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 current currentSensor.i, average current meanCurrent.y, voltage voltageSensor.v and average voltage meanVoltage.v.
