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 is 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
- optional, when enabled: heat losses in the temperature dependent damper cage resistances
- friction losses
- core losses (only eddy current losses, no hysteresis losses)
- stray load losses
- permanent magnet losses
