): Controls the electromagnetic torque output (analogous to the armature current in a DC motor).
The core idea of space vector theory is to treat three-phase quantities ( ) as a single complex vector ): Controls the electromagnetic torque output (analogous to
frame simplifies the geometry, the vectors still oscillate at the supply frequency. To eliminate time-varying components, the Park transformation rotates the orthogonal frame at the electrical speed of the machine ( This creates the and Quadrature ( ) reference frame: The -axis is typically aligned with the rotor magnetic flux. The -axis is oriented 90 degrees ahead of the When viewed from this rotating The -axis is oriented 90 degrees ahead of
