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 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.

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.

Simple model of a permanent magnet, containing:
The permanent magnet is modeled by a magnetic potential difference. The internal reluctance of the permanent magnet is not taken into account. The internal reluctance needs to be modeled outside the permanent magnet model, e.g., by the total machine reluctance considered in the air gap model.
