Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Resistances and stray inductances of the machine refer to an m-phase stator. The symmetry of the stator and the supply are assumed. For rotor asymmetries can be taken into account by different resistances and stray inductances in the d- and q-axis. The machine models take 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
