Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
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.
