Space vector theory is the mathematical foundation of modern industrial automation. It transforms complex, time-dependent three-phase AC variables into a single rotating vector. This approach simplifies the analysis, design, and control of electrical machines and drives. 1. Foundations of Space Vector Theory

: This technique optimizes the switching of inverters to minimize energy loss and torque ripple.

: Discusses the operation and simulation of D.C. machines and variable-speed drives. Oxford University Press Publication Details Electrical Machines and Drives - Peter Vas [ Three-Phase AC Variables: a, b, c ]

Using SVT, the induction machine is modeled not by three coupled circuits, but by two orthogonal circuits (d-axis and q-axis).

Space vector models isolate the stator and rotor voltage equations. Stator voltage vector: Rotor voltage vector: ψ⃗modified psi with right arrow above represents flux linkages, ωkomega sub k is the reference frame speed, and ωmomega sub m is the mechanical rotor speed.
