Induction machine with squirrel cage and 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).
