Two pulse Graetz thyristor bridge feeding a DC drive
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
In this example a PM excited DC machine is started with nominal torque at nominal speed. After 5 seconds, load torque is reduced to zero over a period of additional 10 seconds. At 15 seconds, the machine is operating at no load.
Plot torque tau, current currentSensor.i and average current meanCurrent.y. Also plot speed w, voltage voltageSensor.v and the average voltage meanVoltage.y.
