modelIMC_Inverter2

Induction machine with squirrel cage and inverter, operated up to twice the nominal frequency

Extends from IMC_Inverter1 (Induction machine with squirrel cage and inverter).

Information

Description

Compared to IMC_Inverter1 in this example frequency is raised by a ramp up to double the nominal frequency in double the time. At time tStep a load step is applied.

Plot the following variable(s)

  • fActual: actual supply frequency
  • voltageRMSSensor.V: quasi RMS stator voltage
  • imc.stator.abs_Phi: magnitude of stator flux
  • imc.tauElectrical: electromagnetic torque
  • imc.wMechanical: speed
  • currentRMSSensor.I: quasi RMS stator current
