Information

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

Resistances and stray inductances of the machine always refer to either stator or rotor. The symmetry of the stator, rotor and supply are assumed. The number of stator and rotor phases may be different. 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 rotor winding resistances
friction losses
stator and rotor core losses (only eddy current losses, no hysteresis losses)
stray load losses
