IM_SquirrelCage
Induction machine with squirrel cage
Library
Magnetic/QuasiStatic/FundamentalWave/BasicMachines/InductionMachines
Description
Resistances and stray inductances of the machine refer to an m phase stator. The symmetry of the stator, rotor and supply are assumed. 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 cage resistances
- friction losses
- core losses (only eddy current losses, no hysteresis losses)
- stray load losses
