Machines are analyzed using direct (d) and quadrature (q) axes, which simplify complex three-phase systems into two-axis equivalent circuits.
A basic two-pole model with stationary field windings and a rotating armature. The Unified Theory Of Electrical Machines By C.v. Jones Pdf
The central premise of Jones's work is that all rotating electrical machines—whether DC, synchronous, or induction—can be represented by a single model. Instead of studying each motor or generator type as a separate entity with its own set of rules, the unified theory uses a common mathematical language to describe their electromechanical energy conversion processes. Machines are analyzed using direct (d) and quadrature
