modelIM_SlipRing
Induction machine with slip ring rotor
Extends from Magnetic.FundamentalWave.BaseClasses.Machine (Base model of machines).
Information
Resistances and stray inductances of the machine always refer to either stator or rotor. The symmetry of the stator and rotor is 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
