modelSM_ElectricalExcited
Electrical excited synchronous machine with optional damper cage
Extends from Magnetic.FundamentalWave.BaseClasses.Machine (Base model of machines).
Information
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
- 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
