: Represents complex three-phase quantities (voltages, currents, and fluxes) as a single rotating two-dimensional vector.
The concept of space vectors emerged to simplify the complex, time-varying differential equations that describe multi-phase AC machines. In a standard three-phase induction or synchronous motor, the stator windings are physically displaced by 120 electrical degrees. When three-phase currents flow through these windings, they create a rotating magnetic field in the air gap. Mathematical Transformation : Represents complex three-phase quantities (voltages

The optimized switching sequence reduces ripple currents, lowering acoustic noise and heat generation in the motor windings. : Represents complex three-phase quantities (voltages
