.Modelica.Electrical.Machines.BasicMachines.SynchronousInductionMachines.SM_ReluctanceRotor .Modelica.Electrical.Machines.BasicMachines.SynchronousInductionMachines.SM_ReluctanceRotorModel of a three phase synchronous induction machine
with reluctance rotor and damper cage.
Resistance and stray inductance of stator is modeled directly in
stator phases, then using space phasor transformation. Resistance
and stray inductance of rotor's squirrel cage is modeled in two
axis of the rotor-fixed coordinate system. Both together connected
via a rotor-fixed AirGap model. The machine models take
the following loss effects into account:
Whether a damper cage is present or not, can be selected with
Boolean parameter useDamperCage (default = true).
