Description

This examples allows the investigation of characteristic curves of quasi static multi phase induction machines with squirrel cage rotor against per unit rotor speed.

Plot the following variable(s)

  • imc.powerBalance.powerStator against perUnitSpeed: active electrical stator power
  • imc.powerBalance.powerMechanical against perUnitSpeed: mechanical power
  • imc.powerBalance.lossPowerTotal as a f unction of perUnitSpeed: total loss power
  • imc.tauElectrical against perUnitSpeed: electromagnetic torque
  • imc.abs_is[1] against perUnitSpeed: RMS stator current of phase 1
  • imc.abs_ir[1] against perUnitSpeed: RMS rotor current of phase 1 (equivalent rotor cage with m phases)
  • imc.is[1].im against imc.is[1].re: stator current locus of phase 1
  • imc.ir[1].im against imc.ir[1].re: rotor current locus of phase 1
  • imc.stator.electroMagneticConverter.Phi.im against imc.stator.electroMagneticConverter.Phi.re: stator flux locus
  • imc.airGap.Phi_s.im against imc.airGap.Phi_s.re: main (air gap) flux locus
  • imc.rotorCage.electroMagneticConverter.Phi.im against imc.rotorCage.electroMagneticConverter.Phi.re: rotor flux locus
