The IM Slip Ring component models a three-phase induction machine with a slipring rotor. The resistance and stray inductance of the stator and rotor are modeled directly in the stator and rotor phases, with a space phasor transformation and a stator-fixed Air Gap model.
The following losses are modeled:
•
|
heat losses in the temperature dependent stator winding resistances
|
•
|
heat losses in the temperature dependent rotor winding resistances
|
•
|
core losses (only eddy current losses, no hysteresis losses)
|
The turnsRatio parameter can be obtained from the following relationship at standstill with open rotor circuit at nominal voltage and nominal frequency, using the locked-rotor voltage , no-load stator current : .
