A basic two-pole model with stationary field windings and a rotating armature.
The theory relies heavily on matrix and tensor analysis, specifically Park's Transformation and Kron's Methods , to relate physical windings to the generalized model. Key Subjects Covered in the Text The Unified Theory Of Electrical Machines By C.v. Jones Pdf
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
