Test example: InductionMachineSquirrelCage with inverter driving a conveyor
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
An ideal frequency inverter is modeled by using a VfController and a three-phase SignalVoltage. Frequency is driven by a load cycle of acceleration, constant speed, deceleration and standstill. The mechanical load is a constant torque like a conveyor (with regularization around zero speed).
Simulate for 20 seconds and plot (versus time):
- currentQuasiRMSSensor.I: stator current RMS
- aimc.wMechanical: motor's speed
- aimc.tauElectrical: motor's torque
Default machine parameters are used.
