Modelica.Magnetic.QuasiStatic.FundamentalWave.BasicMachines.SynchronousMachines.SM_PermanentMagnet

Permanent magnet synchronous machine with optional damper cage

Information

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
• 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
