Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
This salient air gap model can be used for machines with uniform air gaps and for machines with rotor saliency. The air gap model is not symmetrical towards stator and rotor since it is assumed the saliency always refers to the rotor. The saliency of the air gap is represented by a main field inductance in the d- and q-axis.
For the mechanical interaction of the air gap model with the stator and the rotor is equipped with two
rotational connectors. The torques acting on both connectors have the same absolute values but different signs. The stator and the rotor reference angles,
and
are related by
where
is the electrical angle between stator and rotor.
The air gap model has two magnetic stator and two magnetic rotor ports. The magnetic potential difference and the magnetic flux of the stator and rotor are equal complex quantities, respectively, but the reference angles are different; see Concept. The d and q axis components with respect to the rotor fixed reference frame (superscript r) are determined from the stator (superscript s) and rotor (superscript r) reference quantities, by
.
The d and q axis magnetic potential difference components and flux components are related with the flux by:
