel Kron, was refined and expanded by Jones into a comprehensive, pedagogically sound framework.
