Air gap model with rotor saliency

Information


This salient air gap model can be used for machines with uniform airgaps and for machines with rotor saliencies. 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 it is equipped with to rotational connectors. The torques acting on both connectors have the same absolute values but different signs. The difference between the stator and the rotor angle, , is required for the transformation of the magnetic stator quantities to the rotor side.

The air gap model has two magnetic stator and two magnetic rotor ports. The magnetic potential difference and the magnetic flux of the stator (superscript s) are transformed to the rotor fixed reference frame (superscript r). The effective reluctances of the main field with respect to the d- and q-axis are considered then in the balance equations

  

according to the following figure.

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.

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.
