Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Quasi-static model of a DC Machine with electrical shunt or separate excitation.This model is fully compatible with the transient machine model of a DC machine with electrical shunt or separate excitation; the only difference is that electrical transients are neglected.
