Description

Parameters
Modelica Standard Library
The Fundamental Wave SM Electrical Excited (or SM Electrical Excited) component models an electrical excited synchronous induction machine with an optional damper cage. The symmetry of the stator is assumed.
The model takes the following loss effects into account:
heat losses in the temperature dependent stator winding resistances
heat losses in the temperature dependent excitation winding resistance
optional, when enabled: heat losses in the temperature dependent damper cage resistances
brush losses in the excitation circuit
friction losses
core losses (only eddy current losses, no hysteresis losses)
stray load losses
