QuasiStatic Rotor Saliency Air Gap
Air gap model with rotor saliency
Modelica Standard Library
The QuasiStatic Rotor Saliency Air Gap component can be used for machines with uniform air gaps and for machines with rotor saliencies.
The air gap model is not symmetrical towards stator and rotor because 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 it 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, γs and γr are related by γs=γ+γr, where γ 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. 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
