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.
