Model Modelica.​Magnetic.​QuasiStatic.​FundamentalWave.​BasicMachines.​Components.​RotorSaliencyAirGap
Air gap model with rotor saliency

Information

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:

Model Modelica.​Magnetic.​QuasiStatic.​FundamentalWave.​BasicMachines.​Components.​SymmetricMultiPhaseCageWinding
Symmetrical rotor cage

Information

The symmetric rotor cage model of this library does not consist of rotor bars and end rings. Instead the symmetric cage is modeled by an equivalent symmetrical winding. The rotor cage model consists of phases. If the cage is modeled by equivalent stator winding parameters, the number of effective turns, , has to be chosen equivalent to the effective number of stator turns.

Model Modelica.​Magnetic.​QuasiStatic.​FundamentalWave.​BasicMachines.​Components.​SaliencyCageWinding
Rotor cage with saliency in d- and q-axis

Information

The salient cage model is a two axis model with two phases. The electromagnetic coupling therefore is also two phase coupling model. The angles of the two orientations are 0 and . This way an asymmetrical rotor cage with different resistances and stray inductances in d- and q-axis can be modeled.
